AMD Bulldozer sample vs Intel Core i7-990x in SLI test

Posted: 30 Jun 2011 12:51 PM PDT

The Czech IT website PCTuning has run a test on AMD’s 990FX chipset, with an alleged sample of the new FX architecture based Bulldozer processors. Here, the gaming performance was with a Intel Core i7-990x -SLI configuration and the current flagship – AMD Bulldozer.

Intel Ivy Bridge Release Date

Both the “Bulldozer” sample as well as the Intel Core i7-990x CPU was overclocked to 4GHz. While the Core i7-990x has six cores (12 threads) with normally 3.46 GHz clock, the exact specifications of the pre-set clock speed of Bulldozer CPU from AMD are not known, but it should have been given by 3.2 GHz (3 core Turbo, 7 GHz). One can assume that the same engineering sample was used here, which our colleagues have already overclocked it to 4.6 GHz with air cooling, as was described in the below video. In that sample, it should be a FX CPU with eight cores, four modules and multiplier-free (fully unlocked).

Vermeintliche „Bulldozer

As the chart shows, the AMD and the Intel, team with four Nvidia GeForce GTX 580, but Intel has a slight lead above Bulldozer in all of the gaming benchmarks. At Dirt 2, 2 and Resident Evil 5 Hawx Intel’s advantage is more pronounced. The author of the article points out, however, that the performance of the AMD Bulldozer FX-samples do not necessarily reflect the final chips. We can see the the final results once AMD Bulldozer is released in October. There is also the possibility that more mature drivers can come and the performance can still improve.

Given that the AMD sample is beaten by the current fastest Intel processor, the results just not seem bad. But in the fourth quarter, Intel will be using the “Sandy Bridge-E” to bring out new high-end CPUs, against which AMD FX CPUs will be having serious competition. This test has been carried on with B1 stepping of AMD Bulldozer and now B2 stepping has come. We have also reviewed the performance of B2 stepping of AMD Bulldozer which gives a better performance than B1 stepping AMD Bulldozer.

APU + AMD GPUs detailed discrete combinations

Detailed AMD Dual Graphics Technology

Earlier this year it was revealed on AMD Dual Graphics Technology , which combines the graphical power of integrated graphics in the APU Fusion with its low-end GPUs to achieve a performance close to that of a mid-range GPU. While last month breakdown of the drivers from AMD leaked some of the nomenclature about these combinations . Now VR-Zone claim to have the official data from AMD. But unfortunately they have removed the post from their site ( Thought of mentioning it here).

AMD Dual Graphics Technology is available on the APU – AMD IGP Llano A Series and not available in other models (G Series, E Series, etc). Below we have compiled a table of all possible combinations of low-end AMD GPUs support and AMD APU Llano A Series:

Table for desktops

Table equipment “All in 1″

Conclusions

Some preliminary reviews of the desktop version of Llano confirm that the classifications are meaningless, for example the combination Llano A8 with its IGP Radeon HD 6550D + discrete GPU Radeon HD 6670,which is called Radeon HD 6690D2, performs very close to the AMD GPU Radeon HD 6750 and so the performance is consistent with its nomenclature.
