An "admin" user at RedQuasar forum recently posted some benchmarks of Core i5-4570 and Core i7-4770K 4th generation processors, built on Haswell microarchitecture. What makes these benchmarks different from previous authorized and unauthorized Haswell tests is that they involved production versions of CPUs, and not engineering samples. The "admin" user also posted pictures of production i5-4570 and i7-4770K chips with SR14E and SR147 S-spec numbers.
Both Haswell processors were tested using 3DMark11, AIDA64, Super Pi, Cinebench 11.5 and Fritz Chess Benchmark programs. The "admin" user also ran tests on Core i7-3770K, and made an attempt to run them on Core i7-4770K, overclocked to 4.5 GHz. Overclocked 4770K, even with water cooling, was not stable enough to complete Cinebench 11.5, and running more CPU intensive benchmarks like Prime95 was out of the question. It seems that, like their Ivy Bridge predecessors, Haswell CPUs exhibit the same problem operating at high or very high temperatures when overclocked. Nevertheless, the user was able to receive some results for Core i7-4770K @ 4.5GHz, and they are presented in the table below:
|Benchmarks||Core i7-4770K||Core i5-4570K||Core i7-3770K||Core i7-4770K|
|AIDA64 read||22190 MB/s||20660 MB/s||23247 MB/s||23127 MB/s|
|AIDA64 write||22673 MB/s||20927 MB/s||20704 MB/s||26125 MB/s|
|AIDA64 copy||29739 MB/s||28351 MB/s||24907 MB/s||30651 MB/s|
|Fritz Chess Benchmark||14398||11476||14683||17461|
|Cinebench 11.5 CPU||7.82||6.06||7.88|
|Cinebench 11.5 OpenGL||75.93||68.26||57.74|
Looking at the results, one might say that Haswell's CPU performance is pretty much the same as performance of Ivy Bridge counterparts. Haswell chips are slower at reading from memory, but faster at writing to, or copying data in memory. Ivy Bridge-based 3770K was slightly faster in Super Pi, Cinebench 11.5 and Fritz Chess benchmarks. Haswell CPUs do have much higher graphics performance, up to 31% in Cinebench OpenGL test. Lower, than expected, performance of Haswell parts could be attributed to an early motherboard BIOS, and/or a choice of benchmarks. The 4th generation microprocessors should perform better in other tasks, and especially in programs, utilizing new AVX2 and FMA3 instructions.
