Specs Comparison: Nvidia GTX 1080 Ti Founder’s Edition v/s XFX Radeon RX Vega:

From the above side-by-side comparison, you should have a rough idea about how these graphics processors differ from each other. Now, let us compare to GPUs based on them side by side. As we mentioned at the beginning of the article, we have picked Nvidia GTX 1080 Ti Founder Edition (based on GTX 1080 Ti) and XFX Radeon RX Vega 64 (based on RX Vega 64) for this comparison. It will make you understand the main differences in the two models. Here we begin:

GENERAL

Specifications Nvidia GeForce GTX 1080 Ti Founder’s Edition

XFX Radeon RX Vega 64 Graphics Card

Interface Type PCI Express 3.0 PCI Express 3.0
Max Monitors Supported Not Specified 6
Interfaces 3 x DisplayPort

3 x DisplayPort
Graphics Engine NVIDIA GeForce GTX 1080 Ti AMD Radeon RX VEGA 64
Bus Type PCI Express 3.0 PCI Express 3.0
Boost Clock 1582 MHz 1546 MHz
API Supported DirectX 12, OpenGL 4.5, Vulkan, DirectX 12.1 OpenCL, DirectX 12, OpenGL 4.5, Vulkan
CUDA Cores / Stream Processors 3584 4096
Manufacturer Nvidia XFX Inc

As we can see, the only difference here is the boosted clock, and Cuda core and stream processors count. However, the difference in the boosted clock is pretty novice. Nvidia offers 36 MHz more on boosted clock compared to XFX Graphics card. However, XFX offers 512 more stream processors compared to Cuda cores count in Nvidia GeForce. Moreover, Nvidia offers the new DirectX 12.1 API support, which is missing on the XFX. Do note that the GPU supports 12.3 features, however, some features not supported that drives them not to be DTX 12.1 compliant. Rest of the things are pretty much the same.

MEMORY

XFX Radeon RX Vega 64 Graphics Card

Size 11 GB 8 GB
Bus Width 352-bit 2048-bit
Bandwidth 484 GB/s 483 GB/s
Technology GDDR5X SDRAM HBM2

There is a huge difference of almost 3 GB in the total memory size these graphics card offer, as Nvidia is offering 11 GB, while XFX Radeon does only 8 GB. Moreover, the bus width of XFX is about 1732 bit wider compared to Nvidia GeForce. The difference in memory bandwidth is a novice. XFS Radeon uses HBM2 technology while Nvidia GeForce GTX 1080 Ti uses GDDR5X SDRAM. Note than HBM2 is better since it can be compressed at higher levels and it’s a bit faster too. However, we are not sure if VRAM speed matters while gaming.

As the table implies, most of the specs here are similar. However, XFX has a wider range of video adapter features including AMD Liquid VR technology, True Audio Technology, VR Ready Premium, etc. Moreover, It lacks support for DirectX 12.1 API. Here you might easily not that Nvidia supports wider external resolution than XFX Graphics card.

SYSTEM REQUIREMENTS

XFX Radeon RX Vega 64 Graphics Card

OS FreeBSD (32-bit), Linux, Microsoft Windows 7 / 8 / 8.1 / 10 Windows 10
Required Power Supply 250 750

Nvidia Founder’s addition has confirmed to be working with most of the modern Windows operating systems including Linux and FreeBSD. However, it is still not confirmed if XFX works with Linux. Moreover, there is hugely different in the required power supply as Nvidia requires only 250 Watts while XFX requires 750. It is quite considerable as the performance of XFX is superior over Nvidia.
