Frequencies, performance and design in details
Ahead of the launch, scheduled for April 8th, the full press deck for the upcoming dual-GPU AMD Radeon R9 295X2 graphics card has found its way online. The slides confirm the earlier details specifications but also adds clock details, performance details as well as some other details regarding the hybrid liquid+air cooler.
Codename "Vesuvius", the dual-GPU Radeon R9 295X2 will be based on two AMD 28nm Hawaii GPUs featuring full 2816 Stream Processors, 176 TMUs, 64 ROPs and 512-bit GDDR5 memory, per GPU. The chips are interconnected via PLX PEX8747 PCI-Express 3.0 x48 bridge chip and pack 8GB of GDDR5 memory, 4GB per GPU. Each of the GPUs will be clocked at up to 1018MHz while memory will end up clocked at 5.0GHz. In case you are wondering, the R9 295X2 is 30.7cm long and due to the hybrid cooler design, takes only two slots.
The outputs on the back include four mini-DisplayPort 1.2 and single DVI output.
The deck slides also reveal some details regarding the VRM design which appears to be a 12-phase one which draws power from two 8-pin PCI-Express power connectors. The maximum TDP is set at 500W, which suggest that AMD is pushing those two 8-pin PCI-Express power connectors quite hard and this one will need a quality PSU with strong +12V rail.
The slide deck also reveals some more details regarding the hybrid liquid+air cooler which was apparently co-developed by AMD and Asetek. Asetek has been around for quite some time and had some impressive water-cooling solution so the AMD choice does not come as a surprise. The hybrid cooler features a pair of blocks with integrated pumps on the GPUs and ran to the separate 64mm thick (38mm without the fan) 120mm radiator/reservoir unit. The center placed fan on the graphics card will take care the cooling of the VRM, memory and PCIe bridge chip.
The general performance should put the R9 295X2 at around 60 percent faster than the R9 290X in 3DMark Firestrike benchmark, which is what we expected in the first place.
All we need now is the precise price and availability date but we guess we will have to wait for the 8th of April for those. You can check out the full press deck via link below.
