AMD Radeon RX 6800S vs NVIDIA Quadro M4000M Comparison

# AMD Radeon RX 6800S vs NVIDIA Quadro M4000M

The AMD Radeon RX 6800S and NVIDIA Quadro M4000M represent two very different eras of mobile graphics. The RX 6800S, a RDNA 2.0 part from the Radeon RX 6000 series, is built for gaming laptops with modern feature support. The Quadro M4000M, a Maxwell 2.0 professional mobile GPU, targets workstation use from an earlier generation. The recorded data shows a decisive performance gap: the RX 6800S achieves an average benchmark score of 24,063 versus 20,480 for the Quadro M4000M, placing the AMD part at the 69th percentile of all GPUs while the NVIDIA part sits at the 65th percentile. In the two directly comparable benchmark tests, the RX 6800S wins both, making the comparison straightforward from a raw performance standpoint.

Where Each One Wins

The RX 6800S wins on every benchmark where both GPUs have recorded scores. In Geekbench OpenCL, the AMD part scores 73,202 against 19,989 for the Quadro M4000M, a delta of 266.2 percent. In Geekbench Vulkan, the RX 6800S scores 81,272 versus 20,971, a delta of 287.5 percent. There are no test categories where the Quadro M4000M comes out ahead.

The RX 6800S also has a broader benchmark footprint in the database. It has recorded scores across 3DMark Steel Nomad DX12, Geekbench Metal, OpenCL, Vulkan, and multiple Passmark tests (DirectX 9, 10, 11, 12, G2D, G3D, and GPU compute). The Quadro M4000M only has two recorded scores, both in Geekbench. This means the RX 6800S can be evaluated across a wider range of workloads, while the Quadro M4000M's data is limited to compute and graphics API tests.

For users who prioritize modern API support, the RX 6800S is the clear choice. It supports DirectX 12 Ultimate (12_2), while the Quadro M4000M only reaches DirectX 12 (12_1). The RX 6800S also includes hardware ray tracing cores (32 of them), which the Quadro M4000M lacks entirely. The RX 6800S supports Vulkan 1.4 and OpenGL 4.6, matching the Quadro M4000M on those APIs, but the AMD part adds the full 12 Ultimate feature set.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The RX 6800S uses AMD's RDNA 2.0 architecture on a 7 nm TSMC process, while the Quadro M4000M uses NVIDIA's Maxwell 2.0 architecture on a 28 nm TSMC process. This node difference is significant: the RX 6800S packs 11,060 million transistors into a 237 mm² die, yielding a transistor density of 46.7 million per mm². The Quadro M4000M has 5,200 million transistors on a 398 mm² die, for a density of 13.1 million per mm². The RX 6800S achieves over three times the transistor density, which explains its much higher performance despite a similar power envelope.

Both GPUs have a 100 W TDP, but the RX 6800S delivers 8.602 TFLOPS of FP32 compute versus 2.593 TFLOPS for the Quadro M4000M. The AMD part also supports FP16 at 17.20 TFLOPS (2:1 ratio), while the Quadro M4000M has no recorded FP16 capability.

Memory configurations differ substantially. The RX 6800S has 8 GB of GDDR6 on a 128-bit bus, providing 256.0 GB/s of bandwidth. The Quadro M4000M has 4 GB of GDDR5 on a 256-bit bus, delivering 160.4 GB/s. Despite the narrower bus, the RX 6800S still offers 60 percent more memory bandwidth due to the faster GDDR6 memory running at 16 Gbps effective versus 5 Gbps effective for the Quadro M4000M.

The RX 6800S has 2048 shading units, 128 TMUs, and 64 ROPs, along with 32 ray tracing cores. The Quadro M4000M has 1280 shading units, 80 TMUs, and 64 ROPs. The pixel rate for the RX 6800S is 134.4 GPixel/s versus 64.83 GPixel/s for the Quadro M4000M. The texture rate is 268.8 GTexel/s versus 81.04 GTexel/s. The RX 6800S also uses a PCIe 4.0 x8 interface, while the Quadro M4000M uses PCIe 3.0 x16.

