AMD Radeon RX 6850M XT vs AMD Radeon RX 9070 GRE Comparison

Head-to-Head Benchmarks

The recorded data contains two shared benchmark results for these GPUs, and the AMD Radeon RX 9070 GRE wins both. In the 3DMark Steel Nomad DX12 test, the RX 9070 GRE scores 5424, while the RX 6850M XT scores 2257. That is a 58.4% deficit for the mobile part, meaning the newer desktop card delivers more than double the raw performance in this DirectX 12 workload. The gap is substantial enough that the RX 6850M XT cannot be considered competitive in this specific test, regardless of its mobile design constraints.

The second shared test, Geekbench OpenCL, shows a narrower but still decisive margin. The RX 9070 GRE scores 109309, while the RX 6850M XT scores 85040. The delta is 22.2% in favor of the RX 9070 GRE. This test is more compute-oriented and less dependent on memory bandwidth or rasterization throughput, yet the newer architecture still pulls ahead by a clear margin. The RX 6850M XT has no recorded wins in the head-to-head data; the RX 9070 GRE wins both available comparisons.

Looking at the broader benchmark averages, the picture shifts somewhat. The RX 6850M XT has an average benchmark score of 78940 across all recorded tests, while the RX 9070 GRE averages 57367. That is a 37.6% advantage for the older mobile GPU in overall average score, which seems contradictory to the head-to-head results. The explanation lies in the benchmark sets: the RX 6850M XT has four recorded benchmarks including Geekbench Metal and Geekbench Vulkan, while the RX 9070 GRE has only two. The mobile part's average is boosted by its strong Metal and Vulkan results, which are not present in the desktop card's data. The head-to-head tests remain the only direct apples-to-apples comparison, and those favor the RX 9070 GRE in both cases.

In terms of percentile ranking, the RX 6850M XT sits at the 92nd percentile among all GPUs, while the RX 9070 GRE sits at the 87th. This means the mobile part ranks higher overall in the database, again reflecting its broader benchmark coverage. However, the direct comparison tests tell a different story, and those are the ones that matter when deciding between these two specific cards.

Where Each One Wins

The RX 9070 GRE wins in the two areas where both cards were measured under identical conditions. In 3DMark Steel Nomad DX12, its 5424 score versus 2257 represents a 58.4% lead, making it the clear choice for modern DirectX 12 gaming workloads that stress geometry, ray tracing, and mesh shading. In Geekbench OpenCL, its 109309 versus 85040 gives it a 22.2% lead, indicating superior general-purpose compute performance in OpenCL applications.

The RX 6850M XT does not win any head-to-head benchmark. Its advantages appear only in tests that the RX 9070 GRE was not subjected to. Specifically, the mobile card records a Geekbench Metal score of 128981 and a Geekbench Vulkan score of 99483. These are strong numbers, but without comparable RX 9070 GRE results in the database, they cannot be used to claim superiority. The mobile part also has a higher average benchmark score (78940 versus 57367) and a higher percentile rank (92 versus 87), but these metrics are skewed by the different test sets.

For users who rely on Metal-based applications, typically on macOS systems, the RX 6850M XT has demonstrated performance that the RX 9070 GRE has not been measured against. Similarly, Vulkan workloads show the mobile card at 99483, but again, there is no RX 9070 GRE Vulkan score in the data. The practical conclusion is that the RX 9070 GRE wins every direct comparison, while the RX 6850M XT only shows strengths in tests that lack a counterpart.

Architecture Differences

The two GPUs come from different architectural generations. The RX 6850M XT uses the Navi 22 chip built on RDNA 2.0, while the RX 9070 GRE uses Navi 48 built on RDNA 4.0. The process node tells a clear story: the RX 6850M XT is fabricated on TSMC's 7 nm process, whereas the RX 9070 GRE uses TSMC's 4 nm process. This node shrink allows the newer card to pack far more transistors into a similar die area. The RX 6850M XT has 17,200 million transistors on a 335 mm² die, giving a transistor density of 51.3 million per mm². The RX 9070 GRE has 53,900 million transistors on a 357 mm² die, a density of 151.0 million per mm². That is nearly three times the transistor density, which explains the large compute capability jump despite the modest die size increase.

The shader configuration differs significantly. The RX 6850M XT has 2560 shading units, 160 texture mapping units, and 64 raster output pipelines. The RX 9070 GRE has 3072 shading units, 192 TMUs, and 96 ROPs. The newer card also has more ray tracing cores: 48 versus 40. Neither card has tensor cores listed in the database. The pixel rate and texture rate reflect these differences. The RX 6850M XT outputs 165.2 GPixel/s and 413.0 GTexel/s, while the RX 9070 GRE reaches 267.8 GPixel/s and 535.7 GTexel/s. The RX 9070 GRE leads by 62.2% in pixel throughput and 29.7% in texture throughput.

Compute throughput shows the largest architectural leap. The RX 6850M XT delivers 13.21 TFLOPS of FP32 performance and 26.43 TFLOPS of FP16 with a 2:1 ratio. The RX 9070 GRE delivers 34.28 TFLOPS of FP32 and 34.28 TFLOPS of FP16 with a 1:1 ratio. That means the RX 9070 GRE has 159.5% more FP32 throughput and 29.7% more FP16 throughput. The 1:1 FP16 ratio on RDNA 4.0 indicates a shift toward unified compute paths, whereas RDNA 2.0 used a packed math approach for half-precision.

Memory configuration is identical in capacity, type, bus width, and bandwidth. Both cards use 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. The memory clock is also the same at 2250 MHz with 18 Gbps effective data rate. This means the memory subsystem is not a differentiator; all performance gains come from the compute architecture and clock speeds.

Clock speeds show a trade-off. The RX 6850M XT has a base clock of 2321 MHz, a boost clock of 2581 MHz, and a game clock of 2463 MHz. The RX 9070 GRE has a lower base clock of 1420 MHz but a higher boost clock of 2790 MHz, with a game clock of 2220 MHz. The mobile card runs at higher sustained clocks in its base and game states, but the desktop card's boost clock is higher. The power envelope differs accordingly: the RX 6850M XT has a TDP of 165 W, while the RX 9070 GRE draws 220 W.

The Verdict

The data points to the RX 9070 GRE as the stronger performer in direct comparisons. It wins both shared benchmarks, with leads of 58.4% in 3DMark Steel Nomad DX12 and 22.2% in Geekbench OpenCL. Its architectural advantages are substantial: a 4 nm process, 53,900 million transistors, 3072 shading units, 48 ray tracing cores, and 34.28 TFLOPS of FP32 compute. These are not marginal improvements; they represent a generational leap in raw throughput.

The RX 6850M XT retains a higher average benchmark score and percentile rank, but those figures come from a broader test set that includes Metal and Vulkan results. In the only tests where both cards were measured under identical conditions, the RX 9070 GRE wins decisively. Users who prioritize DirectX 12 gaming and OpenCL compute should choose the RX 9070 GRE. Users who specifically need Metal performance, or who require a mobile-integrated form factor without external power connectors, would look to the RX 6850M XT, though its end-of-life status and lower direct benchmark results limit its appeal. The RX 9070 GRE is the faster card where it matters most, and it is currently in active production with a 549 USD launch MSRP.
