AMD Rx 300 Series Specs revealed

Some very legitimate looking AMD Rx 300 series specs have been making their runs around the rumour mill, which include a Dual GPU monster with over 8000 GPU cores, not quite over 9000 but considering the current R9 290X has only 2816 GPU cores is a considerable amount of GPU horsepower.

Remember guys that these are rumours and should be considered as such.

A lot of the series will be re-releases of some of AMD's current line-up, with the R9 285 becoming the R9 370 and the AMD R9 290 series becoming the R9 380 series. With this in mind we can easily say that these GPUs will not have much improvements apart from clock speed bumps and very minimal changes in terms of power consumption.

The most interesting change in AMD's R9 390 series, apart from the massive GPU core count is the change over to High Bandwidth memory, which will give higher performance and lower power consumption than GDDR5 memory. The move to HBM will be a very welcome change as 4K become more and more popular and ever more affordable. Hopefully the GCN 1.3 Architecture will provide us with some efficiency improvements as the AMD R9 290 series was already rwell known for it's high temperatures and large power consumption.

Other AMD R9 300 series rumours

AMD had recently told a disgruntled former owner of Nvidia's GTX 970 on Facebook that they are "putting the finishing touches on the 300 series" of GPUs. They have given no release date for the upcoming series of GPUs. This is the first time AMD has officially spoken about the Radeon Rx 300 series of GPUs, so let's hope this means they will be coming soon.

"We don't have an official date to share just yet but the second we know, we will definitely announce it on Facebook."

"We're still putting the finishing touches on the 300 series to make sure they live up to expectation. Can't wait to reveal them though. We're pretty excited."

AMD's next Generation GPU, or rather the AMD R9 390X will be using AMD's Fiji GPU core which will be using the next Generation of AMD's GCN architecture. GCN 1.3.

Thanks to Zauba, a database for import export data, we can now see that AMD have been sending Fiji PCBs around the world. The C880 PCB is believed to be a finalized PCB design for the R9 390 series of GPUs, with the Fiji XT core being the GPU core used in the R9 390X.

The most interesting leak so far for the AMD R9 390x is these potential specifications. Data from SiSoft Sandra has appeared on their online database regarding a future unknown AMD high-end GPU, giving a core count and potential clock speeds.

There are two cards which are of particular interest, firstly a card with 4096 stream processors at 1000MHz with 4GB of VRAM. This card is thought to be the R9 390X. The Second GPU has 3520 stream processors at 1050MHz and is thought to be the R9 390. Links to these results are here and here.

The sheer amount of stream processors in these units compared to the R9 290X and R9 290, which were 2816 and 2560 stream processors respectively, means that these GPUs should perform much better than their predecessors. Even after the bump in core count there is also the architectural improvements to consider like the improved tessellation performance and memory efficiency as seen in AMD's Tonga based R9 285.

AMD do not just need to beat the Maxwell based GTX 980 here, but AMD need to release a product which will compete with "Big Maxwell" which is expected at some point this year. Remember guys, in terms of core count and die size the GTX 980 is really a GTX 770 or 680 replacement. What would Nvidia's Maxwell be like when scales up to the core count/ die size of a GTX Titan or 780Ti?

Things are looking good for the future of GPUs.
