Notes
Another case of testing from scratch. We've used an ASUS Crosshair V motherboard flashed to the latest 1605 BIOS. We made sure that Windows 7 had all relevant hotfixes in place. It makes implicit sense to compare the Piledriver-based FX-8350's performance to Bulldozer's FX-8150. Adding some more AMD spice, a six-core Phenom II X6 1100T, based on Thuban technology, gives AMD's new architectures a run for their money.
Intel's four-core 'i5-3570K has already been identified as the natural competitor to FX-8350. It loses out in core count but ships with integrated HD 4000 Graphics. We've also included the last-gen Core i5-2500K and, shipping either side of the £150 price point, the Core i7-3770K and Core i3-3225 offer more context.
Want to know how well some of the above-mentioned chips perform in a Windows 8 environment? Stay tuned, we'll be providing all the answers in a forthcoming review.
