Recently, HP announced its latest line of desktop PCs, on HP’s product pages for its new desktop aren’t active but Techpowerup speculate on what the R9 380 could be. The new R9 380 might be a new re-branded R9 285, or be based on its “Tonga” silicon, which physically features 2,048 stream processors based on Graphics CoreNext (GCN) 1.2 architecture, and a 384-bit wide GDDR5 memory interface.
Despite the chance it will be re-branding from “Tahiti” based product would be suicidal for AMD. According to GCN, the predecessor “Tahiti” lacks a lot of architecture features compare with “Hawaii” and “Tonga”. Tahiti has been stop be in AMD radar for optimisation for games, and some new features such as; FreeSync and XDMA CrossFire. The R9 380 might getting 2,048 stream processors, and its full 384-bit GDDR5 memory interface then it will definitely be an OEM product and it will the stepping stone for AMD to be succeeding R9 400 series.
According to AMD’s next-gen lineup there are few re-branding across the line-up, with only one genuinely new silicon. “Tonga” could drive the pair of SKUs that directly succeed the R9 270 and R9 270X; “Grenada”, which is a refined version of “Hawaii”, will drive the SKUs that succeed the R9 280 and R9 280X; while the new “Fiji” silicon, with its 4,096 stream processors and a fancy 640 GB/s High Bandwidth Memory (HBM) interface, could drive the SKUs that succeed R9 290 and R9 290X.
Many must awaits the new R9 390 and R9 390X, it seem AMD going releasing R9 400 series instead of R9 390 or R9 390X.
