GPU Comparison

The AMD Radeon RX 7900M and NVIDIA Quadro GP100 represent two distinct eras of GPU design, separated by seven years of architectural evolution. The data shows a single head-to-head benchmark, but the specifications and performance context reveal a dramatic shift in capabilities. The RX 7900M, built on the 5 nm process with RDNA 3.0, is a modern mobile powerhouse, while the Quadro GP100, using the 16 nm process and Pascal architecture, is an end-of-life workstation relic from 2016. This analysis will dissect their benchmark scores, architectural philosophies, and specification differences to determine which GPU holds up in a modern context.

Head-to-Head Benchmarks

The only direct comparison available is the Geekbench OpenCL test, and the result is decisively in favor of the AMD Radeon RX 7900M. The RX 7900M scores 129,499 points, while the Quadro GP100 trails with 87,445 points. This translates to a 48.1% advantage for the AMD part. This is not a marginal victory; it is a substantial generational leap. The RX 7900M’s score in this compute-focused test is 48.1% higher, indicating that its raw throughput for general-purpose GPU workloads is significantly superior.

This performance gap is further contextualized by their respective average benchmark scores. The RX 7900M has an average benchmark score of 97,487, which places it in the 94th percentile of all GPUs. The Quadro GP100, with an average score of 87,445, sits in the 93rd percentile. While both are high-performing parts, the RX 7900M’s average is notably higher. Looking at the nearest rivals for the RX 7900M, it is 4.3% behind the NVIDIA Quadro RTX 6000 (which averages 101,872) but 5.4% ahead of the AMD Radeon Instinct MI60 (which averages 92,466). This suggests that while the RX 7900M is strong, it is not the absolute top of its class.

The Quadro GP100’s performance context is different. Its nearest rivals include the AMD Radeon PRO W7600, which it beats by just 0.4% (87,108 vs. 87,445). It is also 2.1% ahead of the NVIDIA CMP 40HX (85,637), but 4.0% behind the NVIDIA RTX A4500 Mobile (91,134) and 4.6% behind the desktop RTX A4500 (91,671). The data suggests that the Quadro GP100’s performance is roughly on par with modern mid-range workstation GPUs, but it has been left behind by the high-end parts of today.

The Verdict

From a pure performance standpoint, the AMD Radeon RX 7900M is the clear winner. The benchmark results show it is 48.1% faster than the Quadro GP100 in OpenCL compute, and its average benchmark score is over 10,000 points higher. The RX 7900M also offers a more modern feature set, including support for DirectX 12 Ultimate (12_2) and Vulkan 1.4, which the Quadro GP100 cannot match. The Quadro GP100 is limited to DirectX 12 (12_1) and Vulkan 1.3, meaning it lacks the latest rendering features and optimizations.

The data indicates that the RX 7900M is the better choice for anyone needing maximum compute performance and modern API support. Its 94th percentile ranking versus the Quadro’s 93rd percentile, combined with the 48.1% head-to-head lead, is a decisive verdict. The Quadro GP100’s only potential advantage lies in its specific hardware characteristics, such as its massive 4096-bit memory bus, but this does not translate into a performance win in the available data. For any workload that relies on raw number-crunching, the RX 7900M is the superior product. The Quadro GP100, while still a competent performer, is a product of its time and is now outclassed by modern architecture.

Where Each One Wins

The AMD Radeon RX 7900M wins in nearly every measurable category. Its 48.1% lead in the Geekbench OpenCL test shows a clear advantage in compute-heavy tasks like scientific simulation, data processing, and rendering. The RX 7900M’s raw compute power is also evident in its specifications: it delivers 38.52 TFLOPS of FP32 performance versus the Quadro GP100’s 10.34 TFLOPS. This is a massive difference that would translate to faster processing in any FP32-heavy workload. The RX 7900M’s FP16 performance is also far superior at 77.05 TFLOPS compared to 20.69 TFLOPS on the Quadro.

The Quadro GP100 does have one notable hardware advantage: memory bandwidth. Its HBM2 memory provides 732.2 GB/s of bandwidth, which is higher than the RX 7900M’s 576.0 GB/s GDDR6. This could be a benefit in specific memory-bound workloads, such as certain types of data analytics or large dataset manipulation. However, this advantage is not reflected in the OpenCL benchmark, where the RX 7900M still wins decisively. The Quadro GP100 also has a smaller footprint in terms of power draw, but this is a physical attribute rather than a performance win. Furthermore, the RX 7900M is a mobile IGP, while the Quadro GP100 is a dual-slot desktop card, which changes the use case entirely.

Architecture Differences

The architectural chasm between these two GPUs is vast, stemming from a seven-year gap in development. The AMD Radeon RX 7900M utilizes the Navi 31 chip, built on the RDNA 3.0 architecture, with a process node of 5 nm at TSMC. This allows for a staggering 57,700 million transistors packed into a die size of 529 mm², yielding a transistor density of 109.1M per mm². In contrast, the NVIDIA Quadro GP100 uses the GP100 chip, based on the much older Pascal architecture, fabricated on a 16 nm process. It contains 15,300 million transistors on a larger 610 mm² die, resulting in a much lower transistor density of 25.1M per mm². This highlights the immense efficiency gains of the newer 5 nm process.

The compute architectures are also fundamentally different. The RX 7900M features 4608 shading units, 288 TMUs, and 192 ROPs. It also includes 72 dedicated ray tracing cores, a feature entirely absent from the Quadro GP100. The Quadro GP100, for its part, has 3584 shading units, 224 TMUs, and only 96 ROPs. Neither GPU has tensor cores. The RX 7900M’s architecture is designed for modern workloads, with support for DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Quadro GP100 is limited to DirectX 12 (12_1) and Vulkan 1.3. This means the RX 7900M can handle advanced features like hardware-accelerated ray tracing, which the Quadro cannot.

Specification Differences

The two GPUs differ significantly in nearly all core specifications. The most striking difference is in process node, with the RX 7900M at 5 nm and the Quadro GP100 at 16 nm. This underpins the massive difference in transistor count (57,700 million vs. 15,300 million). Clock speeds also favor the RX 7900M, with a base clock of 1825 MHz and boost of 2090 MHz, versus the Quadro GP100’s 1304 MHz base and 1443 MHz boost. Memory configurations are a mixed bag: the RX 7900M has 16 GB of GDDR6 on a 256-bit bus providing 576.0 GB/s, while the Quadro GP100 has 16 GB of HBM2 on a 4096-bit bus providing a higher 732.2 GB/s of bandwidth.

The compute output is where the RX 7900M dominates. Its pixel rate is 401.3 GPixel/s and texture rate is 601.9 GTexel/s, far exceeding the Quadro GP100’s 138.5 GPixel/s and 323.2 GTexel/s. FP32 performance is 38.52 TFLOPS for the RX 7900M, more than triple the Quadro GP100’s 10.34 TFLOPS. The power characteristics also differ: the RX 7900M is a 180 W IGP with no power connectors, while the Quadro GP100 is a 235 W dual-slot card requiring a 1x 8-pin connector and a 550 W suggested PSU. The bus interface is also newer on the RX 7900M (PCIe 4.0 x16) versus the Quadro GP100’s PCIe 3.0 x16. Finally, the RX 7900M is a mobile part with portable device-dependent outputs, while the Quadro GP100 is a fixed desktop card with 1x DVI and 4x DisplayPort 1.4a outputs.
