AMD Radeon RX 6700 XT vs AMD Radeon RX 6750 XT Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear overall victory for the AMD Radeon RX 6750 XT, which wins 10 of the 11 head-to-head comparisons. The most decisive win for the RX 6750 XT comes in the Passmark DirectX 9 test, where it scores 263 against the RX 6700 XT's 242 — an 8% advantage. That legacy API performance gap is notable, as it suggests the newer card handles older workloads with more headroom.

Across modern DirectX 12 and Vulkan workloads, the RX 6750 XT maintains a consistent edge. In the 3DMark Steel Nomad DX12 test, the RX 6750 XT scores 2548 versus 2435 for the RX 6700 XT, a 4.4% lead. The Vulkan results tell a similar story: 98089 for the RX 6750 XT against 93500, a 4.7% advantage. The Geekbench Metal benchmark also favors the RX 6750 XT, with a score of 137249 compared to 130896, a 4.6% gap. In the Passmark G3D suite, the RX 6750 XT posts 20700 versus 19786, again a 4.4% difference.

The RX 6700 XT's sole victory is a dramatic one in the Geekbench OpenCL test, where it scores 44152 against the RX 6750 XT's 16360. That 169.9% margin is the largest delta in either direction across the entire benchmark suite. It is an outlier, however, and likely reflects driver or workload-specific behavior rather than a general compute advantage.

The remaining Passmark tests show smaller but consistent wins for the RX 6750 XT: DirectX 10 (125 vs 124, a 0.8% margin), DirectX 11 (180 vs 173, a 3.9% margin), DirectX 12 (80 vs 77, a 3.7% margin), G2D (972 vs 951, a 2.2% margin), and GPU Compute (9550 vs 9336, a 2.2% margin). The aggregate picture is unambiguous: the RX 6750 XT is the faster card in almost every measurable scenario, with gains ranging from marginal to substantial.

It is importantly the RX 6700 XT's average benchmark score of 27425 actually exceeds the RX 6750 XT's average of 26011. This discrepancy is driven entirely by that OpenCL outlier; when the average is computed across all tests, the RX 6700 XT's massive OpenCL score inflates its mean. The percentile rankings tell a different story: the RX 6700 XT sits at the 72nd percentile against all GPUs, while the RX 6750 XT sits at the 71st. The RX 6700 XT's nearest rival is the NVIDIA GeForce RTX 4070 Mobile with an average score of 27435, a 0% delta, followed by the NVIDIA GeForce RTX 3090 at 27565, a -0.5% delta. The RX 6750 XT's nearest rivals are considerably lower-ranked, with the AMD Radeon R9 M395X at 25891 (0.5% delta) and the AMD FirePro W7100 at 25856 (0.6% delta).

Architecture Differences

Both cards are built on the same fundamental architecture: RDNA 2.0, fabricated on TSMC's 7 nm process, with the Navi 22 chip. The transistor count is identical at 17,200 million, and the die size is the same 335 mm², yielding a transistor density of 51.3M per mm². Both belong to the Navi II (RX 6000) generation and share the same predecessor (Navi) and successor (Navi III).

The core configurations are also identical: 2560 shading units, 160 texture mapping units, 64 raster operations pipelines, and 40 ray tracing cores. Neither card has tensor cores. The pixel rate is nearly the same — 165.2 GPixel/s for the RX 6700 XT and 166.4 GPixel/s for the RX 6750 XT — as is the texture rate at 413.0 GTexel/s versus 416.0 GTexel/s. The FP32 compute figures are close: 13.21 TFLOPS for the RX 6700 XT and 13.31 TFLOPS for the RX 6750 XT, with FP16 at 26.43 TFLOPS and 26.62 TFLOPS respectively, both at a 2:1 ratio.

