The competition in the best value high-end graphics cards segment has become very fierce with the launch of Radeon RX 6800. It is the third card in the AMD Radeon RX 6000 series as it sits below the Radeon RX 6900 XT and RX 6800 XT. The direct competitor of Radeon RX 6800 is the GeForce RTX 3070 which is the third card in the RTX 30 series from Nvidia. RX 6800 and RTX 3070 are high-end cards that offer incredible performance for the price. The cards are powerful for high refresh rate 1440p gaming and are equally good enough for 4K gaming too. So, if you are confused about which card to get for your next or current gaming rig then here, I am going to compare both these cards on various important parameters.

RX 6800 vs RTX 3070 Comparison

Below is the comparison between RX 6800 and RTX 3070 graphics cards based on their specifications, performance, pricing, power consumption, and features.

GPU Architecture

Radeon RX 6800 is built on the RDNA 2 architecture on a 7nm fabrication process and uses the Navi 21XL GPU chip. The card comes with 3840 Stream Processors and has 60 Ray Accelerators or Ray Tracing Cores. Unlike Nvidia, the card does not come with Tensor Cores or equivalent for Artificial Intelligence processing. On the other hand, RTX 3070 is built on the Ampere GPU architecture on the 8nm process. The card uses GA104 chip and comes with 5888 CUDA Cores, 46 Ray Tracing Cores, and 184 Tensor Cores for AI processing.

Ray Tracing Cores 46 60
Tensor Cores 184 NA

Video Memory [VRAM]

When it comes to video memory then RX 6800 is a clear winner. The card comes with 16GB GDDR6 memory which is twice of the RTX 3070. The memory is 256-bit wide and runs at a faster speed of 16Gbps and has an effective bandwidth of 512 GB/s. However, RX 6800 can reach a peak bandwidth of 1664 GB/s (3.25x effective bandwidth) by using the 128 MB Infinity Cache which is an ultra-fast cache memory present on the RX 6800 GPU for accelerating the memory bandwidth for memory-intensive tasks e.g. Ray Tracing enabled in supported game.

Memory Size 8 GB GDDR6 16 GB GDDR6
Memory Interface 256-bit 256-bit
Memory Speed 14 Gbps 16 Gbps
Memory Bandwidth 448 GB/s 512 GB/s
Infinity Cache NA 128 MB

Features

The cards support the latest graphics APIs that include DirectX 12 Ultimate, OpenGL 4.6, and Vulkan and have their own variable refresh rate technologies (G-Sync/FreeSync) to reduce stuttering in games for a smooth gaming experience. Moreover, both of the cards support PCI-Express 4.0, Real Time Ray Tracing, HDMI 2.1, AV1 decode, Microsoft DirectStorage API (to reduce game loading times). There is a lack of multi-GPU support on both the cards which means you cannot use them in SLI or CrossFire configuration. The features that are only present in the RX 6800 XT include a USB Type-C connector and Smart Memory Access (SAM) (with Ryzen 5000 series CPUs and 500 series motherboards) that allow the CPU to access all of the graphics card memory for improved performance in select games. The features that are related to RTX 3070 only are the Nvidia Reflex and DLSS 2.0 (Deep Learning Super Sampling).

Final Thoughts

There is absolutely no doubt that the RX 6800 is an excellent product that offers much more even when compared to the less expensive RTX 3070. RX 6800 comes with 8GB extra VRAM that can prove very helpful in upcoming AAA titles even at 1440p resolution. The performance of the RX 6800 is remarkable and it also comes very close to the RX 6800 XT, its bigger brother. RTX 3070 offers very good performance for the price but I think that the 8GB VRAM on a 500-dollar card in the year 2020 is a bit of a letdown. If I have to pick between the two, then I would be picking RX 6800 for sure.
