We're now just over a month away from the arrival of Intel's Lynnfield processors, according to the rumor mill's most precise estimates. And surprise, surprise, a Chinese website has already posted a full review of two Lynnfield parts—a "Core i7-870" and "Core i5-750."
The former will supposedly run at 2.93GHz with a top speed of 3.46GHz for individual cores, thanks to Turbo Boost. The Core i5-750, meanwhile, should run at 2.66GHz and lack support for Hyper-Threading (so you'll only get four threads with your four cores).
How do these puppies perform? We can't vouch for PConline's methodology or results, especially since Intel hasn't even announced these CPUs yet. That said, the site's numbers span a decent cross-section of tests, from WinRAR, Cinebench, and TMPGEnc to Call of Duty: World at War and Far Cry 2. A cursory look shows the Core i7-870 outperforming the existing Core i5-920 overall, with the i5-750 lying between the i7-920 and the Core 2 Quad Q9550. The i5-750 looks to be the most power-efficient of the four.
This leaves the question of how Intel will price these new CPUs. Digging up a slightly stale report from April suggests the Core i5-750, if it indeed exists, may land just below the $200 mark. The i7-870, meanwhile, might cost roughly the same as the Core i7-920.
