I recently purchased a Trinity-powered laptop with an A4-4300M. (For the excruciating details, here)

I mentioned in linked thread above that I wanted to see how this lowest-end A-series performs on my Steam games. I didn't choose the games at random - they are simply the ones in my library that have a built-in benchmark, then I ran Oblivion and Skyrim, too (more on that later).

Some specs for the A4-4300M:
- 1 Piledriver Module (2 cores), 2.5GHz base, 3.0GHz Turbo
- Radeon 7420G: 128 graphics cores
- 35W TDP
- RAM: 4GB (2x2GB) 1333MHZ DDR3.

It only has 1/3 of the cores of an A10, and is paired in this laptop with only 1333Mhz. Whatever results we get here is going to be the worst-case for a modern-day APU.


Without further ado, the benchmarks:

BatmanArkhamAsylum01.png

There's something funky about the minimum frame rate, because I re-ran it several times and I really can't pinpoint where it stuttered. An actual playthrough from the very beginning until I defeat the first batch of thugs right after Joker escapes also gave me no stutter. I can't explain where that 1 FPS came from.


BatmanArkhamCity01.png

Arkham City is far more brutal, as expected. This time, I did notice several occasions of stutter during the benchmark run (they were pretty hard not to notice). What happens if we turn off everything and remove AA?


BatmanArkhamCity02.png

Well, it helped the average and max FPS a bit, but the minimum dropped. It's probably a CPU-bottleneck scenario that causes the minimums here, so it fluctuates regardless of the graphical settings. It's definitely not going to be as enjoyable to play here as Arkham Asylum.


COH_Tales_of_Valor.png

Is it just me, or does the Company of Heroes: Tales of Valor benchmark really have nothing to do with actual gameplay? It looked like a movie of some sort, whereas the game is pretty much a 3D top-view strategy thing. Average and Max are good, Min is dreadful (this is pretty much a pattern for this APU).


FarCry2.png

Far Cry 2 is absolutely brutal. I started benching at Medium, but the results were too poor when it came to the Action Scene Playback bench (Ranch was ok, though). I dialed down on the settings until I was at the lowest, but even then the action scene proved brutal. It's possible to enjoy Far Cry 2 on this APU if you are the stealthy type, but a full-on assault with multiple enemies on screen all firing at you will quickly stutter like crazy.


HalfLife2LostCoast.png

Steam's built-in bench here only provides the average FPS. We know the Source Engine would provide the highest scores here, anyway. No surprise.


JustCause2.png

Just Cause 2 proves to be very brutal here as well. Like Far Cry 2, I ended up having to dial the settings way down until I ended up with the above. Dark Tower and Desert Sunrise aren't too bad, actually, even on higher settings, but Concrete Jungle simply destroys performance. Given how Just Cause 2 is, I'm not sure there's anyway to say it's playable here unless you avoid all violence and never try to glide with your parachute by hooking into fast-moving vehicles. That's just not how Rico Rodriguez rolls, ladies.


X2.png

This one is pretty playable, as you would expect from an old title, almost as fast as HL2:LC. I would have preferred the most recent X3 game to bench, but for some reason the built-in benchmark for any of the X3 games are always grayed-out / inactive. Their support forum says that is expected, it's disabled for some reason that isn't totally crazy.


Oblivion.png

Now, this game is important to me personally because several years back when it was released, I had an 8500GT and of course it wasn't a good experience outdoors (indoors was fine), and it sucks to have it stutter heavily while foraging through the forest or running after deer or something. To solve that problem, I got an 8600GTS (a full-blown 8800GT could not fit in my small case back then), and off I played Oblivion for hours and hours on end. This is the only scenario I've encountered where I didn't upgrade because "it was time", and instead I had to because I wanted to play a game that refused to play sufficiently well on current hardware.

The experience with the A4-4300m is pretty much similar. Now, I don't have numbers for the 8600GTS, but it is certainly no worse than it, at least for Oblivion. So what I can say for sure is that the A4-4300m is definitely way better than an 8500GT, and is at least as good as an 8600GTS, at least for Oblivion.

