Intel Pentium 20th Anniversary Edition G3258 CPU Review

CPU by leeghoofd @ 2014-06-16

Intel announced earlier this year the Haswell refresh lineup together with the release of their latest mainstream chipset, the Z97. This refresh release was overshadowed by the eagerly awaited high end K SKU Devils Canyon and the low end 20th Anniversary Pentium processor; especially the latter is a very interesting product as it now sports a fully unlocked multiplier and retails at an insane low price. We have to thank the boys from Denmark Zzolio and Riska which allowed us to spend some time with their G3258 Pentium ES processor.

Test Setup and Methodology

Our mainboard during the test suite is the Gigabyte Z97X SOC Force. We flashed the latest F6 bios which is fully Pentium compatible; earlier versions did not allow multiplier, nor ring bus speeds adjustments. To keep things aligned we are still using the dual channel Corsair Dominator 1600MHz C8-8-8-24 kit. Even though the Pentium Anniversary edition is only certified for 1333MHz memory speeds we opted to test all the processors at equal ram clocks of 1600MHz.

For our tests we use single as multi-threaded benchmarks to discover the performance of the tested processors. For the 3D tests we are using a 7970HD discrete graphics card, which is still a solid mainstream card.

2D tests used:

  • Superpi32m (single threaded)
  • Wprime 32 & 1024 (single and multi-threaded)
  • Cinebench R10 (single and multi-threaded)
  • Cinebench R11.5 (single and multi-threaded)
  • Fritz Chess benchmark (multi-threaded)

3D synthetic tests used:

  • Futuremark 3DMark 11
  • Resident Evil 6 Benchmark
  • Catzilla v1.2 720P and 1440P setting

3D Gaming test (resolution 1920 x 1080) used:

  • Bioshock Infinite at High and Ultra preset
  • Tomb Raider at High and Ultra preset
  • Sleeping Dogs at High and Ultra preset
