Key takeaways
- 1080p: the 4070 Ti usually has its biggest raster lead here, partly thanks to its large L2 cache.
- 1440p: the main battleground, with the 4070 Ti ahead by a single-digit to mid-teens margin in most suites.
- 4K: the gap narrows, and some tests show the 6800 XT level or ahead, helped by its 16 GB and 128 MB Infinity Cache.
Pick the RTX 4070 Ti if you want the faster all-round card: it leads the RX 6800 XT modestly in raster games, by a wide margin in ray tracing, and adds DLSS 3 Frame Generation and DLSS 4’s improved upscaling while using less power. Pick the RX 6800 XT if you are buying used on a tighter budget, mostly play without ray tracing, and want 16 GB of VRAM for texture-heavy games or 4K, where it holds up better than its age suggests.
The two cards sit a generation apart. The RX 6800 XT launched in October 2020 at $649 on AMD’s RDNA 2 architecture. The RTX 4070 Ti arrived in January 2023 at $799 on NVIDIA’s Ada Lovelace architecture. Both are now previous-generation or older parts, so most buyers will be comparing used or remaining-stock prices against current cards such as the RTX 5070 and RX 9070.
Spec Breakdown

|---|---|---|
| Architecture | RDNA 2.0 | Ada Lovelace |
| Release date | 28 October 2020 | 3 January 2023 |
| Launch MSRP | $649 | $799 |

| Process | 7 nm | 4 nm |
| TDP | 300 W | 285 W |
| Memory | 16 GB GDDR6 | 12 GB GDDR6X |
| Memory bus | 256-bit | 192-bit |
| Bandwidth | 512.0 GB/s | 504.2 GB/s |
| Cache | 4 MB L2 + 128 MB Infinity Cache | 48 MB L2 |
| Interface | PCIe 4.0 x16 | PCIe 4.0 x16 |
| Power connectors | 2x 8-pin | 1x 16-pin |

Memory bandwidth is almost identical (512 vs 504 GB/s), and both cards rely on large on-chip caches to compensate for relatively narrow buses. The clear differentiators are capacity (16 GB vs 12 GB) in AMD’s favor and architecture generation in NVIDIA’s favor.
Rasterized Games
The raster gap is smaller than many expect. Benchmark sources disagree on its size: Tech4Gamers measured the RTX 4070 Ti about 5.5% ahead on average, aggregator Technical.city has the two roughly level at 1440p with the 6800 XT ahead at 4K, while review suites weighted toward newer, more demanding games tend to show a larger lead for the 4070 Ti. A reasonable summary is that the RTX 4070 Ti is roughly 5-20% faster at 1440p depending on game selection, with newer Unreal Engine 5 titles tending to favor the NVIDIA card more than older games.
Resolution matters:
- 1080p: the 4070 Ti usually has its biggest raster lead here, partly thanks to its large L2 cache.
- 1440p: the main battleground, with the 4070 Ti ahead by a single-digit to mid-teens margin in most suites.
- 4K: the gap narrows, and some tests show the 6800 XT level or ahead, helped by its 16 GB and 128 MB Infinity Cache.
Both cards run demanding AAA games at 1440p high/ultra settings, typically in the 60-110 FPS range without upscaling, though results swing with settings, CPU and patch.
Ray Tracing and DLSS vs FSR
Ray tracing is where the RTX 4070 Ti pulls well clear. Ada’s third-generation RT cores are dramatically stronger than RDNA 2’s first-generation ray accelerators, and in RT-heavy games such as Cyberpunk 2077, Alan Wake 2 and Black Myth: Wukong, reviewers routinely show leads that dwarf the raster gap. In path-traced modes, the RX 6800 XT is generally not a practical option.
Upscaling and frame generation:
- RTX 4070 Ti: DLSS Super Resolution with the DLSS 4 transformer model, and DLSS Frame Generation (one generated frame per rendered frame). Multi Frame Generation is reserved for RTX 50 cards.
- RX 6800 XT: FSR 3.1 upscaling and frame generation, AMD Fluid Motion Frames in the driver, and XeSS. FSR 4’s ML upscaler officially requires RDNA 4.
DLSS image quality is generally better than FSR 3.1, especially at lower internal resolutions, so the 4070 Ti can run more aggressive upscaling modes without visible shimmer.
Is 12 GB a Problem?
The 4070 Ti’s 12 GB is its weak spot, and it gets tested more every year:
- 1080p and 1440p: 12 GB handles nearly all games at high settings; a few titles with max textures plus ray tracing and frame generation push past it.
- 4K: 12 GB is tight in the heaviest games, and texture settings may need to drop.
- Mods and AI: the 6800 XT’s 16 GB gives more room, though NVIDIA’s CUDA ecosystem is better supported for AI tools.
Power, PSU and Physical Size
| Card | GPU | CPU | Headroom | Total | Recommended PSU |
|---|---|---|---|---|---|
| RX 6800 XT | 300 W | 125 W | 150 W | 575 W | Quality 650-750 W, 2x 8-pin |
| RTX 4070 Ti | 285 W | 125 W | 150 W | 560 W | Quality 650-750 W, 16-pin or adapter |
Rated power is close, but in practice reviewers found the RTX 4070 Ti’s gaming power draw often sits well below its 285 W rating, while RDNA 2 cards are known for brief transient spikes. The 4070 Ti uses a 16-pin connector; newer ATX 3.x PSUs have a native cable, and older ones use the bundled adapter, which must be fully seated. The 6800 XT uses two standard 8-pin cables.
On size, the RTX 4070 Ti’s listed 285 mm length is a bit longer than the 6800 XT’s 267 mm, and many partner 4070 Ti models are 3-slot coolers well beyond 300 mm, so check case clearance carefully.
Value: Launch Price and Used Market
At launch MSRPs, with the 6800 XT as 100 and the 4070 Ti as roughly 112 (middle of the 1440p raster range):
- RX 6800 XT: $649 / 100 = about $6.49 per performance point.
- RTX 4070 Ti: $799 / 112 = about $7.13 per performance point.
In raster-only terms the 6800 XT was slightly better value at launch, but the 4070 Ti’s ray tracing and DLSS add value that this math does not capture. Today, used RX 6800 XT cards usually sell around $280-$350, while used RTX 4070 Ti cards usually go for around $450-$550. That gap is large enough that the 6800 XT is the budget raster pick, while the 4070 Ti competes with a new RTX 5070, which offers similar performance plus Multi Frame Generation and a warranty.

