AMD Radeon RX 6750 XT vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

The NVIDIA GeForce RTX 5070 Ti Mobile and AMD Radeon RX 6750 XT are effectively tied in overall average benchmark score, with the NVIDIA part leading by a razor-thin 0.3% (35435 vs 35327). However, this near-parity in aggregate hides a decisive split: the RTX 5070 Ti Mobile wins 8 of 9 head-to-head tests, often by substantial margins, while the RX 6750 XT claims only a single legacy DirectX 9 victory. The data indicates the NVIDIA mobile GPU is the stronger modern performer, leveraging its newer architecture and higher bandwidth to dominate compute and DirectX 11/12 workloads, whereas the AMD card retains a narrow edge in an older API scenario.

Where Each One Wins

The use-case split is stark and favors NVIDIA for virtually all contemporary workloads. The RTX 5070 Ti Mobile wins every modern benchmark category, with its largest advantages appearing in compute-heavy and DirectX 11/12 scenarios. For OpenCL compute, the NVIDIA GPU leads by 33.7%, a massive gap that suggests significantly better performance in GPU-accelerated productivity, rendering, and AI-adjacent tasks. Similarly, in DirectX 11 and DirectX 12, the RTX 5070 Ti Mobile is ahead by 31.7% and 27.5% respectively, which directly translates to better performance in the vast majority of current PC games that rely on these APIs. The Vulkan result also favors NVIDIA by 27.4%, reinforcing that the mobile part is the better choice for modern game engines and cross-platform titles.

The AMD Radeon RX 6750 XT’s sole win comes in the Passmark DirectX 9 test, where it scores 263 versus 259, a 1.5% lead. This is a legacy API with limited relevance to modern titles, indicating the AMD card’s advantage is confined to older software or specific emulation scenarios. In every other measured category—including 2D graphics, where NVIDIA leads by a marginal 0.9%—the RTX 5070 Ti Mobile takes the win. The data suggests that for gaming, content creation, or compute workloads built on modern standards, the NVIDIA part is the clear choice. The AMD card’s only path to victory is strictly in backward-compatible, older DirectX 9 titles, a niche that few users will prioritize.

Architecture Differences

The architectural gap between these two GPUs is generational. The RTX 5070 Ti Mobile is built on NVIDIA’s Blackwell 2.0 architecture using a 5 nm process at TSMC, while the RX 6750 XT uses the older RDNA 2.0 architecture on a 7 nm process. This process advantage is reflected in transistor density: the NVIDIA chip packs 118.3 million transistors per mm² versus AMD’s 51.3 million, despite the AMD die being larger at 335 mm² compared to 263 mm². The RTX 5070 Ti Mobile’s GB205 chip contains 31,100 million transistors, nearly double the 17,200 million in the Navi 22, which explains its higher shader count of 5888 versus 2560.

Memory technology also differs significantly. The NVIDIA GPU uses 12 GB of GDDR7 memory with a 192-bit bus, achieving 672.0 GB/s of bandwidth, while the AMD card uses 12 GB of GDDR6 on the same bus width but with only 432.0 GB/s. This 55.6% bandwidth advantage for NVIDIA is a critical factor in its benchmark wins, particularly in compute and high-resolution scenarios. Clock speeds tell a different story: the RX 6750 XT runs at a base of 2150 MHz and boosts to 2600 MHz, far above the RTX 5070 Ti Mobile’s 847 MHz base and 1447 MHz boost. However, the NVIDIA part’s much higher shader count and newer architecture compensate for the lower clocks, as evidenced by its superior FP32 throughput of 17.04 TFLOPS versus 13.31 TFLOPS for AMD. Notably, the AMD GPU offers higher FP16 performance at 26.62 TFLOPS due to a 2:1 ratio, while NVIDIA’s FP16 matches its FP32 at 17.04 TFLOPS.

Head-to-Head Benchmarks

The benchmark results show a consistent pattern of NVIDIA dominance, with the largest margins in compute and modern API tests. The biggest single win for the RTX 5070 Ti Mobile is in Geekbench OpenCL, where it scores 143,870 against 107,621 for the RX 6750 XT, a 33.7% advantage. This result alone suggests the NVIDIA GPU is substantially better suited for OpenCL-based compute tasks, which are common in scientific, engineering, and some rendering workloads. The DirectX 11 test shows a similar story, with NVIDIA at 237 versus 180, a 31.7% lead, indicating that the majority of DirectX 11 games will run noticeably faster on the mobile part.

In DirectX 12, the RTX 5070 Ti Mobile scores 102 versus 80, a 27.5% advantage, which is significant for modern AAA titles that heavily utilize this API. The Vulkan test follows suit with NVIDIA at 139,213 versus 109,310, a 27.4% lead, confirming that the NVIDIA GPU is better optimized for open-standard graphics APIs. The Passmark G3D test, which is a broad gaming-oriented metric, shows NVIDIA at 24,004 versus 20,700, a 16% win. Compute performance in Passmark GPU Compute also favors NVIDIA, with 10,101 versus 9,550, a 5.8% lead. The only AMD victory is in DirectX 9, where the RX 6750 XT scores 263 versus 259, a marginal 1.5% difference that is unlikely to matter for modern users.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 5070 Ti Mobile is the superior GPU for nearly all measured workloads. With 8 wins out of 9 head-to-head tests and a 33.7% lead in OpenCL compute, it is the clear choice for users prioritizing modern gaming performance, compute acceleration, or any workload that leverages DirectX 11, DirectX 12, or Vulkan. The RX 6750 XT’s single victory in DirectX 9 is a legacy holdover that does not compensate for its significant deficits elsewhere. The NVIDIA part also offers substantially higher memory bandwidth (672.0 GB/s vs 432.0 GB/s) and a newer 5 nm process, which explains its efficiency despite a much lower TDP of 60 W versus 250 W for AMD. For any user building a system around current software, the RTX 5070 Ti Mobile is the data-backed recommendation.

The AMD Radeon RX 6750 XT is not without merit, but its strengths are confined to a narrow niche. Its higher clock speeds (2600 MHz boost vs 1447 MHz) and larger die (335 mm² vs 263 mm²) do not translate into benchmark wins. The card’s only advantage is in DirectX 9, which is rarely used in modern applications. Its lower FP32 performance (13.31 TFLOPS vs 17.04 TFLOPS) and older RDNA 2.0 architecture place it at a clear disadvantage. Users who exclusively run legacy DirectX 9 software might consider this card, but for everyone else, the benchmark results indicate the NVIDIA GPU is the better investment. The data shows a decisive, if narrow in aggregate, victory for the RTX 5070 Ti Mobile.
