AMD Kaveri Review: A8-7600 and A10-7850K Tested
by Ian Cutress & Rahul Garg on January 14, 2014 8:00 AM ESTProcessor Graphics: Compute and Synthetics
Our GPU Compute tests are designed to stress the integrated graphics of the system using old and new GPU tools. This is where the benefits of Kaveri should come in – if a benchmark is programmed to take advantage of the GCN architecture then the relevant speed up should be observed. In none of the GCN benefits have any use then we are relying on pure grunt to get the top scores.
CompuBench CL Fluid GPU + Computer Vision GPU
CompuBench CL is an OpenCL compute benchmark designed to test some common in-use algorithms. Due to the way it is designed, any OpenCL compatible device can run the benchmarks, and as such we have run both the Fluid Dynamics and Computer Vision portions on the CPU and integrated graphics on each processor we have tested. Here are the GPU results.
GCN really wins out here, showcasing how important OpenCL compliance can be to extract potential compute.

I did a look back to C2D this time last year: http://www.anandtech.com/show/6670/dragging-core2d...When I get into the swing of testing for Gaming CPU viability again, I'll make sure it is part of the testing matrix.

I've been reading Anadtech since I was in high school and that has to be my favorite article. I reference that article constantly.It's so hard to find reliable & exhaustive benchmarks of old CPUs. If you could update it every 2 years, I would love you forever!

I read that article and it got me to thinking.. Maybe what is needed is not a direct comparison with new and competing products (which companies may not like..) but rather something stand alone that gets refreshed like your E6400 article. It sets the bar on what the reviewer (and likely most of us) think is needed these days..I know for myself I see a lot steps sideways in the computer industry but it's no longer leaps ahead like it once was.alyarb - Wednesday, January 15, 2014 - link
That would be great. I have a C2Q at 3.7 GHz and a 5850 at 800 MHz. Sure, that is >350W under load, but it still gets the job done at 1080p even in 2014. I have tried and can't justify replacing it all just yet.Similarly I'm not surprised to see Llano is not at the bottom of these charts and is still within striking distance of Kaveri in a lot of the tests. One day I'd like to see the past 8 or 10 years of CPUs all put through the same battery of 2013-2014 tests.
Integration and new features are all welcome, but let's take a look, as performance skeptics, at how far we've really come all this time.

That game will bring that system to it's knees, and it won't be pretty.

Throw in a 760 or a 280x then.. see if it's still brought to it's knees.. Hell a 270/x might do.. it's substantially faster than the 5850 as well.SofS - Friday, January 17, 2014 - link
Careful when comparing older processors regarding the memory subsystem since without the integrated controller they are very sensitive to memory performance or at least my C2Q 9550 @3410MHz seems to be. In my case the upgrade to to a G.Skill F3-12800CL6-2GBXH dual kit I made some years ago was meaningful and some other readers here on similar platforms might find that only upgrading the RAM would give them headroom enough to avoid a whole new system purchase for a while longer. Currently I also own a i7-4800MQ based notebook with dual KHX1600C9S3/8G and while noticeably faster for some cases it does not really enable me to game at higher settings than my desktop system given the GPU being a GTX 765M. Going forward a GPU upgrade to the desktop system is all I am looking for.RussianSensation - Friday, January 17, 2014 - link
Sorry, but you may have a confirmation bias here. You bought new memory expecting the system to perform much faster but years and years of personal ownership of C2D/C2Q systems and online reviews show that it hardly performed faster with faster memory. That architecture in fact performed faster with tighter latency. Your kit doesn't even have 5-5-5-15 timings. C2Q 9550 @ 3.4ghz is a slow CPU compared to Core i7 4770 @ 4.5ghz for gaming. Your memory upgrade may have netted you an extra 2-3% increase on average at best.SofS - Friday, January 17, 2014 - link
Come to think of it, maybe the amount was more important, besides going down to CL6 previously it was 2x1GB instead of 2x2GB. If that is the case then my 765M must be holding the 4800MQ back for gaming or something else is very wrong. Currently the only games I play that do not perform properly at 1080p are Witcher2 and Tomb Raider, probably that has more to do with the GPU than the CPU/RAM tough the real question is if a better next generation mid range GPU would still be able to work properly with them.Albangalo - Wednesday, January 15, 2014 - link
While it's not to do with Kaveri, Tom's Hardware did some articles comparing current cpus with older ones:Intel Ivy vs c2d & c2q: http://www.tomshardware.com/reviews/ivy-bridge-wol...
AMD fx vs k10: http://www.tomshardware.com/reviews/piledriver-k10...
