AMD unofficially confirms Radeon Flagship – R9 390X - Launches at Computex

AMD unofficially confirms Radeon Flagship – R9 390X - Launches at Computex

Over at GDC AMD did not announce the pending Radeon  R9 390X flagship just yet as many had hoped - then again, they kind of did. The Fiji XT based monster was apparently powering the Showdown demo on the Oculus Rift Crescent Bay. So we know for sure they are having a bit of volume with the engineering samples.

How do we know this ? Well, it helps that AMD employees use Twitter:

The R9 390X graphics card will be based on AMD’s upcoming flagship Fiji XT GPU. The graphics card will be the first ever to feature stacked high bandwidth memory, or what you guys know as HBM. If we compile a thing or two in a chart, this is what the summer of 2015 will offer us in the enthusiast range (all speculation of course):

  Stream Processors Memory Memory Bandwidth Memory Interface GPU Boost  Compute Performance
AMD Radeon R9 390X Fiji XT 4096 4GB HBM 640 GB/S 4096-bit HBM ~1017Mhz ~8.0 TFLOPs
Nvidia GeForce Titan X GM200-400 3072 12GB GDDR5 336 GB/S 384-bit GDDR5 ~1216MHz 6.0~7.0 TFLOPs
AMD Radeon R9 290X Hawaii XT 2816 4GB GDDR5 320 GB/S 512-bit GDDR5 1000Mhz 5.6 TFLOPs
Nvidia GeForce GTX 980 2048 4GB GDDR5 224 GB/S 256-bit GDDR5 1216Mhz 4.6 TFLOPs

It is rumored that Fiji XT will get 4096 stream processors with 4GB of HBM VMEMORY. This is stacked memory and therefor the bus width is gigantic. In fact that would be a 4096-bit memory interface. The GPU memory interface is indicated to operate at 1.25Gb/s data-rate (1.25GHz effective DDR frequency) and delivers enormous 640GB/s memory bandwidth. The R9 390 series will be cooled with the help of an Asetek liquid  cooler. Meanwhile bad news as to the release date, it now is said that this product will be announced not anytime sooner than Computex, which is June 2015.

“We are confident that as we get into the second half of 2015 with the launch of that new graphics product, we will gain back the market share which is low from my standpoint and historically,” said Devinder Kumar, chief financial officer of AMD. “We need to be significantly higher than where we are right now.”

I wonder how efficient this new card is on power consumption? Hopefully it will not serve as an room space heater like their previous cards.

Can AMD put HBM RAM on the 290X?
