[Various] AMD Kaveri A10-7850K (7700K, 7600) reviews - Page 17

post #161 of 1004
I read only the Anandtech review and i have formed some opinion
1.The biggest improvement is that the 45W Kaveri models offer similar performance to the 100W Richland/Trinity models which means the naysayers can quiet down about higher power consumption compared to an i3 for example which in itself would provide much inferior performance or cost way more paired with an entry level GPU while also consuming more power than Kaveri.So AMD has done really well in this regard.
2.However i see no reason why i should care for the K models of Kaveri as they provide no tangible improvement over the Trinity/Richland 100W models while consuming much more power than non K models or an i3.So the K models are useless as they cost too much compared to non K models while being power hungry and not enough performance gain.
3.The APU's are ONLY targeted towards entry level gamers as i see no reason why anyone would want to choose an APU (especially a K model) over a pentium or i3 for office and basic work.
4.As for benefits and promise offered by HSA,HUMA,Mantle etc since none of these are mainstream yet it cannot be used as a feature of the APUs or as an excuse of their advantage over Intel i3/Pentium.
4.Also AMD failed in another area that could have been vital for gamers-Dual Graphics.

Pardon?
The efficiency of Kaveri in the 45W space is great it actually it is faster at 1080P than Iris pro tasks while that is a 65W chip.
The efficiency is great actually well beyond expectations.

Just because the floating point performance is still garbage doesn't mean it is a bad chip actually I think eventually AMD will ditch the FPU's and use the gpu side for it.

Not to forget, with the APU, you've the ability to add a R7 series discrete GPU in Crossfire as well. thumb.gif

Few bundles on newegg have BF4 bundled with them

Do you even need to test with a quad. How does the 4340 compare to the 7850?

so apparently BF4 is bundled with A10 apu-s biggrin.gif awesome

I am kinda disappointed. I expected a LOT higher GPU performance from the 7850K... I know it's only an iGPU, but with all the talk going around, I honestly expected somewhat closer to x2 the performance over the 6800K.

I'm guessing that the lack of viable memory bandwidth is the issue here, as it usually is with these iGPU situations. I imagine that the addition of faster system ram will benefit the flagship model in ways that seem minuscule to the other models in the past.

I'm beginning to think "APU optimized process" is AMD not trying to cause a ruckus with GloFo when GloFo failed to deliver a good process yet again.

The chip has great IPC improvements, but it's all thrown away from what happened with GloFo and not being able to clock that high.

I don't get AMD sometimes, they can release a high TDP CPU, but then they come along and cut down clocks to make sub 100w on their flagship APU. AMD should have pushed 7850k to at least 4ghz, even if it would end up as a 115w part, made is difficult to find. Basically, just a product to look good in benchmarks. Then, they should have released 7800k as what 7850k is now, the best binning they can do to keep a CPU under 100w. That's what nearly everyone else does, with at least some of their product line.

Instead AMD chooses to subject itself to endless comments about how Bulldozer is doomed and Steamroller is a disappointment.

At least we know why there's no Steamroller FX. Everyone would be pretty mad if AMD released a new chip with better IPC that didn't overclock as well. Intel can get away with it because they're Intel, but AMD doing that would be a cacophony of "ZOMG AMD IS FINISHED"

At least on a positive note, the way 28nm scales to high TDP, and how the lower TDP Steamrollers are great, and the higher up the product stack you go, the worse things get, it's a strong indicator that the fact that AMD has no good place to make a big, high TDP chip besides 32nm SOI as a reason for why AMD HEDT lie is in limbo right now.

EDIT: it looks like it's going to be a great laptop and mobile chip at least.

Am I missing something? There doesn't seem to be any HSA applications on those reviews

I do believe that people were expecting too much from DDR3 dual channel vs GDDR5 of HD7750

For all the floating point from the GPU I'd expect a better hash score in Truecrypt than i3 Haswell & better x264HD performance , so at least it achieved that

As expected, raising the voltage has a significant effect on the power consumption of the processor. One thing I should point out is that even at stock, the power delivery VRMs were getting very hot to touch – so much in fact that the system generated significant errors without an active fan on them. This got worse as the system was overclocked. I am not sure if this is an effect of the platform or the motherboard, but it will be something to inspect in our motherboard reviews going forward.
on Asrock board with LowRDs(On) instead of the Gigabyte UP4, what was expected...

Result with A88X Sniper (shouldn't be better because it's still Low Rds(on)): 5Ghz on air.

AMD performance lives and dies with OpenCL...

You are a failure for lying to everyone... You specially ignore Metro Last Light that is CPU and also GPU intensive... Good job.

Yes but not the way you wrote it DDR3 at twice the effective clock will yield the same as DDR4 at half the effective clock as long as the bus width remains the same.
I myself like to say DDR3-1066(rather than 4266) by naming the base clock rather than the effective clock speed you can't make mistakes.
If you list effective clock speeds and you double DDR3 that would make DDR3 twice as fast as DDR4 and we can easily see this by dividing 4266 by 4 and dividing 2133 by 8.

The base DDR3 clock would be 1066 and the base DDR4 clock would be 266(which is rather low and would make it perform at only half the speed as DDR3-1066 would do)

The best way to remember is that the effective clock speed is an easy way to see actually speed while the base clock speed is an easy way to state at what clocks the memory is running. thumb.gif
