AMD A10 6800k desktop questions

[desura]

1. I hear that it dynamically overclocks. Does that mean that if I slap on a very good cooler, like say a good watercooler, that it will automatically overclock to higher speeds?

2. how big a boost to expect with higher spec ram? LIke say 1600 compared to 2133?

3. How is performance with a decent crossfire card?

3. How is performance with a decent crossfire card?

1. Yes it does but the stock cooler is good enough for it to run at pretty much max boost clocks. If you are getting a watercooler then it would be recommended to overclock manually to higher speeds. Personally, looking at the cost of a watercooler, I'd just take the cost of the watercooler add it to the CPU cost and just buy a faster CPU and use the stock cooler (FX-6300-8320 or i5).

2. CPU gains are minimal. GPU gains are around 22-24% from 1600 mhz to 2133 mhz.

3. The reported fps will go up but the game will feel choppy due to really bad stuttering. Crossfire, especially hybrid crossfire is almost pointless at this point in time. It may, and probably is a better idea to buy and athlon 750/760k and a 7750 for around the same price. a10-6800k is bit of a rip off compared to the a10-5800k which is significantly cheaper and can overclock just as high.

...the a10-5800k which is significantly cheaper and can overclock just as high.

No it can't. OC headroom is the one major advantage of the 6800 over the 5800.

Sorry, you are right. It looks like a10-6800k will get around 200-400 mhz more than a10-5800k. This is extremely small when you consider the poor scaling and the high starting base clock.

That is not worth the extra ~$15 the a10-6800k costs, just take that money and the cooler money and buy a 6350 and run it at stock on the stock cooler.

That depends on your definition. The performance of the 6800K@4.6GHz is pretty close to the i3-3240. If you can live with the slight deficit in single thread performance and extra power consumption that is. Which has been inflated out of all proportions.

Ah, but then you have to factor in the added cost of a discrete graphics card. I do agree that for pure performance, the 750/760K+HD7750/70 makes a lot more sense.

The 6800K is also the only A10 that includes the proper memory divider for 2133MHz RAM. On the others you're technically overclocking the memory controller, which voids your warranty... (not that you shouldn't be doing that, its just something to keep in mind )

 

[Madpacket]

FYI if you're considering going the 750/760K + discreet route keep in mind the 750 is based off the older Trinity chip while the new 760 is based off Richland so the increased overclocking headroom applies here between the chips as well.

 

[desura]

Eh, my main interest in the A10 is that 1) for the performance it is pretty cost-effective. A similar rig from intel would be like a G860 +...radeon 7750 which would be a few dollars more.

Of course, you still can't play BF3 on high settings.

but, it could be really compact. Like, put it in a tiny ITX case and watercool it.

If you ask me its pretty pointless to watercool a A10. A nice air cooler is more than enough and much more cost effective

"cost-effective" and "watercool it"

save money with cooling and buy a 7770 (or LP 7750 for small cases), that's 2x the 6800K IGP performance, easily, and you can save more money by going with the cheapest memory you can find, and a cheaper CPU (like the 750K)

this review was made using a crippled 7750 with 1600MHz DDR3 (slower than the APU memory!) while a regular 7750 uses 4500MHz GDDR5.

Yeah.

Out of curiosity...the AMD fusion looks like a pretty good chip. Why haven't we seen *any* windows 8 tablets with a fusion chip? I'd be all over it, personally.

NOt a fan of those clunky 15.6" laptops with like an A6.

Temash isn't competitive vs baytrail, especially at tablet power levels. Temash is even less competetive vs ARM.

If you are talking about trinity/richland at MS surface tdp levels, intel has better offerings.

i disagree, temash will have the best gpu perf compared to baytrail and any arm soc but to each their own.

Not at baytrail power levels. And you are not playing games on a windows 8 tablet anyway.

why not? also what of gpu compute?

baytrail just cant touch the gpu performance of temash nor can any arm soc.

And why is that ??

baytrail just cant touch the gpu performance of 15W temash nor can any arm soc.

Fixed.

By the time you are getting to 4-6W (a4-1200) tablet chips you are looking at 1/3 the CPU performance (two cores at 1 ghz vs 4 at 1.5ghz) and 1/2 the GPU performance (200-250mhz vs 500mhz for the gpu) of the 15w a6-5000 anand reviewed. That doesn't stack up will against baytrail. I don't really see how many people are going to be using gpu compute on a tablet.

And why is that ??

I wasn't very clear in my post.

Most windows 8 games (skyrim, TR are simply not playable at a reasonable frame rate on a6-5000 at a reasonable resolution). Any kind of android game will run fine on S600, S800, baytrail, and kabini. Furthermore like bobcat, jaguar is extremely CPU limited while gaming and at 1-1.4ghz you are almost exclusively going to be limited by the CPU with excess CPU power.

Not to mention that AMD seems to quote much higher idle power levels for jaguar compared to baytrail (anand said 0.77w for a6-5000, while more tablet CPUs go down to almost 0).

 

[Enigmoid]

Anyway here is the the a10-5800k as per the toms review.
They had some minor problems with overclocking.

BF3 SP is playable at 720p medium. Scaling from overclocked core and RAM is fairly small, 15% gain.

Power consumption is disgusting against the pentium G680 and 7750 DDDR5. Significantly more power (note that the pentium system is a mATX system) and you get half the fps in games.

Nobody expecting you will be able to play AAA titles on Temash Tablet. But there are a lot of games you can play at 1024x768. Civ V, Dirt ShowDown, Formula 1 and more. And Temash/Kabini is not CPU limited, it is GPU limited and especially Memory Bandwidth limited.

A6-5000 Kabini is a Desktop/Laptop part, Temash A4-1200 is the one that will be used in Tablets.

At 1.0ghz kabini will be tremendously CPU limited. E-350 was cpu limited in almost every single game.

Not with the iGPU, you are confusing things. Kabini/Temash is iGPU + Memory Bandwidth limited, not CPU limited.
Nobody will pair a Kabini with Discrete GPU like HD7950 or GTX680, especially with Temash in Tablets.

If you look at Notebookcheck you see that under high settings at unplayable fps (maybe 5-10) kabini is very competetive with HD 4000 ULV. At lower playable settings, it falls behind because of a CPU limitation.

E-350 was highly CPU/bandwidth limited. Jaguar at 1.0 ghz is worse than bobcat at 1.6 ghz in this regard while improving igp and bandwidth.

as compared to hd4000 but what of baytrail and arm socs?
also temash a6-1450 has a tdp of 8W but will turbo past that to 15W meanwhile the a4-1350 is without turbo and a tdp of 8W. They claim an sdp of 3W but we will see if anything becomes of that claim.

You can look at 3dmark physics for basic CPU comparisons. Kabini doesn't perform stellar (even intel's ULV performance is lacking when you factor in price and power use).

Simply put kabini takes too much power compared to ARM for basic tablet usage. CPU performance is quite low given the power consumption and while GPU performance is good, ARM is better. The only thing temash/kabini really offered is x86 compatibility and Baytrail can to that too and do better.
