Temash A6-1450 review

[Enigmoid]

Finally a review from a more reputable site (though they seem to love synthetics).

http://www.notebookcheck.net/Review-AMD-A6-1450-APU-Temash.92264.0.html


Fairly good for its tdp.

GPU seems quite good but the cpu holds it back horribly.


- low med. high
Battlefield 3 (2011) - 10.3 7.8 6 fps
The Elder Scrolls V: Skyrim (2011) - 14.4 9.2 5.9 fps
Anno 2070 (2011) - 28.7 12.2 7.8 fps
Diablo III (2012) - 26.1 16.4 13.8 fps
Dirt Showdown (2012) - 15.9 12.6 11.5 fps
Sleeping Dogs (2012) - 16 12.8 5.8 fps
Counter-Strike: GO (2012) - 17.4 14.3 11.9 fps
Dishonored (2012) - 16.2 13.1 11.6 fps
Call of Duty: Black Ops 2 (2012) - 20.2 14.1 6.9 fps

Not a single playable game (maybe anno and diablo but thats at 1024x768 low)

 

[Rvenger]

Not impressed. CPU is way to slow.


Didn't they show this game playing Dirt 3 at 1080p? Why is Dirt Showdown running like a slideshow?

 

[Madpacket]

A little disappointing TBH. I agree with the review where they say AMD should have stuck to two faster cores instead of 4 slower ones.

 

[ShintaiDK]

The low CPU performance, in more detail the low performance per core, slows down the graphics card in many games. We want to illustrate this with an example:

Makes me think on the PS4.

 

[SiliconWars]

Take all those fps numbers and divide by 10. Now you have the gaming performance of the competition.

 

[krumme]

What a shitload of skewed BS guys - man up!

This is a tablet APU.

This cpu have 80% better ipc than Atom. Probably in the order of 200% better fpu performance. And in the order of 3-400% percent better gpu performance than Atom. And working drivers - Try to execute those games on Atom. All with southbridge integrated. All in a small and dirt cheap package that can compete with arm.

You want to prove this tablet can not play metro? LOL. Get serious, and keep the post and the link to the proper thread. There is no need to repeat yesterdays news here Enigmoid.

 

[SithSolo1]

Me thinks both the cpu and gpu are throttling under gaming loads as the chip is hitting a hard TDP limit. The PS4 will not have the same issue.

It's disappointing because it's an unbalanced APU, they are starving the GPU with the low clocks. Why use a powerful GPU with such a slow CPU? Isn't that a waste of transistors?

I failed to see your point. They didn't test tablet. They tested notebook (although with touch screen). So it makes sense to compare it to notebooks. There is no point to compare this specific APU to atom based tablets at all as it's missing some essential tablet features (such as low power Si0x states and low enough TDP which allows fanless tablet design).

There is a 2 GHz version of the same chip - this is the slowest version of the full APU. There will be lower power versions with two cores and only one graphics compute unit.

This one is unbalanced but the fastest chip will be a lot better.

We have already seen Temash in fanless tablets - it cannot turbo to 1.4 GHz without the turbo dock. This is a notebook capable of 1.4 GHz which is why it has a fan.

According to the review, this APU consumes >6W running Prime (cores at 1Ghz) and ~11W running Prime+FurMark (cores at 0.85GHz). There is no chance 4 cores are going into fanless design. Maybe 2 cores APU.
Any way this specific APU is rather targeting notebooks than tablets.

and i am thinking that sony should have cut some cores

I can see your point. But I think you're failing to realize just how many Brazos-based notebooks there are out there. This A6 is faster then most Brazos-based notebooks out there. Brazos is even being used on 15.6" notebooks, and they seem quite popular, not least due to their extreme low cost. That's something an awful lot of people care about, they don't care as much for performance... :whiste:

The system consumes +6W running Prime95. While running FurMark - which is a power virus and shouldn't be used anyway - the system consumes 11W more.

Clearly the graphics are using up a lot more power than the cpu is, but the graphics are overclocked by 60% over what they'll be in tablet mode - that's going to use up a lot of power.

I'm sure we will see the 1450 in tablets - the best binned cpu's no doubt but that's how it works.

Yeah but the atom z2760 is using a lot less power (think 3-4 watts).

Probably the most relevant power test is 3dmark 06, almost 20 watts. Idles at ~10 watts, The soc is using 9 watts here.

9 watts is pretty high for a tablet (probably going to require a fan or something).

The problem with this chip is that its using too much power for a tablet and isn't quite powerful enough for a notebook.

Given its target market and thermal considerations they should have released a dual core and the same gpu and actually had the dual core reach the 1.4 ghz turbo consistently.

You are also forgetting this is AMD's first APU silicon on 28nm node . With time the power/thermal specs will be improved and I expect new models with lower TDP spec or higher clocks in Q3 or Q4.

Hopefully AMD can take advantage of the time gap between the release of temesh and silvermont to actually get some product design wins, because this seems like a pretty decent APU.

 

[SPBHM]

ST performance on cinebench for the 1.4GHz jaguar core gives half the score as the 2.6GHz piledriver core from trinity (if turbo actually works as expected)?

I wonder how far they could go with the clock for this CPU with a 35w TDP,
MT should always scale better than piledriver...

bobcat could run as high as 2.2GHz I think (but the highest models were 1.65?)

unfortunately at 1GHz CPU performance is to low for the good IGP to make any sense (for gaming), but considering the price, I guess is not to bad that it can sort of run a few new games at 15-20FPS, Atom can't at the moment, but the ulv i3/i5 run games better at comparable power usage I think,

 

[Gikaseixas]

It needs higher clocks to drive that (decent) GPU. It's a waste of GPU in that application.

 

[formulav8]

I'm not seeing anything all that bad? If you keep it in the realm of tablets it is quite good unless I missed something?

Dont know. As the cores dont cost anything to add, if they can lower implementation cost thats probably the reason. We dont like it, but probably we will see lots of this type in notebooks because then the OEM can save 2 usd on the fandesign compared to fx. a 25W kabini, and use an even slimmer battery. We also have to face to fact that these machines are designed with very little cost meaning we get lousy bios and implementations in general. All for selling this to everyone and his brother.

And ofcourse this temash variant is meant for docking purpose as the tdp far exceeds the tablet demands (and yes the variant is unballanced imho). I wouldnt be surprised to see fanless labtops with temash. Then they can be even slimmer, smaller and ....cheaper

There is absolutely nothing wrong with the APU from a technical perspective. The problem is, there is very little profit in this market for AMD, and its the only cpu product in AMD portfolio that earns anything. The rest is just waste.

compared to Surface PRO is not impressive, but to most the other tablets I think it is.
but the power usage is probably around the surface pro, not the ARM or Atom tablets.

It's a really odd view to take to see this taking over for Brazos and think it's not very good. There will be a 2GHz Quad core version with more GPU and 25W TDP as part of the family. Should also be a dual core model with at least 1.6GHz and possible turbo, after all there is a 1.65GHz dual already announced for the embedded market.

 

[SiliconWars]

Double the power usage. The ULV's are running at 17W without southbridge and this is probably running ~9W maximum with turbo operating.
