AMD Radeon RX 7700 XT vs NVIDIA GeForce RTX 3070 Ti Mobile Comparison

# NVIDIA GeForce RTX 3070 Ti Mobile vs AMD Radeon RX 7700 XT

These two GPUs occupy different corners of the market: the RTX 3070 Ti Mobile is an end-of-life laptop part from the Ampere generation, while the RX 7700 XT is an active desktop card built on RDNA 3.0. The benchmark data shows a clear overall winner in raw performance, but the RTX 3070 Ti Mobile holds specific advantages that matter for certain workloads. The AMD card wins 8 of 10 head-to-head tests, yet the NVIDIA part dominates one major API benchmark by a wide margin.

Where Each One Wins

The AMD Radeon RX 7700 XT wins the vast majority of direct comparisons, and it wins them by substantial margins. In compute-oriented workloads, the gap is enormous: the RX 7700 XT scores 12,912 in Passmark GPU Compute, a 41.9% advantage over the RTX 3070 Ti Mobile’s 7,504. That is the largest single-test delta in the entire comparison. The story repeats in DirectX 11 and DirectX 9 legacy tests, where the AMD card leads by 34.1% (232 vs 153) and 33.3% (294 vs 196) respectively. Even in modern DirectX 12, the RX 7700 XT takes the win with 79 vs 73, though the margin is just 7.6%.

The NVIDIA GeForce RTX 3070 Ti Mobile wins only two tests, but one of them is a headline result. In Geekbench Vulkan, the mobile NVIDIA part scores 100,027 against the RX 7700 XT’s 46,443 — a 115.4% lead that more than doubles the AMD card’s score. This suggests the RTX 3070 Ti Mobile has exceptionally strong Vulkan driver optimization or architecture-level advantages in that API. The second NVIDIA win is Passmark DirectX 10, where it edges ahead 124 vs 119, a modest 4.2% margin.

In 3DMark Steel Nomad DX12, the RX 7700 XT posts 3,316 against 2,572 for the RTX 3070 Ti Mobile, a 22.4% lead. The AMD card also wins Passmark G3D by 21.4% (22,547 vs 17,727) and OpenCL by 23.4% (138,383 vs 106,022). The 2D workload favors AMD as well, with 1,161 vs 783, a 32.6% gap.

The Verdict

The data points to a simple conclusion: the AMD Radeon RX 7700 XT is the faster GPU in nearly every measurable scenario. Eight wins out of ten head-to-head tests, with margins ranging from 7.6% to 41.9%, makes this a decisive overall victory. The average benchmark score reinforces this — the RX 7700 XT averages 22,549 across all tests, while the RTX 3070 Ti Mobile averages 23,518. Wait, that math needs a closer look. The average score for the NVIDIA part is actually higher (23,518 vs 22,549), which seems to contradict the head-to-head results. This happens because the average includes all benchmark data, not just the paired tests, and the RTX 3070 Ti Mobile’s massive Vulkan score pulls its average up.

So who should pick which? If you are building a desktop system and want the strongest all-around performer, the RX 7700 XT is the clear choice from the data. It wins in compute, DirectX 11, DirectX 12, 3DMark, and OpenCL. The RTX 3070 Ti Mobile is a mobile part, so its relevance is limited to laptops, but if you are comparing it as a potential eGPU or in a system where Vulkan performance is critical, its 115.4% Vulkan advantage is a decisive factor. The RTX 3070 Ti Mobile also holds the edge in DirectX 10, which may matter for older games or specific professional applications.

The RX 7700 XT sits at the 67th percentile among all GPUs, while the RTX 3070 Ti Mobile sits at the 69th percentile — essentially neck-and-neck in overall standing. The nearest rivals tell a similar story: the RTX 3070 Ti Mobile trades blows with the RTX 3080 Mobile (0.5% behind) and the GTX TITAN Z (0.9% ahead), while the RX 7700 XT is 0.5% ahead of the RTX 5060 Mobile and 0.8% behind the RTX 4060 Mobile. These are tight clusters, but the head-to-head data breaks the tie firmly in AMD’s favor for most workloads.

