Testbed Configuration and Testing Methodology
We tested all three above described Core i3 processors from the 3000-series. They will be competing against previous generation Core i3 CPUs on Sandy Bridge microarchitecture as well as a few other products. To complete the picture we also included the junior Core i5 models. I am sure that many of you are wondering whether the new generation top Core i3 processors will be able to compete successfully against older quad-core Sandy Bridge based products.
Core i3 processors fall into a very attractive price range. This segment is also heavily populated by products from AMD – the company that has been focusing on affordable and entry-level processors lately. Therefore, we also included AMD FX-6200 and AMD FX-4170 processors with similar price tags. AMD Lynx platform may also fall into the same price range, so the AMD A8-3870K processor will also be one of the testing participants this time.
As a result, we put together test platforms with the following hardware and software components:
- AMD A8-3870K (Llano, 4 cores, 3.0 GHz, 4 MB L2, Radeon HD 6550D);
- AMD FX-6200 (Zambezi, 6 cores, 3.8-4.1 GHz, 8 MB L3);
- AMD FX-4170 (Zambezi, 4 cores, 4.2-4.3 GHz, 8 MB L3);
- Core i3-2125 (Sandy Bridge, 2 cores + HT, 3.3 GHz, 3 MB L3, HD Graphics 3000);
- Core i3-2130 (Sandy Bridge, 2 cores + HT, 3.4 GHz, 3 MB L3, HD Graphics 2000);
- Core i3-3240 (Ivy Bridge, 2 cores + HT, 3.4 GHz, 3 MB L3, HD Graphics 2500);
- Core i3-3225 (Ivy Bridge, 2 cores + HT, 3.3 GHz, 3 MB L3, HD Graphics 4000);
- Core i3-3220 (Ivy Bridge, 2 cores + HT, 3.3 GHz, 3 MB L3, HD Graphics 2500);
- Core i5-2320 (Sandy Bridge, 4 cores, 3.0-3.3 GHz, 6 MB L3, HD Graphics 2000);
- Core i5-3330 (Ivy Bridge, 4 cores, 3.0-3.2 GHz, 6 MB L3, HD Graphics 2500).

For our tests of the AMD FX-6200 and AMD FX-4170 based systems we installed KB2645594 and KB2646060 OS patches.
Intel Core i3-3225 processor didn’t participate in the tests performed in a system with a discrete graphics card, because its computational performance is identical to that of the Intel Core i3-3220 working at the same clock frequencies.
