AMD Radeon RX 6750 XT vs AMD Radeon RX 9070 Comparison

Head-to-Head Benchmarks

The RX 9070 dominates the head-to-head comparison, winning 8 of 10 benchmark tests against the RX 6750 XT. The largest victory comes in Geekbench OpenCL, where the RX 9070 scores 131,539 against 16,360 for the RX 6750 XT, a 87.6% advantage. This is a generational leap in raw compute throughput that reflects the fundamental architectural shift between RDNA 2.0 and RDNA 4.0.

The 3DMark Steel Nomad DX12 test tells a similar story, with the RX 9070 posting 6,290 points versus 2,548 for the RX 6750 XT, a 59.5% margin. This is the most modern gaming workload in the benchmark suite, and the RX 9070's lead here indicates that the newer architecture scales far better with contemporary rendering techniques. The PassMark G3D score also favors the RX 9070 at 25,381 versus 20,700, an 18.4% advantage, though this is a smaller gap than the more specialized tests suggest.

Compute-heavy workloads show the RX 9070's strength most clearly. In PassMark GPU Compute, the RX 9070 achieves 14,737 against 9,550, a 35.2% lead. The PassMark DirectX 11 test shows a 35.9% advantage for the RX 9070 (281 vs 180), and DirectX 9 shows a 23.3% edge (343 vs 263). The RX 9070 also wins PassMark DirectX 10 by 11.3% (141 vs 125) and PassMark G2D by 24.1% (1,280 vs 972).

However, the RX 6750 XT claims two notable victories. In Geekbench Vulkan, it scores 98,089 against 58,705 for the RX 9070, a 67.1% advantage. This is a striking reversal given the RX 9070's dominance elsewhere, suggesting that the older card's Vulkan driver path or architecture handles certain low-level API workloads more efficiently. The RX 6750 XT also edges out the RX 9070 in PassMark DirectX 12 by 8.1% (80 vs 74), though both scores are low in absolute terms and this test may not be representative of real-world DX12 performance.

The average benchmark score paints a different picture than the head-to-head results. The RX 6750 XT has an average score of 26,011 across all benchmarks, placing it at the 71st percentile of all GPUs, while the RX 9070 averages 23,877 and sits at the 69th percentile. This discrepancy arises because the RX 6750 XT's massive Vulkan score inflates its average, while the RX 9070's Geekbench OpenCL result is its only extreme outlier. The RX 6750 XT's nearest rivals include the AMD Radeon R9 M395X (0.5% ahead), AMD FirePro W7100 (0.6% ahead), and NVIDIA GeForce RTX 3080 Ti Mobile (1.1% ahead). The RX 9070's nearest rivals include the NVIDIA GeForce GTX TITAN Z (0.6% ahead) and AMD Radeon RX 6800S (0.8% behind).

Architecture Differences

The architectural gap between these two GPUs is substantial. The RX 6750 XT uses the Navi 22 chip built on RDNA 2.0 architecture, manufactured on TSMC's 7 nm process. The RX 9070 uses the Navi 48 chip with RDNA 4.0 architecture, fabricated on TSMC's 4 nm process. This process shrink enables a dramatic increase in transistor count: the RX 9070 packs 53,900 million transistors versus 17,200 million for the RX 6750 XT, despite a nearly identical die size (357 mm² vs 335 mm²). Transistor density jumps from 51.3 million per square millimeter to 151.0 million, a 3x improvement.

The RX 9070's compute resources scale accordingly. It features 3,584 shading units, 224 texture mapping units, and 128 ROPs, compared to 2,560 shading units, 160 TMUs, and 64 ROPs on the RX 6750 XT. Ray tracing cores increase from 40 to 56. This translates to a massive FP32 throughput advantage: 36.13 TFLOPS for the RX 9070 versus 13.31 TFLOPS for the RX 6750 XT. Notably, the RX 9070's FP16 performance equals its FP32 at 36.13 TFLOPS (1:1 ratio), while the RX 6750 XT delivers FP16 at 26.62 TFLOPS (2:1 ratio), indicating a different compute path for half-precision workloads.

