New two-, three- and six-core AMD CPUs are 100MHz faster, get benchmarked extensively

by 6 comments

AMD is launching a few slightly upgraded CPUs. The first is a new six-core AMD Phenom II X6 1100T, which is clocked 100MHz higher than its predecessor. And from the Island of Misfit Toys come the new X3 and X2 Athlons, which are getting a similar speed bump – and in the spirit of holiday gift-giving, the new X3 is priced the same as the older, slower X3…

The AMD Athlon II X3 455 is clocked at 3.3GHz, up from 3.2GHz of the 450, and costs the same. The Phenom II X2 565 got a 100MHz bump too (to 3.4GHz) but it costs $10 more than the previous model.

Both these X2 and X3 CPUs are actually quad-cores with one or two defective cores. If you’re really lucky, those cores might just be disabled but otherwise working cores, opening up the possibility for getting one more core for free (again, if you’re really lucky).

The AMD Phenom II X6 1100T enjoys a speed bump of 100MHz as well – it’s clocked at 3.3GHz (up from 3.2) and the maximum Turbo Core (AMD’s Turbo Boost) frequency is 3.7GHz (up from 3.6). The 1100T is a good $30 pricier than the 3.2GHz 1090 though.

Check out the performance benchmarks of these CPUs – the six-core X6 1100T struggles against a quad-core i5 when the task at hand is not much multithreaded, but on proper multi-threading tests it pulls ahead, even breathes down the neck of some i7 processors.
