AMD Radeon RX 6700S vs NVIDIA Quadro M4000M Comparison

The AMD Radeon RX 6700S is decisively the faster mobile GPU, leading the NVIDIA Quadro M4000M by a wide margin in every shared benchmark. The data shows a generational leap, with the RX 6700S delivering over 3.5x the compute performance in OpenCL and Vulkan tests, making it the clear choice for modern workloads. The Quadro M4000M, while still holding a respectable 65th percentile rank among all GPUs, is limited by its older architecture and smaller memory pool, positioning it as a legacy option for compatibility-focused tasks.

Where Each One Wins

The AMD Radeon RX 6700S wins in every measurable performance category where both cards have been tested. Its 2-win head-to-head record confirms absolute dominance in compute and graphics API benchmarks. The RX 6700S achieves a 255% higher score in Geekbench OpenCL and a 263.1% higher score in Geekbench Vulkan, demonstrating that it is not merely faster but operates in an entirely different performance class. This makes it the superior choice for any application that leverages OpenCL or Vulkan, including modern game engines, content creation suites, and GPU-accelerated compute tasks.

The NVIDIA Quadro M4000M, conversely, finds its niche not through performance wins but through its legacy positioning. It holds a 65th percentile rank versus the RX 6700S's 67th percentile, showing it remains relevant in the broader GPU ecosystem. Its 4 GB memory and Maxwell 2.0 architecture suggest it was designed for professional workstation applications of its era, such as CAD and certified ISV workloads that may rely on older driver optimizations. However, the benchmark data provides no evidence of any workload where the M4000M outperforms the RX 6700S; its "win" is purely in the context of being an end-of-life product that still functions for legacy software environments.

The Verdict

From the data, the choice is unambiguous: the AMD Radeon RX 6700S is the GPU to select for any user prioritizing raw performance, modern API support, and future-proofing. Its average benchmark score of 22154 places it within 0.1% of the AMD Radeon RX 5700 and 1.3% of the NVIDIA GeForce RTX 5060 Mobile, showing it competes with much newer discrete desktop and mobile parts. The RX 6700S also offers 8 GB of GDDR6 memory, double the M4000M's capacity, which is critical for modern high-resolution textures and large datasets.

The NVIDIA Quadro M4000M should only be considered by users with a specific, legacy requirement. Its 20480 average benchmark score is surprisingly close to the NVIDIA GeForce RTX 3070 Mobile (0.3% difference), but this is a statistical anomaly given its older architecture. The M4000M's 160.4 GB/s bandwidth and 2.593 TFLOPS FP32 performance are dwarfed by the RX 6700S's 224.0 GB/s and 7.168 TFLOPS. For any new purchase or upgrade, the RX 6700S is the only rational choice based on performance data; the M4000M is a relic for niche compatibility scenarios where its specific driver support is mandatory.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows the most extreme gap. The AMD Radeon RX 6700S scores 70965, while the NVIDIA Quadro M4000M scores 19989, a 255% difference. This result reflects the fundamental architectural advantages of the RX 6700S: its 1792 shading units versus 1280, its 7 nm process versus 28 nm, and its RDNA 2.0 design which offers significantly higher instruction-level efficiency than Maxwell 2.0. The M4000M's FP32 throughput of 2.593 TFLOPS is simply overwhelmed by the RX 6700S's 7.168 TFLOPS.

The Vulkan benchmark reinforces this narrative with an even larger margin. The RX 6700S hits 76150, against the M4000M's 20971, for a 263.1% delta. Vulkan is a low-overhead API that scales well with raw compute resources, and the RX 6700S's modern architecture excels here. The M4000M's 4 GB memory may also cause bottlenecks in Vulkan workloads that allocate larger buffers, further widening the gap. Notably, the RX 6700S also supports DirectX 12 Ultimate (12_2) with hardware ray tracing cores, while the M4000M is limited to DirectX 12 (12_1), a feature gap that cannot be bridged by driver updates.

Architecture Differences

The architectural chasm between these two GPUs is vast. The AMD Radeon RX 6700S uses the Navi 23 chip built on TSMC's 7 nm process, containing 11,060 million transistors on a 237 mm² die. This yields a transistor density of 46.7M per mm², a staggering figure enabled by modern manufacturing. The NVIDIA Quadro M4000M, by contrast, uses the GM204 chip on TSMC's older 28 nm process, packing 5,200 million transistors on a much larger 398 mm² die, resulting in a density of just 13.1M per mm². This difference alone explains the massive performance and efficiency gap.

The RX 6700S features RDNA 2.0 architecture with 1792 shading units, 112 texture mapping units, and 64 ROPs. It also includes 28 dedicated ray tracing cores, a feature completely absent from the M4000M. The NVIDIA card uses Maxwell 2.0 with 1280 shading units, 80 TMUs, and 64 ROPs. In terms of compute, the RX 6700S delivers 7.168 TFLOPS FP32 and 14.34 TFLOPS FP16 (2:1), while the M4000M offers only 2.593 TFLOPS FP32 with no FP16 support listed. The RX 6700S also has higher pixel and texture rates: 128.0 GPixel/s and 224.0 GTexel/s versus 64.83 GPixel/s and 81.04 GTexel/s.

Specification Differences

The most critical specification difference is memory. The RX 6700S has 8 GB of GDDR6 on a 128-bit bus, providing 224.0 GB/s of bandwidth. The M4000M has 4 GB of GDDR5 on a wider 256-bit bus, but only achieves 160.4 GB/s due to slower memory clocks. Clock speeds also differ significantly: the RX 6700S has a base clock of 1700 MHz and boost of 2000 MHz, while the M4000M runs at a modest 975 MHz base and 1013 MHz boost. The AMD card's memory runs at 1750 MHz (14 Gbps effective), versus 1253 MHz (5 Gbps effective) for the NVIDIA.

Power and form factor further differentiate them. The RX 6700S has a TDP of 80 W and is an integrated GPU (IGP) with no power connectors, making it suitable for thin laptops. The M4000M has a higher TDP of 100 W and uses an MXM Module form factor, indicating it was designed for larger, more upgradeable mobile workstations. The RX 6700S uses a PCIe 4.0 x8 interface, while the M4000M uses the older PCIe 3.0 x16. Both are end-of-life products, but the RX 6700S was released in January 2022 versus August 2015 for the M4000M, which also has a successor (Quadro Pascal-M) whereas the RX 6700S does not.