The differences begin with clock speeds. The RX 6700 XT has a higher base clock at 2321 MHz versus 2150 MHz for the RX 6750 XT. However, the RX 6750 XT has a higher boost clock at 2600 MHz versus 2581 MHz, and a higher game clock at 2495 MHz versus 2424 MHz. The memory clocks diverge more significantly: the RX 6700 XT runs its GDDR6 at 2000 MHz (16 Gbps effective), while the RX 6750 XT runs at 2250 MHz (18 Gbps effective). This yields a memory bandwidth of 384.0 GB/s for the RX 6700 XT and 432.0 GB/s for the RX 6750 XT — a 12.5% improvement for the newer card.

Memory capacity and bus width are identical: 12 GB of GDDR6 on a 192-bit interface. The power envelope differs, with the RX 6700 XT rated at 230 W TDP and the RX 6750 XT at 250 W. The suggested power supply rating also increases from 550 W to 600 W. Both cards use the same power connectors (1x 6-pin + 1x 8-pin) and are dual-slot designs. Physical dimensions match exactly: 267 mm in length, 110 mm in height, and 40 mm in width.

The API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs are the same as well: 1x HDMI 2.1 and 3x DisplayPort 1.4a. Both use a PCIe 4.0 x16 bus interface. The release dates differ by one year — the RX 6700 XT launched on March 2, 2021, and the RX 6750 XT on March 2, 2022. Both are now end-of-life products.

FAQ

Q: How do the cards compare in Vulkan performance?

A: The RX 6750 XT wins the Geekbench Vulkan test with a score of 98089, compared to 93500 for the RX 6700 XT — a 4.7% difference.

Q: Is there any test where the RX 6700 XT wins?

A: Yes, the RX 6700 XT wins the Geekbench OpenCL test by a wide margin, scoring 44152 against the RX 6750 XT's 16360. That is a 169.9% advantage, the largest delta in any benchmark between the two cards.

Q: Do the cards have the same memory configuration?

A: Both have 12 GB of GDDR6 on a 192-bit bus, but the memory speed differs. The RX 6700 XT runs at 2000 MHz (16 Gbps effective) with 384.0 GB/s bandwidth, while the RX 6750 XT runs at 2250 MHz (18 Gbps effective) with 432.0 GB/s bandwidth.

Q: Which card has a higher boost clock?

A: The RX 6750 XT has a higher boost clock at 2600 MHz, compared to 2581 MHz for the RX 6700 XT. However, the RX 6700 XT has a higher base clock at 2321 MHz versus 2150 MHz.

Q: How do their average benchmark scores compare?

A: The RX 6700 XT has a higher average benchmark score of 27425, while the RX 6750 XT averages 26011. This is skewed by the RX 6700 XT's outlier OpenCL result; the RX 6750 XT wins 10 of 11 individual tests.

The Verdict

The data points to a straightforward conclusion: the AMD Radeon RX 6750 XT is the better-performing card in nearly every benchmark. It wins 10 of 11 head-to-head comparisons, with margins ranging from 0.8% in Passmark DirectX 10 to 8% in Passmark DirectX 9. Its advantages in modern APIs — 4.4% in DirectX 12, 4.7% in Vulkan, and 4.6% in Metal — make it the stronger choice for contemporary gaming and compute workloads.

The RX 6700 XT's single victory in Geekbench OpenCL, while massive at 169.9%, appears anomalous and should not be weighted heavily in a purchasing decision. Its higher average benchmark score is a statistical artifact of that outlier, not evidence of general superiority.

For buyers prioritizing consistent performance across a wide range of tests, the RX 6750 XT is the clear pick. It also offers higher memory bandwidth (432.0 GB/s versus 384.0 GB/s), a higher game clock, and a higher boost clock, despite its lower base clock. The trade-off is a 20 W increase in TDP and a 50 W increase in suggested PSU rating, which may matter for systems with tighter power budgets.

The RX 6700 XT retains a niche appeal for users who specifically need raw OpenCL compute performance, where its 44152 score dwarfs the RX 6750 XT's 16360. For everyone else, the RX 6750 XT's broader benchmark dominance makes it the more capable and versatile card. Both are end-of-life products, but the RX 6750 XT's year-later release and higher launch MSRP reflect its position as the refined, higher-performance variant of the same architecture.
