RTX 4070 vs RX 6800 XT vs RTX 3080 Comparison & Benchmarks

The Nvidia GeForce RTX 40 series graphics card family has expanded further with the launch of the GeForce RTX 4070. The card sits below the GeForce RTX 4070 Ti in the series and is a cut-down version of the RTX 4070 Ti. RTX 4070 is a powerful mid-range graphics card that is targeted for 1440p gaming at maximum settings. However, the card is powerful enough to run the latest AAA games on high settings at 4k resolution while delivering 60+ FPS. The main competitors of RTX 4070 are the Radeon RX 6800 XT from AMD and RTX 3080, an older high-end graphics card from Nvidia built on the Ampere architecture. The gaming performance of these cards is very close to each other but some key differences set them apart. So, if you want to find out how the RTX 4070 stacks against the RX 6800 XT and RTX 3080 then below is a comparison of these cards on important parameters.

Note: The below comparison is made using the original RTX 3080 card that comes with 10 GB VRAM. RTX 3080 also comes with 12GB VRAM and slightly more CUDA Cores. The 12GB RTX 3080 version is only slightly faster than the 10 GB RTX 3080.

RTX 4070 vs RX 6800 XT vs RTX 3080 Comparison

Below is a comprehensive comparison between RTX 4070, RX 6800 XT, and RTX 3080 graphics cards based on their specifications, performance, pricing, power consumption, and features.

GPU Architecture

RTX 4070 is powered by the latest Ada Lovelace GPU architecture and is built on the TSMC 4nm manufacturing process. The card uses a cut-down version of AD104 GPU with some shading units or cores disabled. It comes with 5888 CUDA Cores, 46 RT Cores (3rd Gen.), and 184 Tensor Cores (4th Gen.). On the other hand, RTX 3080 is built on the relatively older Ampere architecture on an 8nm manufacturing process. The card uses 8704 CUDA Cores, 68 RT Cores (2nd Gen.), and 272 Tensor Cores (3rd Gen.). The performance of higher generation RT Cores and Tensor Cores is better than older generation RT Cores and Tensor Cores.

AMD Radeon RX 6800 XT is built on the RDNA 2 architecture on a 7nm fabrication process. The card uses Navi 21 GPU and comes with 4608 Stream Processors, 72 Ray Accelerators, or RT Cores and there are no Tensor Cores on this card.

Features

All three graphics cards come with the latest technologies and support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan and support variable refresh rate technologies (G-Sync/FreeSync) to reduce stuttering in games for a smoother gaming experience, PCIe 4.0, Real-Time Ray Tracing, HDMI 2.1, AV1 decode. When it comes to image upscaling technology to increase performance/FPS in games, RTX 4070 and RTX 3080 support DLSS (Deep Learning Super Sampling). RTX 4070 supports the latest version of DLSS which is DLSS 3 while RTX 3080 supports DLSS 2. On the other hand, Radeon RX 6800 XT supports AMD FidelityFX Super Resolution (FSR) image upscaling technology for games.

Final Thoughts

Well, RTX 4070 is a very good card especially if you play games on 1440p resolution with all graphics settings turned to maximum. The card is also very energy efficient and consumes significantly less power compared to its competitors. Also, it does come with all the latest features and technologies that help to make your gaming experience better and smoother. However, the pricing could have been made a little lower to make a stronger impact on mainstream users who do not the budget for top-end or flagship graphics cards. If you don’t care about Ray Tracing and power efficiency then you can get the RX 6800 XT at a cheaper price and it also comes with extra 4GB memory over RTX 4070 that may come in handy in upcoming AAA titles. Talking about RTX 3080, I think there is no sense in getting it over the competitors unless you find an amazing deal on it.
