Kao dodatak na moj post o jačem modelu 4xxx serije, danas je izašla vijest o novim 40nm mobile chipovima. Tj službena objava. Dakle 40nm chipovi se već prodaju.. i to kao modeli 4830 i 4860.

Sunnyvale (CA) - Today, AMD announced two new ATI Mobility Radeon HD 4000-series GPUs for notebooks, the HD 4830 and HD 4860, both built on ATI's new 40nm process technology and both supporting DDR3, GDDR3 and GDDR5 memory support (GDDR5 more than doubles graphics memory bandwidth over GDDR3). The GPUs sport 640 stream processors in a die size that is nearly the same size as the previous mobile near high-end 4670 chip, which had 320 stream processors. Power consumption shows a nearly 50% increase in performance per watt, resulting in a slight overall increase under maximum load, but a near doubling of mobile compute performance to 832 Gflops compared to 4600-series (up from 432 Gflops), and down slightly from 880 Gflops in 4800-series though on less power.

Dakle već su ovi chipovi jako blizu sadašnje 4800 serije, i ne vidim zašto ne bi za mjesec dana izašao i 40nm chip sa 800 sp-a, većim clockom, i boljim performansama - a manjom potrošnjom. Mislim da ću ipak čekati, ako ništa drugo, onda zbog ovoga: "nearly 50% increase in performance per watt".. Dakle ako je 4870-ica i bila jako vruća, novi chip će biti ili cca 50% brži, ili i nešto brži i nešto hladniji.. Ja bih bio sretan sa 30% bržim chipom koji je 20% hladniji npr

Ah, i zaboravio sam da ATI skida cijene 4870-ice sa 200$ na 150$ ovaj tjedan. E sad, ili je novi proizvod blizu, ili samo ratuju cijenama zbog "izlaska" GT250-ice, ali u svakom slučaju još jedan razlog za čekanje
