NVIDIA GeForce RTX 4070 Ti vs NVIDIA GeForce RTX 4080 Comparison

Head-to-Head Benchmarks

The data is unambiguous: the NVIDIA GeForce RTX 4080 wins every single recorded benchmark against the RTX 4070 Ti, with a 10-0 sweep in the head-to-head comparison. The average benchmark score for the RTX 4080 is 54,247, while the RTX 4070 Ti sits at 44,795, a gap of roughly 21% in overall performance. The largest margin comes in the 3DMark Steel Nomad DX12 test, where the RTX 4080 scores 6,567 against the RTX 4070 Ti's 5,024, a 30.7% advantage. This is not a close contest; the RTX 4080 is decisively faster across every workload measured.

The compute-oriented benchmarks reinforce this dominance. In Geekbench OpenCL, the RTX 4080 posts 214,739 versus 176,953, a 21.4% lead. The Vulkan test shows a similar story: 263,779 against 213,808, a 23.4% advantage. For GPU compute workloads, the PassMark GPU Compute score is 20,671 for the RTX 4080 and 18,396 for the RTX 4070 Ti, a 12.4% lead. These results indicate that the RTX 4080's extra silicon translates directly into higher throughput for both graphics and general-purpose compute tasks.

DirectX legacy tests show smaller but still consistent gaps. In PassMark DirectX 10, the RTX 4080 scores 204 versus 187, a 9.1% lead. DirectX 11 shows 314 against 288, a 9% difference. DirectX 12 yields 132 versus 116, a 13.8% advantage. Even DirectX 9, the oldest API tested, shows the RTX 4080 ahead at 370 versus 352, a 5.1% margin. The 2D performance gap is the narrowest of all: 1,239 versus 1,200, just 3.3%, which makes sense given that 2D workloads are rarely GPU-bound. The PassMark G3D score, a broad gaming-oriented metric, is 34,457 for the RTX 4080 and 31,624 for the RTX 4070 Ti, a 9% lead.

Where Each One Wins

Given the 10-0 sweep, the RTX 4080 wins every category in this comparison. In gaming workloads, represented by the 3DMark Steel Nomad DX12 and PassMark G3D tests, the RTX 4080 leads by 30.7% and 9%, respectively. If you are targeting high refresh rates at 4K or pushing ray tracing settings, the RTX 4080's compute advantage will be the deciding factor. For creative applications that leverage GPGPU compute, the PassMark GPU Compute score of 20,671 versus 18,396 (12.4% lead) and the Geekbench OpenCL score (21.4% lead) show the RTX 4080 handles rendering, simulation, and AI-assisted workflows with more headroom.

The RTX 4070 Ti, while losing every benchmark, is still a capable GPU on its own. Its average benchmark score of 44,795 places it in the 84th percentile of all GPUs, so it is not a slow card by any stretch. The RTX 4080, however, sits in the 86th percentile, and the gap between them is consistent across all tested APIs. In practical terms, the RTX 4070 Ti would be the choice if you need a dual-slot card with a shorter length (285 mm versus 310 mm) and a lower power draw (285 W versus 320 W), which matters for smaller cases or weaker power supplies. But in pure performance terms, there is no workload in the database where the RTX 4070 Ti comes out ahead.

Architecture Differences

Both cards use the Ada Lovelace architecture, built on TSMC's 5 nm process node. The RTX 4080 is based on the AD103 chip with 45,900 million transistors on a 379 mm² die, giving a transistor density of 121.1 million per square millimeter. The RTX 4070 Ti uses the AD104 chip with 35,800 million transistors on a 294 mm² die, with a slightly higher density of 121.8 million per square millimeter. The die size difference is substantial: the RTX 4080's chip is about 29% larger, which explains its higher transistor count and performance headroom.

The memory subsystem differs considerably. The RTX 4080 has 16 GB of GDDR6X on a 256-bit bus, delivering 716.8 GB/s of bandwidth. The RTX 4070 Ti has 12 GB of GDDR6X on a 192-bit bus, with 504.2 GB/s of bandwidth. That is a 42% bandwidth advantage for the RTX 4080, which directly impacts high-resolution texture streaming and memory-heavy workloads. The RTX 4080 also runs its memory at 1,400 MHz (22.4 Gbps effective) versus 1,313 MHz (21 Gbps effective) on the RTX 4070 Ti.

The compute resources scale accordingly. The RTX 4080 has 9,728 shading units, 304 texture mapping units, and 112 ROPs, while the RTX 4070 Ti has 7,680 shading units, 240 TMUs, and 80 ROPs. Ray tracing cores tally 76 on the RTX 4080 versus 60 on the RTX 4070 Ti, and tensor cores count 304 versus 240. The pixel rate is 280.6 GPixel/s for the RTX 4080 and 208.8 GPixel/s for the RTX 4070 Ti; texture rate is 761.5 GTexel/s versus 626.4 GTexel/s. FP32 compute is 48.74 TFLOPS versus 40.09 TFLOPS, a 21.6% difference that matches the average benchmark gap.

Clock speeds are the one area where the RTX 4070 Ti leads. Its base clock is 2,310 MHz and boost clock is 2,610 MHz, compared to 2,205 MHz base and 2,505 MHz boost on the RTX 4080. The RTX 4070 Ti runs about 4-5% faster in raw clock speed, but the RTX 4080's larger chip and wider memory bus more than compensate. Both cards support PCIe 4.0 x16, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs are identical: 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The Verdict

The benchmark data makes the choice straightforward for anyone prioritizing raw performance: the RTX 4080 wins every single recorded test. Its 30.7% lead in 3DMark Steel Nomad and 21-23% leads in Geekbench OpenCL and Vulkan show a GPU that is meaningfully faster in both gaming and compute scenarios. The larger die (379 mm² versus 294 mm²), more transistors (45,900 million versus 35,800 million), and wider memory bus (256-bit versus 192-bit) all contribute to this consistent advantage. The RTX 4080 also offers 16 GB of memory versus 12 GB, which provides more headroom for future titles and larger textures.

The RTX 4070 Ti is not a weak card, and its 84th percentile standing among all GPUs confirms that. It runs at higher clocks (2,610 MHz boost versus 2,505 MHz), draws less power (285 W versus 320 W), and fits in a smaller dual-slot package that is 25 mm shorter. For builders with limited case space or a 600 W power supply, the RTX 4070 Ti is the more practical fit. But the data shows no workload where it catches up to the RTX 4080. If you need the fastest option in this comparison and can accommodate the larger physical footprint, the RTX 4080 is the clear pick. If compact dimensions and lower power draw matter more than peak performance, the RTX 4070 Ti remains a credible alternative, but it will trail in every measurable benchmark.