| Play at 4K with high textures | RX 6800 XT for VRAM, 4070 Ti with DLSS |
| Stream or use NVIDIA-specific tools | RTX 4070 Ti |
| Game on Linux | RX 6800 XT |
| Can stretch to new cards | Compare against RTX 5070 or RX 9070 first |
Software, Streaming and Longevity
Beyond frame rates, the two cards differ in their software ecosystems. The RTX 4070 Ti includes NVIDIA’s NVENC encoder with AV1 support, which gives streamers and video creators better quality at the same bitrate. It also benefits from CUDA support in Blender, DaVinci Resolve and many AI tools, plus NVIDIA Broadcast for microphone noise removal. The RX 6800 XT’s encoder handles H.264 and HEVC but lacks AV1 encoding, which arrived on Radeon with RDNA 3.
On the other hand, AMD’s Adrenalin software combines tuning, recording, Radeon Anti-Lag and Fluid Motion Frames in a single app, and AMD’s open-source Linux drivers are a real advantage for Linux gaming setups.
Longevity cuts both ways. The 4070 Ti is newer and keeps receiving DLSS model improvements, while the 6800 XT’s 16 GB protects it against rising texture budgets. If you keep cards for four or more years and play with high textures, memory capacity may matter more; if you play the newest ray-traced releases, the 4070 Ti’s features will age better.
Frequently Asked Questions
Is the RTX 4070 Ti much faster than the RX 6800 XT?
In raster games, it is roughly 5-20% faster at 1440p depending on the review and game selection. With ray tracing enabled, the gap becomes much larger in the 4070 Ti’s favor.
Does the RTX 4070 Ti support DLSS 4?
It supports DLSS 4’s transformer-based upscaling and DLSS Frame Generation. Multi Frame Generation, which inserts several frames per rendered frame, is limited to RTX 50 series cards.
Is the RX 6800 XT still good in 2026?
Yes, for raster gaming at 1080p and 1440p it remains capable, and 16 GB of VRAM keeps it comfortable with high textures. Its weaknesses are ray tracing performance and lack of FSR 4 support.
Will 12 GB on the RTX 4070 Ti hold up?
At 1440p it handles nearly all current games at high settings. Some new titles with maximum textures plus ray tracing exceed 12 GB, so a texture setting drop may be needed. At 4K the limit shows up more often.
What PSU does each card need?
A quality 650-750 W unit suits either card with a mainstream CPU. The RX 6800 XT needs two 8-pin cables; the RTX 4070 Ti needs a 16-pin cable or the included adapter.
