As for the real world performance drop, as we’ll see it’s around 7%.
Finally in the middle, workloads that are front-end or back-end bound will see a much smaller drop since those units haven’t been cut-down at all, leading to just a 5% performance drop. At the other end of the spectrum, in a shader-bound scenario, the combination of the reduction in shader hardware and clockspeeds is where the R9 Fury will be hit the hardest, as its total FP32 throughput drops from 8.6 TFLOPs to 7.17 TFLOPs. In the best case scenario for the R9 Fury of a memory bandwidth bottleneck, it has the same 512GB/sec of memory bandwidth as the R9 Fury X. On the other hand the memory clock remains unchanged at 500MHz DDR, for an effective memory rate of 1Gbps/pin.Īll told then, on paper the performance difference between the R9 Fury and R9 Fury X will stand to be between 0% and 17% that is, the R9 Fury will be up to 17% slower than the R9 Fury X. The reference clockspeed for the R9 Fury is a flat 1000MHz, a 5% reduction from the R9 Fury X. With Fiji topping out at just 4GB of memory in the first place – one of the drawbacks faced by the $650 R9 Fury X – cutting back on memory here to a smaller capacity is not a real option for AMD, so every Fiji card will come with that much memory.Īs for clockspeeds, R9 Fury takes a slight trim on the GPU clockspeed. All Fiji-based cards, including the R9 Fury, will be shipping with a fully enabled memory subsystem, meaning we’re looking at 4GB of HBM attached to the GPU over a 4096-bit memory bus.
AMD RADEON R9 FURY FULL
This in turn ends up being the full extent of the R9 Fury’s disabled functional units, as AMD has not touched the front-end or back-end, meaning the number of geometry units and the number of ROPs remained unchanged.Īlso unchanged is the memory subsystem. The Fiji GPU in the R9 Fury ends up having 56 of 64 CUs enabled, which brings down the total stream processor count from 4,096 to 3,584. As is usually the case for these second-tier cards, the R9 Fury features both a GPU with some functional units disabled and a slightly reduced clockspeed, allowing AMD to recover partially defective GPUs while easing up on the clockspeed requirements.
AMD RADEON R9 FURY SERIES
As we mentioned in our R9 Fury X review, we have known since the initial R9 Fury series launch that the R9 Fury utilizes a cut-down Fiji GPU, and we can now reveal just how it has been cut down. Starting things off, let’s take a look at the specifications of the R9 Fury. As a result the R9 Fury at times ends up being a very different take on Fiji, for all of the benefits and drawbacks that comes with. Meanwhile in terms of construction, unlike the R9 Fury X, which is only available in its reference closed loop liquid cooling design, the R9 Fury is available as semi-custom and fully-custom cards from AMD’s board partners, built using traditional air coolers, making this the first air cooled Fiji card. From a performance standpoint it is a lower performing card, featuring a cut-down Fiji GPU, but at the same time it is $100 cheaper than the R9 Fury X. While R9 Fury X remains the fastest Fiji card – and by virtue of being introduced first, the groundbreaking card – the impending launch of the R9 Fury brings with it a whole slew of changes that make it an interesting card in its own right, and a very different take on a Fiji product altogether.
Today we will be taking a look at the first of those remaining cards, the R9 Fury, which launches next week. The first of these remaining cards to launch would be the R9 Fury, the obligatory lower-tier sibling to AMD’s flagship R9 Fury X. These include the R9 Fury, the R9 Nano, and a yet-to-be-named dual-GPU Fiji card. Meanwhile alongside the announcement of the R9 Fury X, AMD announced that there would be three other Fiji-based cards. Overall AMD put together a very impressive card, however at $649 it fell just short of the GeForce GTX 980 Ti AMD needed it to beat. Meanwhile Fiji also marked the introduction of High Bandwidth Memory (HBM) in to consumer products, giving the R9 Fury X a significant leg up in memory bandwidth. Based on the company’s new Fiji GPU, the R9 Fury X brought with it significant performance improvements to AMD’s lineup, with AMD’s massive Fiji greatly increasing the card’s shading resources. A bit over two weeks ago AMD launched their new flagship video card, the Radeon R9 Fury X.
