Architecture Differences

Both the AMD Radeon RX 6700 and AMD Radeon RX 6750 XT belong to the Radeon RX 6000 series, sharing the Navi 22 chip, RDNA 2.0 architecture, and the TSMC 7 nm process node. The die size is identical at 335 mm², with 17,200 million transistors and a transistor density of 51.3M per mm². The architectural foundation is the same, but the RX 6750 XT comes with more compute resources enabled.

The RX 6700 has 2304 shading units, 144 texture mapping units, and 64 raster operations units. The RX 6750 XT scales this up to 2560 shading units, 160 TMUs, and also 64 ROPs. The ray tracing hardware follows the same pattern: the RX 6700 has 36 RT cores, while the RX 6750 XT has 40 RT cores. Neither card includes tensor cores.

Clock speeds differ significantly. The RX 6700 runs at a 1941 MHz base clock, 2174 MHz game clock, and 2450 MHz boost clock. The RX 6750 XT is substantially higher in all three: 2150 MHz base, 2495 MHz game, and 2600 MHz boost. Memory clocks also differ, with the RX 6700 at 2000 MHz (16 Gbps effective) and the RX 6750 XT at 2250 MHz (18 Gbps effective).

The memory subsystem is a major architectural divergence. The RX 6700 uses 10 GB of GDDR6 on a 160-bit bus, yielding 320.0 GB/s of bandwidth. The RX 6750 XT uses 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. This 112 GB/s difference in bandwidth is directly attributable to the wider bus and faster memory clock.

Compute throughput scales with the shader count and clocks. The RX 6700 delivers 11.29 TFLOPS FP32 and 22.58 TFLOPS FP16 (2:1 ratio). The RX 6750 XT reaches 13.31 TFLOPS FP32 and 26.62 TFLOPS FP16. Pixel fill rates are 156.8 GPixel/s versus 166.4 GPixel/s, and texture rates are 352.8 GTexel/s versus 416.0 GTexel/s. Both cards share the same PCIe 4.0 x16 interface, API support (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), and dual-slot design.

Head-to-Head Benchmarks

The head-to-head data shows a clear pattern: the RX 6750 XT wins 10 of 11 tests, while the RX 6700 takes only one. The largest margin belongs to the RX 6700 in Geekbench OpenCL, where it scores 97841 against the RX 6750 XT's 16360, a 498.1% lead. This is an outlier, likely reflecting a specific driver or workload interaction rather than general compute superiority.

In the 3DMark Steel Nomad DX12 test, the RX 6750 XT scores 2548 versus 2014, a 21% advantage. This is one of the largest wins for the newer card and indicates a meaningful performance gap in modern graphics workloads. The Geekbench Vulkan test shows a 14.4% lead for the RX 6750 XT (98089 vs 83974), and the Metal test shows a 10.9% lead (137249 vs 122223).

PassMark results are more moderate but consistently favor the RX 6750 XT. The DirectX 12 test shows 80 versus 71, an 11.2% difference. DirectX 11 shows 180 versus 166, a 7.8% lead. DirectX 10 shows 125 versus 115, an 8% lead. DirectX 9 shows 263 versus 250, a 4.9% lead. The G3D test shows 20700 versus 18931, an 8.5% lead. GPU compute shows 9550 versus 8240, a 13.7% lead. The G2D test is closest, with 972 versus 936, a 3.7% lead.

The overall picture is that the RX 6750 XT is faster across nearly every API and workload type, with margins ranging from 3.7% to 21% in its wins. The RX 6700's single victory is so lopsided that it dominates the average score calculation, but it does not represent a practical advantage in gaming or general-purpose compute.

Specification Differences

The two cards differ in several key specifications beyond the benchmarks. The RX 6750 XT has 2560 shading units versus 2304, 160 TMUs versus 144, and 40 RT cores versus 36. The ROP count is identical at 64.

Clock speeds are higher on the RX 6750 XT in every measure: base clock is 2150 MHz versus 1941 MHz, game clock is 2495 MHz versus 2174 MHz, and boost clock is 2600 MHz versus 2450 MHz. The memory clock is 2250 MHz versus 2000 MHz, with effective speeds of 18 Gbps versus 16 Gbps.

