Test System And Benchmarks

Gaming Shoot-Out: 18 CPUs And APUs Under $200, Benchmarked
By

Testing LGA 1155-, Socket AM3-, Socket FM1-, and Socket FM2-based CPUs requires four different platforms. We're using the same memory, hard drive, and graphics card on all four to eliminate as many variables as possible.

We're using Gigabyte's Z77X-UP7 for our LGA 1155-based platform. This is the company's flagship offering for that processor interface. The similar (but lower-priced) Z77X-UP5 earned our Recommended Buy award in Six $220-280 Z77 Express-Based Motherboards, Reviewed, so the -UP7 appears to be a great choice for our testing.

For the Socket AM3+-based system, we're using Gigabyte's 990FXA-UD5 motherboard. This product achieved the highest CPU overclock in our Five $160 To $240 990FX-Based Socket AM3+ Motherboards comparison, and distinguishes itself with true four-way SLI support.

Our Socket FM1-based platform is Asus' F1A75-V Pro, a board that demonstrated excellent overclocking potential in Professional Help: Getting The Best Overclock From AMD's A8-3870K.

Finally, the Socket FM2-based platform is represented by Asrock's FM2A85X Extreme6. This motherboard garnered our Tom's Hardware 2012 Approved award in Six Socket FM2 Motherboards For AMD's Trinity APUs thanks to a combination of high performance and low price.

As for the graphics card, we chose one of the fastest single-GPU boards available, MSI's GeForce GTX 680 Lightning. Our goal is to isolate CPU performance, so we made this choice with the intention of de-emphasizing GPU bottlenecks.

We're testing the 18 most notable CPUs under $200, including some previous-gen products (the Core i5-2500K costs more than $200, but it's included for comparison purposes) to gauge the improvements that have been made. The Athlon II X4s didn't make it because they employ the same micro-architecture and cache configuration as the Llano-based APUs, so they'd be redundant. AMD's A8-3870K processor accurately represents the performance of a 3.0 GHz Athlon II X4.

The Corsair Vengeance memory kit we used is rated at 1000 MHz with 10-10-10-27 2T timings using a built-in XMP profile, and we set it to that speed whenever possible. Due to limitations on certain platforms, we dropped the modules to 933 MHz on the Pentium G860, and 800 MHz at 9-9-9-24 2T timings on the Athlon II X3 450.
