Possible Look at Specifications and Performance for AMD's Radeon R9 390X

[[Coi] Mr.CLuBBeR]

A potentially beastly card in the making

Go ahead and apply the standard disclaimer about leaked specs not being verified or official, because that's certainly the case here. Disclaimer aside, we hope that unconfirmed specifications of the AMD's forthcoming Radeon R9 390X graphics card turn out to be accurate, because if they are, it's going to be a potent part that's up to 60 percent faster than AMD's Radeon R9 290X.
The folks at Videocardz asked their source if he could share additional information about AMD's new flagship graphics card, and to the site's surprised, he responded in kind with a few more goodies to digest. One of those goodies is that AMD scrapped plans to run with 4GB of High Bandwidth Memory (HBM) Gen1 (1GB per stack) after Nvidia unveiled its Titan X graphics card. Now the plan is to release the Radeon R9 390X with 8GB, but Gen2 (2GB per stack), on a 4,096-bit bus (1,024-bit per stack). That should give the card around 1.25TB/s of memory bandwidth.
The GPU is said to be a 28nm Fiji XT part with 4,096 unified cores and 256 Texture Mapping Units (TMUs). There's no mention of ROPs or core clockspeed, though the boost clockspeed is reportedly 1,050MHz. Other specs include a 1,250MHz memory clock, 8.6TFLOPS of compute performance, and either a 6+8 pin or dual 8-pin PCI-E configuration.
There's also a performance slide that was leaked, and if it's accurate, performance will be up to around 1.65 times that of the Radeon R9 290X in 4K gaming.
Reports from elsewhere on the web have the card debuting at around $700, which is also unconfirmed.