Memory capacity and bus width differ: 12 GB on a 192-bit bus versus 10 GB on a 160-bit bus. This results in bandwidth of 432.0 GB/s versus 320.0 GB/s. The power envelope is also different, with the RX 6750 XT rated at 250 W TDP versus 175 W for the RX 6700. The power connectors reflect this: the RX 6750 XT uses 1x 6-pin plus 1x 8-pin, while the RX 6700 uses a single 8-pin. The suggested PSU is 600 W versus 450 W.

Compute rates scale accordingly: FP32 is 13.31 TFLOPS versus 11.29 TFLOPS, FP16 is 26.62 TFLOPS versus 22.58 TFLOPS. Pixel rate is 166.4 GPixel/s versus 156.8 GPixel/s, and texture rate is 416.0 GTexel/s versus 352.8 GTexel/s.

Physical dimensions are identical: 267 mm length, 110 mm height, and 40 mm width. Both are dual-slot cards with the same display outputs: 1x HDMI 2.1 and 3x DisplayPort 1.4a. The release dates differ, with the RX 6700 launching on 2021-06-08 and the RX 6750 XT on 2022-03-02. Both are end-of-life production status. The RX 6750 XT has a launch MSRP of 549 USD.

The Verdict

The data points to the RX 6750 XT as the stronger performer in almost every measured scenario. It wins 10 of 11 head-to-head benchmarks, with the largest margin being 21% in 3DMark Steel Nomad DX12 and the smallest being 3.7% in PassMark G2D. It also offers 12 GB of memory versus 10 GB, higher bandwidth, and more compute units.

However, the RX 6700 holds a curious advantage in the average benchmark score, 30433 versus 26011, driven by its extraordinary Geekbench OpenCL result. This makes the RX 6700 rank higher, at the 75th percentile versus the 71st percentile. Its nearest rivals include the NVIDIA CMP 70HX and Tesla M60, while the RX 6750 XT sits near mobile-class GPUs like the RTX 3080 Ti Mobile.

For buyers prioritizing raw benchmark averages, the RX 6700 appears better. For those looking at actual graphics workloads, the RX 6750 XT is consistently ahead. The RX 6700 requires less power (175 W vs 250 W) and a smaller PSU (450 W vs 600 W), which could be a deciding factor in constrained builds.

The RX 6750 XT costs more, given its launch MSRP of 549 USD, but the performance delta in gaming and standard compute tests justifies the positioning for most users. The RX 6700 is a reasonable choice for scenarios where OpenCL compute is paramount, as its 498.1% advantage in that test is unprecedented.

Where Each One Wins

The RX 6750 XT is the clear winner in DirectX workloads. It leads by 21% in Steel Nomad DX12, 11.2% in PassMark DirectX 12, and 7.8% in DirectX 11. It also wins in Vulkan (14.4%), Metal (10.9%), and all PassMark graphics tests. For gaming, modern API usage, and general GPU compute, the RX 6750 XT is the recommended pick based on the recorded data.

The RX 6700 wins decisively in Geekbench OpenCL, outperforming the RX 6750 XT by 498.1%. This makes it the better option for OpenCL-specific compute tasks, such as certain scientific or professional workloads that rely heavily on that API. Its lower power draw and lower PSU requirement also make it suitable for systems with modest power delivery.

For users who value average benchmark scores as a composite metric, the RX 6700's 30433 average exceeds the RX 6750 XT's 26011, placing it in a higher percentile. This could matter in comparative rankings, even if individual tests tell a different story.

The RX 6750 XT also offers more memory (12 GB vs 10 GB) and higher bandwidth (432.0 GB/s vs 320.0 GB/s), which could benefit texture-heavy workloads and higher resolutions. The RX 6700's smaller footprint in terms of power consumption (175 W vs 250 W) makes it easier to integrate into existing systems without upgrading the PSU.

In summary, pick the RX 6750 XT for gaming and mainstream compute, and pick the RX 6700 only if OpenCL performance or lower power requirements are the primary constraints.