What about Oblivion's successor?


Skyrim.png

At the settings above, there is minimal noticeable stutter despite the dips below 30. I ran through the sparse forests, looking at bushes, trees, flowers, the sky, the mountainous horizons, chased a deer, and then in turn got chased by a Mammoth (while at level 1). Although not part of the benchmark results above, I ended up playing Skyrim for real for about 2 hours. I also tried killing the guards at Whitewood. I found even my level 1 hero can take them on, if one at a time. Eventually, they ganged up and did unspeakable things to my poor hero. It was a nice experience overall, though. I completely forgot I was playing on a laptop just to bench the weakest of the A-series on a $300 HP ProBook.


Final thoughts:
If some of you are wondering what kind of performance can be had from a low-end APU, or from a particular laptop with similar specs as this one, here you go. It's not awesome, and some games will simply be unplayable (either due to the limited graphics or limited CPU power), but some will be playable enough. If you aren't buying it for gaming (specifically thinking of laptops here like the ProBook), then it's certainly a welcome bonus that games like Skyrim will be perfectly playable without looking absolutely horrid.

More than anything, I'm just amazed at how our tech continues to improve. I wouldn't want to use this as an everyday gaming rig, that's what my high-end desktop is for when it's not also doing real work, but for the value it presents, I can't help but salute the engineers working on this tech now - Intel, NV, AMD. At least with this kind of capability, I can fire up a game like Skyrim at the airport while waiting to board, or when I'm pretending to listen to some people at a meeting when they are just wasting my time - all on a $300 laptop. That's pretty cool.

This seems like a great APU for older titles. Surprised at how well it works for skyrim.
I wonder if it's finally good for general tasks. The E-350 I installed for my uncle just won't accelerate videos and it shows it lacks the horsepower for CPU rendering.

Great post jvroig. I play lot's of games on my HTPC rig (A8-3850) @ 720p and some games even @1080p. Theses are not for gaming primarily but do a decent job on not so demanding titles. I'm even contemplating exchanging my existing laptop (i7 2630, Radeon HD 6750M) for one with i7 and Iris iGP.

Can you install faster ram modules? that would help greatly.
Hey Jaydip,

You're right, it probably would help a lot in some of the titles, but I don't have any faster SODIMM's lying around.

I don't think I can scrounge up the time and motivation to re-bench these titles or others even if I did. I replaced the harddisk (a 500GB Hitachi) with a small Plextor M1 SSD (60GB). After Win7 and my work files, I only have 10-20GB to allot for Steam to make the benching happen. So for the big games, I literally had to restore them from backup, then bench, then uninstall them before restoring another game from backup.

As I said from the preface, the data points here are pretty much the worst case you can expect from a modern-day APU, seeing as to how this laptop sports only the weakest A-series and is hobbled by slow RAM.

Yeah, Skyrim pretty much surprised me too. It even looks beautiful, I'll see if I can post some screenshots.

As for general tasks, since this has Piledriver cores instead of Bobcat ones in the E-series, the difference should be stark. I'd imagine that for any normal, reasonable definition of "general tasks", any modern Celeron or A-series will do just fine.

Great benches. I know that those APU respond EXTREMELY well to faster RAM. You can almost gain 50% performance by getting faster RAM. Well, at least you can with A10's. There may be less of a benefit with slower chips.

Thanks, Gikaseixas.

I've been contemplating going discrete-less myself. The A10 graphics performance would be good enough for me (better if they mitigate the memory bandwidth problem like with Intel Iris), but unfortunately not the CPU part. I dream of a really compact rig that can sustain my modest gaming needs. Unfortunately, at its current iteration, the A10 just isn't the SKU yet for me, nor are the current Intel HD4000 parts.

Like you, I'm very intrigued by the i7 with Iris - it finally promises a no-compromise SKU. Intel-class CPU performance + AMD-class GPU performance (so to speak). When parts like this become more mainstream, whether from AMD or Intel, I might just finally find an APU that's good enough for me.

