Default [TPU] HD 4670 Crossfire Outperforms HD 4850
Quote:
Pre-release 3DMark tests show that two Radeon HD 4670 graphics cards in Crossfire multi-GPU mode outperforms a single Radeon HD 4850 card. The HD 4670 cards score just a little above the HD 4850 in three tests that include 3DMark06 in Shader Model 2.0 mode, the same benchmark in SM 3.0 mode and 3DMark Vantage.

The cards scored 54xx 3DMarks in SM2.0 and 65xx 3DMarks in SM3.0 tests, a 4850 on the same test-bed produced 49xx and 57xx respectively. With 3DMark Vantage, the Crossfire setup churned out 7300, with the single HD 4850 just 100 points behind at 7200. These scores can be attributed to the raw texturing power the HD 4670 cards have despite memory bandwidth advantage staying with the single HD 4850. Indications are that the HD 4650 won't scale as well since (at least reference models) lack hardware Crossfire.

Interesting... But even so, they only beat the 4850 by a small margin--couple that with the likely higher power requirements (I'm only guessing) and a required compatible mobo with a second x16 PCI-E (or x8 PCI-E 2.0) slot and it doesn't seem that worth it. I was kinda hoping to see how a single card performs though...wonder why the first review (I've seen) is for a dual-card setup.

But TBH, all they showed was a single graph, I'm not too convinced yet.

So this means that some OEM is probably going to introduce a HD4670X2!!!!!

I'm going take a stab at the $100 range. Which means for $200 you get HD4850 like performance with the added enjoyment of crossfire driver problems, heat and non-upgradability.