Clock speeds tell a more nuanced story. The RX 6750 XT has a higher base clock at 2,150 MHz and a higher boost clock at 2,600 MHz, while the RX 9070 runs at 1,330 MHz base and 2,520 MHz boost. The RX 9070's game clock is also lower at 2,070 MHz versus 2,495 MHz. Despite lower clocks, the RX 9070 achieves higher pixel and texture rates (322.6 GPixel/s and 564.5 GTexel/s vs 166.4 and 416.0 respectively) due to its wider execution resources.

Memory subsystems differ as well. The RX 9070 has 16 GB of GDDR6 on a 256-bit bus delivering 644.6 GB/s bandwidth, while the RX 6750 XT has 12 GB on a 192-bit bus at 432.0 GB/s. Memory clock rates are 2,518 MHz (20.1 Gbps effective) for the RX 9070 versus 2,250 MHz (18 Gbps effective) for the RX 6750 XT. The RX 9070 also upgrades the bus interface to PCIe 5.0 x16 from PCIe 4.0 x16.

Where Each One Wins

The RX 9070 is the clear winner for modern gaming and compute workloads. Its 59.5% lead in 3DMark Steel Nomad DX12 indicates superior performance in current-generation DX12 titles that leverage advanced features. The 87.6% advantage in Geekbench OpenCL makes it the obvious choice for GPU compute tasks such as rendering, scientific simulation, or machine learning workloads that rely on OpenCL. Its 35.2% lead in PassMark GPU Compute reinforces this conclusion. For legacy DirectX 9 and DirectX 11 titles, the RX 9070's 23.3% and 35.9% advantages respectively show that it handles older APIs well despite its newer architecture.

The RX 6750 XT wins in Geekbench Vulkan by 67.1%, which suggests it may be preferable for Vulkan-based applications or games that are heavily optimized for that API. Its 8.1% edge in PassMark DirectX 12, while small, indicates that some DX12 workloads may still favor the older card. The RX 6750 XT's higher boost clock of 2,600 MHz versus 2,520 MHz could contribute to its performance in latency-sensitive or lightly threaded scenarios where clock speed matters more than raw throughput.

For users considering overall benchmark standing, the RX 6750 XT's 71st percentile ranking versus the RX 9070's 69th percentile is noteworthy, though this is heavily influenced by the Vulkan outlier. The RX 9070's average score is pulled down by its relatively low Vulkan result, but its wins in 8 of 10 head-to-head tests make it the more consistent performer.

Specification Differences

The two cards differ across nearly every specification category.

The Verdict

The data clearly favors the RX 9070 for most use cases. It wins 8 of 10 head-to-head benchmarks, with particularly decisive margins in modern workloads like 3DMark Steel Nomad DX12 (59.5% ahead) and Geekbench OpenCL (87.6% ahead). Its 16 GB memory capacity, higher bandwidth, and 36.13 TFLOPS FP32 performance make it the stronger choice for current and future gaming, content creation, and compute tasks. The 4 nm process and RDNA 4.0 architecture deliver substantially more transistors (53,900 million vs 17,200 million) in a similar die size, enabling a 2.7x increase in FP32 throughput despite lower clock speeds.

The RX 6750 XT remains relevant only for specific scenarios. Its 67.1% Vulkan advantage suggests it may be preferable for Vulkan-based applications, and its 8.1% DirectX 12 win shows some DX12 workloads still favor it. Its higher boost clock of 2,600 MHz could benefit certain latency-sensitive workloads. However, its end-of-life production status and lower memory capacity (12 GB vs 16 GB) limit its future-proofing.

For most buyers, the RX 9070 is the logical choice given its overwhelming benchmark dominance and active production status. The RX 6750 XT's higher average benchmark score and percentile ranking are artifacts of its Vulkan outlier and do not outweigh the RX 9070's consistency across the benchmark suite. Users with specific Vulkan-heavy workloads or those constrained by power delivery (the RX 6750 XT has a lower TDP of 220 W vs 250 W) might consider the older card, but the data supports the RX 9070 as the superior all-around GPU.
