Chinese website, ChinaDIY, has somehow managed to get hold of an unannounced Intel part, an engineering sample of the Intel Core i7-4770K processor, which is based on the soon-to-be-released Haswell architecture.
The benchmarks show that the gains are mostly derived from a reworked memory controller plus new AVX2 and FMA3 instructions. The biggest gains, compared to the i7-3770K, are in MediaCoder and Cinebench. As for the significantly upgraded graphics subsystem, 3Dmark 11 scores appeared to be roughly similar which leaves us to believe that one should take the figures with a pinch of salt.
The parts are likely to be genuine but we believe instead that it is too early for a call given that other unforeseen variables might impact on performance. These include a non-final BIOS, non-optimised benchmark applications and drives and early motherboard/chipset revisions.
Intel will launch Haswell (and scores of SKUs as well components and devices from partners) at a special event in Computex early next month and archrival AMD is likely to disclose more about Kaveri, its next generation high end part, soon after.
