AMD Radeon RX 7900M vs NVIDIA TITAN X Pascal Comparison

The Verdict

The benchmark data is unambiguous: the AMD Radeon RX 7900M is the superior performer in every measured test, but the NVIDIA TITAN X Pascal is not without its niche. The RX 7900M dominates the head-to-head results, winning 2 out of 2 benchmarks. In Geekbench OpenCL, it scores 129,499 against the TITAN X Pascal’s 66,696, a decisive 94.2% advantage. In Geekbench Vulkan, the gap widens further: 158,760 versus 77,499, a 104.9% lead. The average benchmark score tells the same story—the RX 7900M sits at 97,487, while the TITAN X Pascal trails at 72,098.

However, the TITAN X Pascal still holds value for specific workloads, particularly those that rely on its legacy Pascal architecture and its 12 GB of GDDR5X memory on a 384-bit bus. The data suggests the RX 7900M is the clear choice for anyone prioritizing raw compute and modern API performance. The TITAN X Pascal, being end-of-life, is a product for collectors or those running software that specifically favors its older feature set. For most users, the RX 7900M is the definitive pick, with a percentile ranking of 94 against all GPUs, versus the TITAN X Pascal’s 91.

Where Each One Wins

The RX 7900M wins decisively in pure computational throughput. Its FP32 performance is 38.52 TFLOPS, more than triple the TITAN X Pascal’s 10.97 TFLOPS. This translates directly to its massive leads in OpenCL and Vulkan benchmarks. The RX 7900M also excels in memory bandwidth, delivering 576.0 GB/s on a 256-bit bus, compared to the TITAN X Pascal’s 480.4 GB/s on a wider 384-bit bus. The RX 7900M’s pixel rate of 401.3 GPixel/s and texture rate of 601.9 GTexel/s dwarf the TITAN X Pascal’s 147.0 GPixel/s and 342.9 GTexel/s, indicating far superior rasterization throughput.

The TITAN X Pascal does have one hardware advantage: memory capacity. It offers 12 GB of GDDR5X, whereas the RX 7900M offers 16 GB of GDDR6. Wait—that is not an advantage. The RX 7900M has 16 GB, which is 33% more memory. The TITAN X Pascal’s advantage is its power efficiency in reverse: it draws 250 W TDP, while the RX 7900M draws only 180 W. This means the RX 7900M achieves far higher performance at a lower power envelope. The TITAN X Pascal also has a physical form factor advantage for desktop users: it is a dual-slot card with standard display outputs (1x DVI, 1x HDMI 2.0, 3x DisplayPort 1.4a), whereas the RX 7900M is an integrated (IGP) mobile part with outputs described as "Portable Device Dependent."

Architecture Differences

The architectural gap between these two GPUs is generational. The AMD Radeon RX 7900M uses the Navi 31 chip on RDNA 3.0 architecture, built on a 5 nm TSMC process. It packs 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per mm². The NVIDIA TITAN X Pascal uses the GP102 chip on the Pascal architecture, built on a 16 nm TSMC process. It contains 11,800 million transistors on a 471 mm² die, with a density of just 25.1 million per mm². The RX 7900M’s process advantage is stark, enabling nearly five times the transistor density.

Core configuration diverges sharply. The RX 7900M has 4,608 shading units, 288 texture mapping units, 192 ROPs, and 72 ray tracing cores. The TITAN X Pascal has 3,584 shading units, 224 TMUs, and 96 ROPs, with no ray tracing cores and no tensor cores. The RX 7900M also supports DirectX 12 Ultimate (12_2), while the TITAN X Pascal is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, but the RX 7900M’s newer API support is a clear forward-looking advantage for modern game titles.

Clocks and memory technologies differ significantly. The RX 7900M runs at a base clock of 1825 MHz and boost of 2090 MHz, with memory at 2250 MHz (18 Gbps effective). The TITAN X Pascal runs at 1417 MHz base and 1531 MHz boost, with memory at 1251 MHz (10 Gbps effective). The RX 7900M uses GDDR6 memory, while the TITAN X Pascal uses GDDR5X. The RX 7900M’s FP16 throughput is 77.05 TFLOPS (2:1 ratio), whereas the TITAN X Pascal’s FP16 is a mere 171.5 GFLOPS (1:64 ratio)—a 450-fold difference in half-precision capability.

The RX 7900M is a PCIe 4.0 x16 part, while the TITAN X Pascal uses PCIe 3.0 x16. The RX 7900M is an integrated mobile GPU with no power connectors, whereas the TITAN X Pascal requires a 1x 6-pin and 1x 8-pin connector, with a suggested PSU of 600 W. Physically, the TITAN X Pascal measures 267 mm in length, 112 mm in height, and 40 mm in width, while the RX 7900M’s dimensions are not specified due to its IGP form factor.

FAQ

Q: What is the launch MSRP of the TITAN X Pascal?

A: The launch MSRP is 1,199 USD.

Q: Are these cards comparable in terms of production status?

A: No. The RX 7900M is listed as "Active" production, released in October 2023, while the TITAN X Pascal is "End-of-life," released in August 2016, with its successor being the GeForce 20 series.

Head-to-Head Benchmarks

The two available head-to-head benchmarks show a complete sweep by the AMD Radeon RX 7900M. In Geekbench OpenCL, the RX 7900M scores 129,499, while the TITAN X Pascal scores 66,696. The delta is 94.2%, meaning the RX 7900M nearly doubles the TITAN X Pascal’s performance in this compute-heavy OpenCL workload. This result is consistent with the massive difference in raw compute specifications: the RX 7900M’s 38.52 TFLOPS FP32 versus the TITAN X Pascal’s 10.97 TFLOPS, and its FP16 throughput of 77.05 TFLOPS versus a negligible 171.5 GFLOPS.

In Geekbench Vulkan, the RX 7900M scores 158,760, against the TITAN X Pascal’s 77,499. The delta here is 104.9%, meaning the RX 7900M is more than twice as fast. This is a striking result for a modern mobile GPU against a desktop flagship from the Pascal era. The Vulkan benchmark likely stresses the RX 7900M’s newer architecture features, including its 72 RT cores and DirectX 12 Ultimate support, which the TITAN X Pascal lacks entirely. The RX 7900M’s higher memory bandwidth (576.0 GB/s vs 480.4 GB/s) and faster clocks (1825 MHz base vs 1417 MHz base) also contribute to this performance gap.

Across both tests, the RX 7900M’s wins are not marginal—they are decisive, with deltas of 94.2% and 104.9%. The TITAN X Pascal’s nearest rivals in the overall database include the AMD Radeon Pro Vega 64 (delta -0.4%) and the AMD Radeon RX 6650M (delta 0.5%), indicating it sits near the performance of much newer mid-range parts. The RX 7900M, by contrast, is 0.4% below the AMD Radeon Pro VII and 5.4% above the AMD Radeon Instinct MI60, placing it in workstation-class territory. These numbers confirm that the RX 7900M is not just a generation ahead—it is in a entirely different performance tier.
