With the arrival of the GeForce GTX 1050 Ti and GTX 1050, the sub-$150 graphics card market is beginning to heat up. AMD is finding itself with a price-performance gorge between the Radeon RX 460 and the RX 470. Citing multiple sources, VideoCardz suspects that AMD is up to something – a new Polaris 10 “Ellesmere” based SKU positioned between the RX 460 and RX 470, referred to either as the “RX 465” or the “RX 470 SE.”
The new SKU is further cut down from the Polaris 10 stack, in a bid to lower TDP below the 100W mark, to around 90W. The chip features 1,792 stream processors across 28 Graphics CoreNext compute units (CUs), out of the 36 CUs physically present on the chip. The RX 470 features 32 CUs, while the RX 480 maxes out all available CUs. AMD is leaving the memory bus untouched. It features 4 GB of GDDR5 memory across a 256-bit wide memory interface, ticking at 7.00 GHz (GDDR5-effective), churning up 224 GB/s of memory bandwidth – double that of the GTX 1050 series. There’s also talk of yet another SKU, with 1,536 stream processors (24/36 CUs enabled), which AMD could position against the GTX 1050 (non-Ti).
A quick trot through 3DMark Fire Strike Extreme and 3DMark Time Spy scores released by a ChipHell Forums user with access to a sample, reveals that stock speeds and 100% power-limit, the 1,792-SP SKU is about 11 percent slower than the RX 470 4 GB in Fire Strike Extreme, and about 11.7 percent slower at Time Spy. It’s expected that should this card outperform the GTX 1050 Ti, AMD could position it competitive yet slightly higher than the US $139 NVIDIA is asking for its card.Sources: ChipHell, VideoCardz
