ATI Radeon HD 4870 X2: another slap in the face for NVIDIA?

AMD also announced the "little brother" of the dual-core VGA, the ATI Radeon HD 4850 X2.

AMD's press release calls the ATI Radeon HD 4870 X2 the "world's fastest graphics controller" with noble simplicity: it supports this claim with a 3DMark06 score (17743), which is considered the highest value ever achieved in the test program, of course excluding the various CrossFire and SLI solutions. . We have discussed the R700 several times in the columns of our website, so our regular readers can be aware of the card's parameters and the tests so we will now avoid repeating them.

The "emergence" of the ATI Radeon HD 4850 X2 could not have unexpectedly affected our loyal readers, since slowly for a month it was already possible to know (guess) that the HD 4870 X2 will not remain an "orphan". AMD associated the two RV770PRO GPUs with 2 GB of GDDR3 memory, and the suggested retail price of this VGA was set at 399 US dollars. The HD 4850 X2 will start shipping in September.
