nForce 790a/750a SLI/MCP78

Mais uma board, desta vez com benchmarks (é certo que um Athlon 64 X2 3600+ não é grande espingarda -menos cache L2 do que os restantes- e afecta muito o CPU Score, mas é um começo).

Também dá a indicação dos nomes finais destes IGP's baseados no core G98 (aceleração H.264 e VC-1, DX10, PCI-Express 2.0, Hybrid SLI, HDMI, etc), Geforce 8100 para o MCP78S, e Geforce 8300 para o MCP78U.
O nome "nForce" não é usado nos IGP's da Nvidia, como sabemos.

A grande vantagem em relação ao RS780 da AMD é o facto de ser single-chip (a AMD precisa da southbridge SB600/SB700, além da Northbridge).

Benchmarks of the MCP78 (DX10 integrated) is leaked on the net.

The test environment is AMD Athlon X2 3600+ , SOYO MCP78, KINGBOX 1G DDR800*2 , WD2500YD, driver 171.03!

The results of 3DMarkxx are as follows :

01: 7072
03: 2598
05: 1461
06(XP): 780
06(Vista): 774

AMD has upper hand in next IGP chipset battle with Nvidia, according to motherboard makers

AMD's RS780 and Nvidia's MCP 78 IGP chipsets are scheduled to go head-to-head in the first quarter of 2008, however, performance of the MCP 78S is reportedly below that of the RS780, while the higher-end MCP 78U is causing issues due to its higher thermal dissipation giving AMD the advantage over the chipset battle, according to sources at motherboard makers.

The RS780 is reported to have 15-20% better performance than the MCP 78S in 3DMark 05 and 06 tests, while the higher-end MCP 78U cannot function normally with the original passive northbridge heatpipe due to the higher core frequencies of the graphics engine. Adopting a larger heatpipe or fan will cause costs to rise significantly, pointed out the sources. Nvidia is still struggling with the problem, they added.

Additionally, motherboard makers have not yet taken delivery of MCP 78 chipset supplies, which means that the original launch schedule of motherboards might have to be postponed back to the end of January or beginning of February, noted the sources.

On the other hand, motherboard makers have already finished preparations for their RS780 motherboard launches and will be ready to ship in January 23 next year.

AMD has also fixed an issue with the SB700 southbridge caused by a malfunction of the internal clock generator. Although motherboard makers will need to add an external one to solve the problem for now, AMD has notified its partners that the issue will be fixed in an updated SB710 chipset, added the sources.

Nvidia declined to comment on this report saying it cannot comment on unannounced products. AMD did not respond by the time of publication.
