Also AMD is apparently pushing the 45W class part really hard this time around...

With the A8-7600 AMD has hit or Blockbuster 45W TDP low powered APU no doubt.wink.gif

Still waiting for iGPU overclocking and RAM speed scaling to be tested.

in anandtech they didnt say anything about the heatsink used. probablyl was a weak one

givent that only the case support 80mm heatsinks in height or could be a CLC like corsair h60/55/antec 620/650

given that they think that a 45/65w cpu wont need something better rolleyes.gif

I'm still reading Anand's review but this slide does make things look rather disappointing in the CPU department (some previous paragraphs already hinted at it):


Quote:
Up to 20% IPC uplift (average ~10%).

It's not even a straight 10%, it's ~10%, which probably means PR speak for anything between 9.5% and 9.9% rounded up.

It's a good performance improvement on its own, the problem is where AMD is coming from, not to mention the 28nm process is geared towards lower CPU frequencies, meaning one thing cancels out the other.

Except it won't be available at launch, which is quite weird.

Shame HWH didnt show benchmark results at the 5ghz OC they managed frown.gif

Not sure about others but the ASRock board I initially got didn't allow for Turbo Core to be deactivated. There was a switch in the BIOS but every bit of monitoring software said it was still active when in Windows. This prevented us from doing an accurate clock vs. clock comparison.

I don't know why they don't test games most people actually play. Why do they test games people buying APUs will never play. They should test stuff like CS:GO, DOTA , LOL etc

It seems the it's real strength would be the IGP. But it isn't even that mind blowing compared to Richland. I guess the market segment would be users who are in a really tough budget that wants future-proof technologies such as HSA.

For $173, the price seems high though. I'd say a 7850k plus the fastest R7 gpu that it can crossfire with for slightly above $200.

My A10-5800k Trinity is roughly as low in idle and normal tasks as the A8 Kaveri 45W model, it cost about the same given a few months of regular price drops and performs better.

Glad i went for Trinity, from the wall my entire system is idle at under 32w (i have seen 26w with the hard discs spun down). I would think Richland owners would feel the same. Very small improvements here no need to upgrade for my HTPC/Server.

Ian over at anand (or whoever wrote the conclusion to the anand article) has some pretty harsh words for the CPU portion:
Quote:
The reality is quite clear by now: AMD isn't going to solve its CPU performance issues with anything from the Bulldozer family. What we need is a replacement architecture, one that I suspect we'll get after Excavator concludes the line in 2015.

In the past AMD has argued that for the majority of users, the CPU performance it delivers today is good enough. While true, it's a dangerous argument to make (one that eventually ends up with you recommending an iPad or Nexus 7). I have to applaud AMD's PR this time around as no one tried to make the argument that CPU performance was somehow irrelevant. Although we tend to keep PR critique off of AnandTech, the fact of the matter is that for every previous APU launch AMD tried its best to convince the press that the problem wasn't with its CPU performance but rather with how we benchmark. With Kaveri, the arguments more or less stopped. AMD has accepted its CPU performance is what it is and seems content to ride this one out. It's a tough position to be in, but it's really the only course of action until Bulldozer goes away.

http://anandtech.com/show/7677/amd-kaveri-review-a8-7600-a10-7850k/16

Though I think the GPU actually does pretty well, sure it's not as great in gaming as you'd want it to be but let's be honest here. APUs aren't ideal gaming solutions. I'd much rather look at compute performance with an APU. I think day to day tasks for offices etc. are where the chips could shine, not in gaming.

Problem being that frequency also went down 10% meaning that you get pretty much the same CPU power as with Richland.

For OCing it would seem like we need to wait for people to actually buy these since AMD didn't want to send out the samples early enough.