The RX 6800S is an IGP (integrated into the laptop motherboard), while the Quadro M4000M is an MXM module. The RX 6800S was released on January 3, 2022, while the Quadro M4000M came out on August 17, 2015. The AMD part is the successor to Polaris Mobile, while the Quadro M4000M is the successor to Quadro Kepler-M and was itself succeeded by Quadro Pascal-M.

Head-to-Head Benchmarks

The database records two direct head-to-head comparisons. In Geekbench OpenCL, the RX 6800S scores 73,202 against 19,989 for the Quadro M4000M. This is a 266.2 percent advantage, meaning the AMD part delivers roughly 3.7 times the OpenCL compute performance. OpenCL is often used for general-purpose GPU compute, so this gap reflects the RX 6800S's far higher FP32 throughput and memory bandwidth.

In Geekbench Vulkan, the RX 6800S scores 81,272 against 20,971 for the Quadro M4000M, a 287.5 percent advantage. The Vulkan test measures graphics API performance, and the RX 6800S's lead here is even larger than in OpenCL. This suggests the RDNA 2.0 architecture handles modern low-level graphics APIs more efficiently than Maxwell 2.0.

The RX 6800S also has scores in other tests that the Quadro M4000M does not have recorded. In 3DMark Steel Nomad DX12, it scores 1,689. In Geekbench Metal, it scores 85,256. Passmark results include 91 in DirectX 10, 139 in DirectX 11, 65 in DirectX 12, 200 in DirectX 9, 732 in G2D, 15,908 in G3D, and 6,144 in GPU compute. These additional data points show the RX 6800S is competitive across legacy and modern APIs, though the Quadro M4000M cannot be directly compared on these tests due to missing data.

Looking at the nearest rivals for context, the RX 6800S sits within 1 percent of several desktop GPUs: it is 0.4 percent behind the GeForce RTX 2080 SUPER, 0.7 percent behind the GTX 780 Ti, 0.8 percent ahead of the Radeon RX 9070, and 0.9 percent behind the GTX 1630. The Quadro M4000M also sits within about 1 percent of its nearest rivals: 0.3 percent behind the RTX 3070 Mobile, 0.4 percent behind the Intel Arc B570, 0.5 percent behind the Intel Arc A750, and 0.9 percent behind the Radeon R9 M390X. This shows both GPUs are clustered tightly with their peers, but the RX 6800S operates in a higher performance tier overall.

The Verdict

The data is unambiguous: the AMD Radeon RX 6800S outperforms the NVIDIA Quadro M4000M in every recorded benchmark. The RX 6800S has a higher average benchmark score (24,063 versus 20,480), a higher percentile rank (69th versus 65th), and wins both direct head-to-head tests by margins exceeding 266 percent.

For users seeking maximum graphics and compute performance in a mobile platform, the RX 6800S is the only choice based on this data. It offers more than triple the FP32 compute throughput, 60 percent more memory bandwidth, double the VRAM capacity, and support for DirectX 12 Ultimate and hardware ray tracing. The Quadro M4000M, while a capable professional GPU in its era, is outclassed by a generation gap of over six years and a fundamental architecture shift.

The Quadro M4000M might still be relevant for legacy workstation software that relies on specific NVIDIA professional drivers, but the benchmark data does not show any performance advantage. Its 64 ROPs match the RX 6800S, but every other compute metric favors the AMD part. The Quadro M4000M also has a narrower benchmark footprint, making it harder to assess across varied workloads.

For users who need modern API support, high memory bandwidth, or ray tracing, the RX 6800S is the clear pick. For users who are constrained to MXM modules or require a specific professional GPU lineage, the Quadro M4000M exists, but the performance gap is so large that it should only be considered if compatibility requirements override raw performance.
