AMD Radeon RX 9050 vs NVIDIA GeForce RTX 5090 SE Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Radeon RX 9050 or the NVIDIA GeForce RTX 5090 SE. Both entries show an average benchmark score of zero, and the head-to-head benchmark array is empty. This means a direct numerical comparison of performance in synthetic workloads, gaming frame rates, or compute tasks cannot be derived from the recorded data at this time.

What can be compared directly is the theoretical throughput derived from the specification sheets. The RTX 5090 SE lists an FP32 compute rate of 66.94 TFLOPS, while the RX 9050 lists 10.65 TFLOPS. That is a 6.3x difference in raw single-precision floating-point throughput. Similarly, the texture fill rate on the NVIDIA card is 1,045.9 GTexel/s versus 166.4 GTexel/s on the AMD card, a 6.3x gap. The pixel rate tells the same story: 380.3 GPixel/s for the RTX 5090 SE versus 166.4 GPixel/s for the RX 9050, which is a 2.3x difference.

Memory bandwidth is another decisive separation point. The RTX 5090 SE uses a 384-bit bus with GDDR7 memory rated at 1.34 TB/s. The RX 9050 uses a 128-bit bus with GDDR6 memory rated at 288.0 GB/s. That is a 4.7x advantage for the NVIDIA part in raw memory throughput. The RTX 5090 SE also carries 24 GB of memory versus 8 GB on the RX 9050, a 3x capacity difference.

The shading resources are equally lopsided. The RTX 5090 SE has 14,080 shading units, 440 texture mapping units, and 160 ROPs. The RX 9050 has 1,024 shading units, 64 TMUs, and 64 ROPs. The NVIDIA card has 13.75x more shading units, 6.9x more TMUs, and 2.5x more ROPs. Ray tracing hardware shows a similar pattern: 110 RT cores on the RTX 5090 SE versus 16 on the RX 9050, a 6.9x difference. Tensor cores exist only on the NVIDIA card, with 440 of them; the AMD part lists none.

Clock speeds do not close the gap. The RX 9050 has a base clock of 1330 MHz and a boost of 2600 MHz, with a game clock of 1920 MHz. The RTX 5090 SE has a base of 1740 MHz and a boost of 2377 MHz, with no game clock listed. The AMD card's higher boost clock (2600 MHz versus 2377 MHz) is the only clock metric where it leads, but that 9.4% advantage is overwhelmed by the massive difference in execution resources.

Transistor counts and die sizes reinforce the scale difference. The RTX 5090 SE uses 92,200 million transistors on a 750 mm² die, while the RX 9050 uses 29,700 million transistors on a 199 mm² die. The NVIDIA chip is 3.1x larger in die area and packs 3.1x more transistors. The AMD part has a higher transistor density at 149.2 million per mm² versus 122.9 million per mm², reflecting the 4 nm process node versus the 5 nm node used for the NVIDIA chip.

The Verdict

Based on the recorded specification data, the RTX 5090 SE is in a different performance class entirely. Every measured throughput metric, from FP32 compute to texture rate to pixel rate to memory bandwidth, favors the NVIDIA card by a wide margin. The FP32 figure alone puts the RTX 5090 SE at 66.94 TFLOPS, which is 6.3x the RX 9050's 10.65 TFLOPS. Memory bandwidth at 1.34 TB/s versus 288.0 GB/s is a 4.7x advantage. The RTX 5090 SE has 24 GB of GDDR7 memory on a 384-bit bus; the RX 9050 has 8 GB of GDDR6 on a 128-bit bus.

The power draw reflects this performance gap. The RTX 5090 SE has a TDP of 500 W and a suggested PSU rating of 900 W, while the RX 9050 has a TDP of 92 W and a suggested PSU of 250 W. The NVIDIA card consumes 5.4x more power. Its power connector is a single 16-pin, while the AMD card uses a single 8-pin.

The launch MSRP of the RTX 5090 SE is 1,499 USD. The RX 9050 has no launch MSRP listed in the database.

For workloads that depend on raw compute throughput, large memory capacity, or high memory bandwidth, the RTX 5090 SE is the clear choice based on the data. For workloads that prioritize low power draw, the RX 9050 holds the advantage, drawing less than one-fifth the power of the NVIDIA card.

Where Each One Wins

The RTX 5090 SE wins decisively in every performance-oriented category recorded in the database. It leads in FP32 compute (66.94 TFLOPS versus 10.65 TFLOPS), texture rate (1,045.9 GTexel/s versus 166.4 GTexel/s), pixel rate (380.3 GPixel/s versus 166.4 GPixel/s), memory capacity (24 GB versus 8 GB), memory bandwidth (1.34 TB/s versus 288.0 GB/s), shading units (14,080 versus 1,024), TMUs (440 versus 64), ROPs (160 versus 64), and RT cores (110 versus 16). It also has 440 tensor cores, a feature the RX 9050 lacks entirely.

The RX 9050 wins in power efficiency, measured by TDP and suggested PSU requirements. Its 92 W TDP is dramatically lower than the 500 W TDP of the RTX 5090 SE, and its 250 W suggested PSU is far below the 900 W requirement of the NVIDIA card. The RX 9050 also has a higher boost clock (2600 MHz versus 2377 MHz) and a smaller die (199 mm² versus 750 mm²), which means it uses far less silicon area. The AMD card's transistor density of 149.2 million per mm² exceeds the NVIDIA card's 122.9 million per mm², indicating a more compact logic design.

Both cards support the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use PCIe 5.0 x16 interfaces and are dual-slot designs.

Architecture Differences

The two cards come from different architectural generations and design philosophies. The RX 9050 uses the RDNA 4.0 architecture on the Navi 44 chip, part of the Navi IV (RX 9000) generation. The RTX 5090 SE uses the Blackwell 2.0 architecture on the GB202 chip, part of the GeForce 50-series generation. The AMD card is built on a 4 nm TSMC process, while the NVIDIA card uses a 5 nm TSMC process.

The transistor budgets differ enormously. The GB202 chip contains 92,200 million transistors across a 750 mm² die, giving a density of 122.9 million per mm². The Navi 44 chip contains 29,700 million transistors on a 199 mm² die, for a density of 149.2 million per mm². The AMD chip is denser, but the NVIDIA chip is 3.1x larger in both area and transistor count.

Compute resource allocation shows the fundamental architectural split. The RTX 5090 SE uses 14,080 shading units, 440 TMUs, and 160 ROPs, alongside 110 RT cores and 440 tensor cores. The RX 9050 uses 1,024 shading units, 64 TMUs, and 64 ROPs, with 16 RT cores and no tensor cores. The NVIDIA architecture dedicates substantial silicon to tensor operations, which are absent from the AMD part.

Memory architecture differs in type and width. The RTX 5090 SE uses GDDR7 on a 384-bit bus, achieving 1.34 TB/s of bandwidth. The RX 9050 uses GDDR6 on a 128-bit bus, achieving 288.0 GB/s. The NVIDIA memory clock runs at 1750 MHz with 28 Gbps effective, while the AMD memory runs at 2250 MHz with 18 Gbps effective. Despite the lower memory clock, the wider bus gives the NVIDIA card a massive bandwidth advantage.

Clock behavior also differs. The RX 9050 lists a game clock of 1920 MHz, a feature the RTX 5090 SE does not report. The AMD card boosts to 2600 MHz, higher than the NVIDIA card's 2377 MHz, but the NVIDIA base clock is 1740 MHz versus 1330 MHz for the AMD part.
