Savvy buyers are buying older cards, often used cards for crossfire rigs that beat their latest offerings at a fraction of the cost. Visual representation of the products may not be perfectly accurate.
Now look at Vega 64 in Crossfire and the vega rig is significantly better at all resolutions. I am getting similar framerates (to ideal CrossFire framerates with my old graphics cards and a 27" 1440p non FreeSync monitor), without the hassle and side effects of CrossFire.

Overclocking Vega 64 in the classic way, where you set a clock speed is not the easiest way to overclock.

Vega core clocks are now more to do with the voltage you provide/allow it to use.

Now, that’s just the cost. If there were enough Vega GPUs to go around, Gigabyte's Radeon RX Vega 64 OC 8G would probably be great for high-end performance at a reasonable price. Crossfire Vega 64 with Vega 56.

Given the support for CrossFire is limited and in some case terrible even for those games supported to me, there is no reason to purchase dual cards to place in Crossfire especially when you buy a solo GTX 1080 for about $40 less than 2 RX 580 cards and get the same or better performance and be assured … Modelling applications in particular benefit from this and this allows large 3D models to be rendered in near real-time. Also ensure P6 and … For Vega 64 CrossFire, you will be spending roughly $1,000. Setting higher P7 state would result in instability. The AMD Radeon RX Vega 64 graphics cards offer geometry calculations with 11 polygons (when using 4 Geometry Units) per clock and therefore twice as many as the Radeon R9 Fury X with its 4 polygons per clock with 4 Geometry Units. Amd have twigged! All images and descriptions are for illustrative purposes only. Each NCU houses 64 steam processors, of which the Vega 64 has 4096 compared to 3584 in the Vega 56. The architecture also employs 8GB of second generation high-bandwidth memory (HBM2). The AMD Radeon RX Vega 64 is built on 14 nm silicon and contains next-generation compute units (nCUs). AMD RX VEGA 64 is among the top-end graphics cards from the AMD team and recently the release of the RX 5700-series graphics cards has put an end to the extreme prices of this graphics card. I bought this Asus ROG Strix OC Gaming RX Vega 64 to replace my aging and failing CrossFired pair of Sapphire Tri-X OC R9 290x's to power a new 32" FreeSync 1440p monitor for gaming, and I am not disappointed.

At launch (two years ago) AMD described this as the most significant leap in their GPU architecture … Vega 64 is slightly slower than the Nvidia GTX 1080 Ti in the DX-11 titles while the performance in DX-12 is quite identical. System Name: Home Brewed: Processor: i9-7900X and i7-8700K: Motherboard: ASUS ROG Rampage VI Extreme & ASUS Prime Z … Thread starter RealNeil; Start date Oct 3, 2018; Tags GPU Overclocking Graphics Cards Radeon; RealNeil Supporter. Product specification, functions and appearance may vary by models and differ from country to country .
All my testing was done by setting the P6 State to 1632 and P7 to 1682, then leaving them there and undervolting to see the results.
