pensava ke a 4870x2 vinha com 2 giggas de ram
Vai dar ao mesmo:
3600Mhz a 256Bits tem exactamente a mesma largura de banda que 1800Mhz a 512Bits.
E os timings, não contam?
Para a largura de banda? não.
Contam é para as latencias - ciclos de espera entre escrita de dados, e disponibilização desses dados para leitura.
Para a diferença NA PERFORMANCE entre uma largura de banda obtida com 512x1800 vs 256x3600, não é?
Para a diferença NA PERFORMANCE entre uma largura de banda obtida com 512x1800 vs 256x3600, não é?
256Bit bus clocked at 2000mhz is just as fast as a 512Bit bus at 1000mhz

Radeon HD 4000 Series in June?
If German site called HARTWARE.NET is to be believed, AMD’s next generation of Radeon graphics cards could be released as early as June this year. According to the site, an AMD roadmap it has managed to acquire shows seven upcoming cards, the Radeon HD 4450, Radeon HD 4470, Radeon HD 4650, Radeon HD 4670, Radeon HD 4850, Radeon HD 4870, and Radeon HD 4870 X2. The 4400 cards will apparently feature 40 stream processors, the 4600 cards will have 240 and the 4800 cards will have 480 (with the X2 featuring 960 overall, 480 on each core). There is no firm indication of clock speeds, but the 4600 and 4800 cards are expected to run somewhere between 800MHz and 1050MHz depending on the model, ranging from 128MB of DDR2 to 1GB of GDDR5 memory. However, there are no details of which cards will be released when, just that the initial launch could be sometime in June. Remember that this information might not be completely reliable and shouldn’t be interpreted as firm facts.

Ca para mim... eu acho que a AMD anda a deixar os outros passar a frente para depois ela passar por cima
E ca para mim vem aí bombinha ^^
R700 based on shared memory architecture
R700 architecture is different from R680 as it posesses the ability for the 2 RV770 GPUs to address a common pool of memory. R700 could possibly the first card to run Crysis flawlessly. Also the recent specs leaked on Radeon HD 4000 series are fake according to them.

Newest picture of RV770.
The ram's position and power supply part of RV770 are very different from RV670.