Thanks. Memory bandwidth is indeed the current bane of APU's of all shapes and sizes. I'm sure there is some more performance to be had with faster RAM, and indeed 1600MHz would have been my first choice here (they are only $2-3 more expensive than the 1333MHz version; unfortunately, when I went out for more RAM, the store only had 1333 in stock, and APU gaming really wasn't my intention here, so I just bought what was available).

However, as you so note, given how much weaker this is compared to an A10 (1/3 of the cores) and how much more prone to being CPU bottlenecked (1 module, low clock), the gains would probably be less than 50%. 10-20% is probably right, depending on game. And for titles like Mass Effect where the CPU bottleneck is extreme, it's a non-factor.


Cool story: This laptop actually did have an A6 and A8 version. The A8 is only minimally more expensive, about $450 maybe vs $320 for this A4-powered one (if you read the very long origin story of this laptop as linked in the OP, I'm not actually using dollars, so I'm converting currencies in my head). I thought: "Why bother? I only want to buy this because it's cheap, and it's not like the extra graphics of the A8 will do anything for me, APU gaming is pathetic".

If I knew then what I know now about the A4's capabilities, I might have opted for the A8 version instead. But then again, since I only got this as an impulse buy, that's probably not gonna happen because $450 is a little bit beyond "impulse buy" territory for me with regards to laptops.

@ jvroig before I forget it was very cool
Thank you, sir :)

I already had the figures to sate my own curiosity, so I thought why not take the small extra step to post them here so others could use them as reference for whatever purpose, instead of having the figures locked with me forever and ever.

Remember most prescripted benchmarks put a very low CPU load. So actual ingame FPS might be different. Specially with the TDP limits.

That's true, which is why I also played through them after the benches to confirm whether the bench results do reflect at least some of the actual game experience. See, for example, my commentary on Arkham Asylum, Just Cause 2, Far Cry 2.

Oblivion and Skyrim are completely non-canned benches.

Yep. Very nice :)

One of the more extreme cases is Tomb Raider (Thats not in your list.). Night and day between ingame and benchmark FPS.

I have an A8-4555M APU based laptop and it only comes with a 4 cell battery which gives me about 3-4 hours of battery on balanced usage(some netflix, simple browsing, etc.).

Your post made me wonder why your APU is 35W TDP while mine is only 19W! Can higher clock speed make such a huge difference?

3-4 hours, even 6-7 hours, is possible, I've found. If I'm only coding (so that's pretty much typing most of the time, then running it every now and then to check/see results/debug), it lasts well over 4 hours. If I'm really just typing stuff, even with wi-fi on for the occasional "google fact-checking", it's 6 hours.

On gaming, it depends on the game, but in heavy usage like Skyrim, it won't make it to 2 hrs. The battery life is really from the APU idling at crazy low levels.


Your post made me wonder why your APU is 35W TDP while mine is only 19W! Can higher clock speed make such a huge difference?
Well, the 35W TDP is the "family" TDP rating - it's pretty much 35W from A4 to A10, much like how several desktop SKU's share a TDP (say, all of them marked as 95W or 77W) even though logically you'd know that the lower end of those SKU's probably consume far less.

This is the chart I referred to for the info (I found it hard to find info about the A4-4300m, because it wasn't part of the initial Trinity launch, therefore not part of any launch review):

APU_specs_comparison_highlighted.png

I highlighted the 4300m myself. I can't remember where I got the original image, but it took some google-fu before I stumbled upon it, after some frustrating minutes trying to navigate AMD's site (Intel ARK is definitely a lot more usable and a lot more complete).

I don't see your SKU, and the chart itself could be wrong, so perhaps my classification of it as 35W TDP is also wrong. Or, perhaps the 4555m is one of those special "lower-power" / "lower-voltage" binned SKU's. I don't really know.

Nice review! :thumbsup:

Low-end or not, MANY people could be having a similar laptop to this.

