AMD Radeon Fury X beats Titan X in OpenCL
So the funny thing about people is that once they have cool hardware, they test stuff and sometimes forget that the results of a benchmark can be inserted into an online database, which is publicly available. AMD Radeon Fury (Fiji) just popped up in an OpenCL benchmark, confirming a number of things.
The leak shows that the HBM based Fiji XT aka Radeon Fury X slaps around the NVIDIA GeForce GTX Titan X, with a good margin as well. It is OpenCL though, compute stuff. And then again, the R9 280X is not be that far behind the Titan X either - so here you immediately see why we don't do OpenCL benchmarks in our benchmarks as they say very little.
The card shown as "AMD Radeon Graphics Processor" would be Fiji / Fury X. The Fury X drops the ball to the Titan X in a 'face detection' test on CompuBench, yet beats the Titan X once again in the 'TV-L1 Optical Flow' test. AMD Radeon Fury X scores 102FPS on the Manhattan benchmark found in GFXBench where Titan X it doing 137FPS.
Now there is something else quite intersting you can extrapolate from these results, the GPGPU Info app registers how many compute units (CUs) a GPU has as well as the GPU codename hence we can verify this was the real thing.
- Name: Fiji
- max_clock_frequency 1000
- max_compute_units 64
GFXBench shows a Compute Unit count of 64 multiply that with GCN architecture, thus per compute unit you will see 64 stream processors, and we now know the number of shader processors for Fiji, 64 shader processors x 64 CUs = 4096 shader processors.
It also is listing the maximum clock frequency at 1 GHz. If we chart things up it would look something like this:
AMD Radeon Fiji | AMD Radeon R9 390 | |
Fabrication Process | 28nm | 28nm |
GPU | Fiji | Hawaii renamed to Grenada |
Streaming Processors | 4096 | 2816 |
Graphics memory | 4 GB HBM | 8 GB GDDR5 |
Memory Clock | up-to 500 MHz per stack (x4) | 5.0 GHz |
Core Clock | > 1.00 GHz | > 1.00 GHz |
Memory Bandwidth | >640 GB/s | 320 GB/s |
Power Connectors | 1 x 6-pin - 1 x 8-pin | 1 x 6-pin - 1 x 8-pin |
Form Factor | Full Height, Dual slot | Full Height, Dual slot |
Freesync | Yes | Yes |
DirectX 12 Support | Yes | Yes |
Can I just say one thing ? OpenCL Compubench means very little ... real games with real DX11/DX12 software is where the money shot is to be found of course. AMD Radeon Fury X and Radeon R9 390X will be unveiled next week at E3 2015.

AMD Radeon R9 390X To Skip Computex - Launches at E3 - 05/13/2015 11:51 AM
With AMD sponsoring a PC Gaming event at E3, this kind of was to be expected. It seems now that the Radeon R9 390X will not show up next month in Taiwan's Computex. But rather will be revealed at E3...

The article also says this.
Its all speculation at this point though

according to wcc the Fiji have very slight better score that titanx, means nothing atm. but i do believe 980ti and fiji are toe to toe, with fiji is better for 4K but still not enough.

Not sure if this has been here before but just forwarding it.
Not believing anything until next week.
The most reasonable conclusion is a slight performance edge for Fury X, until the 4GB of RAM is allocated, in which case the Titan will rape it, so the Fury X will be sold at a lower MSRP then the Titan
I'm more interested in the Fury, since its competition has 6GB of RAM, so it's only -2GB to get a Fury instead of a 980ti. I'm sure dat 4096 bit memory bus will result in better performance (10% or so...I'm sure the GPU core clock bottlenecks it) then the 512 bit 980ti, and if it's a lower MSRP too...
