AMD Radeon R9 390X Video Card Specifications and Performance Numbers Leak

It appears that AMD isn’t liking the fact that all eyes are on NVIDIA this week during their GPU Technology Conference and released some internal slides to the gang over at VideoCardz on the AMD Radeon R9 390X graphics card! The R9 390X slides just happen to have specifications for AMD’s upcoming flagship GPU along with some performance numbers that show it is up to 60% faster than the AMD Radeon R9 290X that was released in 2013.

Legit Reviews asked AMD if these slides were real yesterday and they quickly responded by letting us know that they were likely fake and that “Theres a reason why we havent acknowledged any product names yet. And were still a bit away from talking about it, let alone launch…” With that in mind, let’s dig in!

The AMD Radeon R9 390X uses the Fiji XT GPU and is said to have 4,096 stream processors and is paired with either 4GB or 8GB of High Bandwidth Memory (HBM) that is said to deliver remarkable memory bandwidth. The slide shows the Radeon R9 390X having the 4096 stream processors running at up to 1050MHz, which is good for 8.6 TFLOPS of compute performance. The original Radeon R9 290X had 5.6 TFLOPS of compute performance, so this is a nice little jump up. The slide also shows the AMD Radeon R9 390X can come with either two 8-pin PCIe power connectors or one 6-pin and one 8-pin PCIe power connectors.

The incredible memory performance is thanks to Hynix HBM technology that uses a memory interface that is a 4096-bit memory interface that should give the 390X around 1.25TB/s of memory bandwidth. VideoCardz says that “earlier plans were to release Radeon R9 390X with 4GB HBM (1GB per stack), but TITAN-X launch made those plans obsolete. Currently AMD is planning to launch R9 390X with 8GB HBM, but 2GB per stack (through Dual-Link). We were told it was a very hard decision to make.”

The AMD Radeon R9 390X is said to support full DirectX 12 features and of course AMD’s own Mantle API along with things like LiquidVR, FreeSync and more.

The slides also show there is an AMD Radeon R9 390X WCE, which stands for water-cooled edition. AMD water cooled the AMD Radeon R9 295X2 8GB video card, so to see another water cooling option on their next-generation flagship GPU doesn’t come as too big of a shock.

On the Radeon R9 390X performance that was leaked it looks like the R9 390X will perform between 50-65% better than the Radeon R9 290X in 4K UDH gaming when looking at four game titles. Will the AMD Radeon R9 390X be able to hang with the NVIDIA GeForce GTX Titan X?

What do we think of the slides? The numbers look a bit high to be fair, but time will tell.
