AMD's Six-Core Phenom II X6 1090T & 1055T Reviewedby Anand Lal Shimpi on April 27, 2010 12:26 AM EST
The Performance Summary
At $199 and $285 the obvious comparison points are Intel’s Core i5 750 and Core i7 860. We’ll dive into the complete performance tests in a bit, but if you’re looking for some quick analysis here’s what we’ve got.
Single threaded performance is squarely a Lynnfield advantage. Intel’s quad-cores can turbo up more and Intel does have the advantage of higher IPC.
|Phenom II X6 vs. Intel's Lynnfield Processors|
|Cinebench R10 (Single Threaded)||Cinebench R10 (Multithreaded)||3dsmax r9||x264 HD - 2nd Pass||Left 4 Dead|
|AMD Phenom II X6 1090T||3951||18526||13.7||28.5 fps||127.2 fps|
|AMD Phenom II X6 1055T||3547||16268||12.7||25.1 fps||111.5 fps|
|Intel Core i7 860||4490||16598||15.0||26.8 fps||131.0 fps|
|Intel Core i5 750||4238||14142||13.4||21.0 fps||130.0 fps|
Highly threaded encoding and 3D rendering performance are obviously right at home on the Phenom II X6. The 6MB L3 cache and lower IPC does appear to hamper the Phenom II X6 in a couple of tests but for the most part if you need threads, the X6 is the way to go.
Applications in between generally favor Intel’s quad-cores over the Phenom II X6. This includes CPU-bound games.
None of this should be terribly surprising as it’s largely the same conclusion we came to with the Athlon II X3 and X4. If you run specific heavily threaded applications, you can’t beat the offer AMD is giving you. It’s the lighter or mixed use workloads that tend to favor Intel’s offerings at the same price points.
