AMD Kaveri Review: A10-7850K, A10-7700K and A8-7600

CPU Performance Continued

AIDA 64 Engineer

AIDA64 Engineer is a streamlined Windows diagnostic and benchmarking software for engineers. It has unique capabilities to assess the performance of the processor, system memory, and disk drives. AIDA64 is compatible with all current 32-bit and 64-bit Microsoft Windows operating systems, including Windows 8 and Windows Server 2012. AIDA64 implements a set of 64-bit benchmarks to measure how fast the computer performs various data processing tasks and mathematical calculations. Processor benchmarks utilize MMX, SSE, XOP, FMA, AVX and AVX2 instructions, and scale up to 32 processor threads. For legacy processors all benchmarks are available in 32-bit version as well.

AIDA 64’s Queen test is a pure multi-threaded x86 CPU test and it shows that Kaveri doesn’t have the strongest CPU part, failing to match Richland and Haswell. This test tends to favour frequency more than cores so it isn’t surprising to see the A10-6800K and Core i3 4330 do so well.

AIDA 64’s throughput tests of ZLib, Hash and AES show a much better picture for AMD CPUs. AMD perform much better against Intel’s Haswell across these tests through only the Hash test shows Kaveri to be faster than its predecessor Richland.

Looking at the floating point unit (FPU) performance and there is a substantial gap between AMD and Intel. Haswell literally wipes the floor clean on the FPU side against both Kaveri and Richland. Furthermore, Kaveri doesn’t do very well against Richland either, losing out to its predecessor in most areas except at the 45W envelope.
