AMD Richland and Socket FM2 Platform: Computing Performance
Single thread is not obsolete and no multithreaded is not the future. Some tasks benefit more with single thread compared to multithreaded. Other tasks will benefit with multithread. You can think otherwise, but still there will be a mixture of multithreaded and single thread applications in the future.
Actually Haswell with Iris Pro actually competes against AMD's APU offerings by twice the performance. Iris Pro uses eDRAM as a cache for both the CPU and graphics to minimize memory bandwidth bottleneck. APU have huge memory bandwidth bottleneck that restricts its performance.
I am sad to say that Kaveri is not going to be a game changer because of the pathetic performance boost Richland and where Intel is at right now which is about quadruple big leaps ahead of AMD. AMD needs to think about their business model for 80x86. If AMD is also going to develop ARM processors, AMD will not have any money for R&D for both 80x86 and ARM. AMD's CPU business is a lost cause now even though they did well during the Athlon days (1999 to 2006). AMD lost a lot of good engineers since 2006.
Nvidia, VIA & AMD all have quit BAPCo (the sysmark development company) because sysmark 2012 was proven to be rigged in favor of intel platforms.
The reviewer continues the review with very lightly threaded based benchmarks where the performance of the 4 cores on the 6800K were completely ignored & untouched upon, further in, the reviewer showcased performance results of the CPUs in gaming with a discrete graphics card something these APUs were never meant to do as AMD offers less expensive high performance processors without integrated graphics in the form of FX line-up where an FX 8320, AMD's eight core Piledriver based processor costs the same as the Richland 6800K Piledriver based quadcore processor.
This utterly bypasses the most vital selling point of the AMD APUs which is the best in class onboard graphics performance in which The AMD APUs handily beat all Intel processors including the flagship i7 4770K from intel which is more than twice as expensive.
All in all this was a depressingly poor thought out review either out of malicious intent to downplay AMD's offerings and skew the results in favor of intel or out of ignorance, both of which deem this review invalid.
Great review showing that AMD APUs are inferior at single threaded performance and not high end game worthy, heterogeneous computing will benefit Intel as much if not more that AMD because of Intel's Ring Bus.
Thanks for bringing us the Facts, AMD pumpers are full of FUD and excuses but the real truth is that AMD's APUs are pretty much worthless for mainstream productivity and gaming. You're much better off with Intel CPU and discrete GPU that you can add a second GPU for a SLI upgrade when needed without bottle-necking like AMD APUs do.