Kind of surprising! Slowest APU can run some very popular, not so old games at high settings giving playable (or almost playable) framerates!
If Kaveri brings SR with nice improvements to core performance and on top of that they put GCN cores to play... I may be getting an APU laptop. No dedicated graphics card should drop the price a bunch.

Indeed. Before I embarked upon this experiment, I was really just curious while expecting a truly horrendous experience. My experience with integrated graphics in laptops (of course, back then they were integrated in the motherboard, not the CPU itself) is really very sub-optimal, so my expectations were pretty low for the bottom-of-the-barrel APU on a bottom-of-the-barrel HP laptop. Being able to play Oblivion and Skyrim comfortably was definitely a very nice surprise.

Now that I've thought more about it, this is one of those things you can view from a glass-half-full or glass-half-empty POV. You can either say, "Wow, tech is much better/cooler now!", or be on the more pessimistic side and say "this is how much the consolization of games have affected PC game development, advancement has slowed so much that even low-end APU's can play them!".

Whatever the POV, though, the reality is that compared to 5 years ago, lowest-end laptop integrated graphics seems much more capable today. It's a much better life for poor students, I suppose. Get a $300 laptop for all your school work, it can last 6 hours for note-taking while on battery, and then at home you can play Skyrim on it. That kind of scenario was just not possible on laptops five years ago for comparable price.

Jvroig, it's 1x4 GB 1333 Mhz or 2x2 GB?
Radeon 7420G isn't strong IGP, though it should benefit from dual memory channel instead of single.

Btw, I'm very interested in results of A6-5200 vs A4-4300M on GPU side - Kabini have also 128 SP although on higher base clock (600 Mhz vs 480/655), however at significant lower memory bandwith (64-bit MC vs 128-bit).
Of course it's GCN vs VLIW4 too.

It's 2x2GB. That's very important information I completely glossed over! Thanks, I updated the OP to make it clearer.

(Note that this laptop came with only 1x2GB, I just added the cheapest Kingston 2GB DDR3 stick I could find to populate the extra slot; most ProBook models actually do come with 4GB, this model is the only exception I found. I'm not sure if those are 2x2GB or 1x4GB)

Indeed. I'm also interested in an Ivy-Bridge based Celeron-powered laptop at the same price point, to see how it shakes out. I'm guessing that at the lowest-end, Intel HD Graphics isn't really very far from its AMD counterpart, with the possibility of significantly better CPU performance (depending on how high/low the Ivy Celeron would be clocked).

Could it be possible for you to make additional tests, to show how Radeon 7420G performance would be affected by single memory channel configuration?

But I'll keep this in mind and if I manage to get a lazy weekend in the coming weeks, I'll put this in the TO DO list for sure.

Try to overclock CPU and GPU as well... wonder how much can be squeezed out of this APU

These APU's are great for the back to school crowd. In Canada FutureShop and BestBuy were selling a 15.6" HP with the fastest Richland A10 with 8GB (2x4) 1866 and a 1TB HDD for only $399.

That system at native res can pretty much play most of today's games at medium settings without too much effort.

If you’re not terribly picky about framerates or a competitive gamer these APU's hit a very good spot.

Unfortunately, the BIOS gives me no such option, and neither does the HP-specific Catalyst Control Center (I say HP-specific because it's the model-specific driver downloaded from the HP site, not the generic one from AMD). Not really surprising for a laptop, though. It gets pretty hot with a game of Skyrim (I mean, I can feel that the air it is blowing out is really hot if I place my hand in front of the exhaust vent; I've never seen throttling happen though, so the cooling system is adequate), so I'm not really sure how much more performance could be squeezed out of it due to cooling limitations.

n Canada FutureShop and BestBuy were selling a 15.6" HP with the fastest Richland A10 with 8GB (2x4) 1866 and a 1TB HDD for only $399.
Wow, that's certainly a deal. 15.6" is a bit too big for my own tastes (i.e., lugging it around everywhere I go; I've found 14" to be the biggest that is comfortable to me), although if the price+specs were right (like in your example) it won't exactly kill me and I'd probably consider it at the very least.
