Microstuttering tests on ATI Radeon HD 4870 X2

LOL, madshrimp says the exact opposite about Crysis with their setup.

At 1920x1200 we see a ~5fps drop for both cards, but numbers are still acceptably high. We did notice a lower min. FPS on the HD4870X2, suspecting that this was maybe due to micro-stuttering we manually measured the FPS with FRAPS in-game in the same Alien Spaceship level, but we didn’t notice any stuttering, the 23 fps drop was early on the level.

TestBed from madshrimp review:
Intel Core 2 E8200 @ 2.66Ghz
Cooling Scythe Ninja 2
Mainboard MSI P45 Platinum
Memory 2 * OCZ 1Gb PC2-6400

Testbed computerbase:
Intel Core 2 Extreme QX9770 (overclocked by multiplier to 4 GHz quad-core)
Noctua NH-U12P Noctua NH-U12P
Asus P5E3 Deluxe WiFi-AP main board Intel X38, BIOS-Version: 1104 test for Crossfire systems
XFX nForce 790i Ultra (Nvidia nForce 790i, BIOS-Version: 811N1P01_Beta) für SLI-Systeme
2x 1024 MB G.Skill DDR3-1600 (7-7-7-18)
2x 1024 MB Patriot DDR3-1600 (7-7-7-18)

Clearly 2 different testbeds. Also, we know that stutter can be induced and can be the results of something other then the GPU. Another thing, these "stutter charts" have no legend nor does the creator explain how each plot on the chart is obtained. Making these type of charts vague. Leaving it up to the reader to make assumptions of how it was obtained or, some validating it without any rudimentary information of where the plots on the chart come from.
