Tried it: AMD Radeon HD 7870/7850 - dangerous pit bulls

test Results

Synthetic programs, coding:

According to the schedule, we start with 3DMarkas as usual. Although the release of the Vantage dates back quite a few years, it didn’t bother the fresh GCN models, and the Pitbulls, uh, that is, Pitcair, have already begun to work hard. The graphs will be based on the base clock performances, the tuned clock performance of each card can be evaluated by everyone. So the HD 7870 clearly surpasses the HD 6970 in both scores, while the HD 7850 was first a few hundred points behind the overall score compared to the HD 6850, but at the GPU score he already wins. In terms of GeForces, the HD 7870 beats the GTX 570, and the HD 8750 performs at about the same level as the GTX 560 Ti.

Under 3DMark11, the picture changes to the extent that Pitcair's power continues to grow. At least for the HD 7870 anyway, as he beat a good 700 points for the HD 6970 in Permormance mode and 150 for the Extrme. The HD 7850 P beats the HD 6950 nicely when running, but in Xtreme mode it gets knocked out in a close battle. The 7870 beats the GTX 570 ugly and is close to the GTX 580, and the 7850 confidently beats the GTX 560 Ti.

Under the Unigine Heaven Benchmark, Pitcairn’s significantly kneaded testing ability is demonstrated. The HD 7870 point captured the GeForce GTX 580, and the HD 7850 managed to beat the GTX 570. The comparison to the previous generation is almost pointless, even the 7850 is beating the HD 6970 loosely. This is a fresh and very favorable feature for Pitcairn for future games.

Regarding video conversion, we’ve already said in the 7900 series that the capabilities of the new architecture have improved a lot compared to the previous generation. Although GeForce has not yet been able to catch up in speed, in the program we use, severe seconds have been carved compared to the VLIW4 models. Well, Pitcairn was a few seconds behind Tahiti, so it deserves praise.