Head-to-Head Benchmarks

The biggest single win for either card is the Geekbench Vulkan test, where the RTX 3070 Ti Mobile scores 100,027 against the RX 7700 XT’s 46,443. That is a 115.4% advantage, meaning the NVIDIA card more than doubles the AMD card’s score. This is the kind of result that can completely change a purchasing decision if your primary applications use Vulkan.

On the AMD side, the Passmark GPU Compute test delivers the largest margin: 12,912 vs 7,504, a 41.9% lead. This is a strong indicator for compute-heavy workloads like rendering, machine learning inference, or scientific simulations. The DirectX 11 test shows a 34.1% gap (232 vs 153), and DirectX 9 shows a 33.3% gap (294 vs 196), both favoring AMD. The 2D test also goes to AMD by 32.6% (1,161 vs 783).

The 3DMark Steel Nomad DX12 test is a modern gaming workload, and the RX 7700 XT wins 3,316 vs 2,572, a 22.4% lead. OpenCL follows a similar pattern with a 23.4% margin (138,383 vs 106,022). Passmark G3D, a general 3D graphics benchmark, goes to AMD by 21.4% (22,547 vs 17,727). The smallest AMD win is DirectX 12 at 7.6% (79 vs 73), and the smallest NVIDIA win is DirectX 10 at 4.2% (124 vs 119).

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The RTX 3070 Ti Mobile uses NVIDIA’s Ampere architecture, built on an 8 nm process at Samsung, with 17,400 million transistors on a 392 mm² die. The RX 7700 XT uses AMD’s RDNA 3.0 architecture, built on a 5 nm process at TSMC, packing 28,100 million transistors into a smaller 346 mm² die. The transistor density tells the story: the AMD chip achieves 81.2 million transistors per mm², nearly double the NVIDIA part’s 44.4 million per mm².

The RTX 3070 Ti Mobile is built around the GA104 chip, while the RX 7700 XT uses the Navi 32 chip (codename "Wheat Nas"). The NVIDIA card features 5,888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores. The AMD card has fewer shading units at 3,456, but more TMUs at 216, the same 96 ROPs, and more RT cores at 54. The NVIDIA part has tensor cores for AI workloads, while the AMD card has no tensor core equivalent listed.

Clock speeds differ dramatically. The RTX 3070 Ti Mobile runs at a 915 MHz base and 1,410 MHz boost, while the RX 7700 XT runs at 1,435 MHz base, 2,544 MHz boost, and a 2,171 MHz game clock. The AMD card’s boost clock is nearly double the NVIDIA card’s base clock. This clock advantage translates into raw throughput: the RX 7700 XT delivers 35.17 TFLOPS FP32 vs 16.60 TFLOPS for the RTX 3070 Ti Mobile, a 111.9% difference despite the AMD card having fewer shading units.

Specification Differences

The memory configurations diverge in capacity but converge in bandwidth. The RTX 3070 Ti Mobile has 8 GB of GDDR6 on a 256-bit bus, delivering 448.0 GB/s. The RX 7700 XT has 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. The NVIDIA card has slightly higher bandwidth despite less capacity and a wider bus, but the AMD card offers 50% more memory capacity.

Power requirements are dramatically different. The RTX 3070 Ti Mobile has a TDP of 115 W and uses no external power connectors, reflecting its mobile design. The RX 7700 XT has a TDP of 245 W, requires two 8-pin power connectors, and needs a 550 W suggested PSU. The AMD card also has a dual-slot form factor, physical dimensions of 267 mm by 135 mm by 50 mm, and display outputs including 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C. The NVIDIA card’s display outputs are listed as "Portable Device Dependent."

The production status differs as well: the RTX 3070 Ti Mobile is end-of-life, released in January 2022, while the RX 7700 XT is active, released in September 2023. The AMD card has a launch MSRP of 449 USD. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both use a PCIe 4.0 x16 bus interface. The RTX 3070 Ti Mobile’s memory runs at 14 Gbps effective, while the RX 7700 XT’s memory runs at 18 Gbps effective, though the NVIDIA card’s wider bus compensates for the lower speed.
