AMD Radeon RX 6450M vs NVIDIA GeForce RTX 5080 SUPER Comparison

AMD Radeon RX 6450M and NVIDIA GeForce RTX 5080 SUPER occupy opposite ends of the mobile and desktop graphics spectrum. The RX 6450M is a 50 W integrated-class part built for thin-and-light portables, while the RTX 5080 SUPER is a 415 W dual-slot desktop flagship. Direct benchmark comparisons between the two are not available in the database, so the analysis below relies on architectural specifications, memory configurations, and the recorded performance of the RTX 5080 SUPER.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two products. The only recorded benchmark score belongs to the NVIDIA GeForce RTX 5080 SUPER, which achieved 3075 points in the 3DMark Steel Nomad DX12 test. This score places the RTX 5080 SUPER at the 19th percentile among all GPUs in the database, meaning roughly 81 percent of recorded GPUs perform better in that specific test.

Looking at the nearest rivals for the RTX 5080 SUPER, the data shows the NVIDIA Quadro P1000 scored 3163 points, which is 2.8 percent higher. The Intel Arc Pro B60 scored 3182 points, 3.4 percent higher. On the lower side, the NVIDIA GeForce 820A scored 2983 points, 3.1 percent lower, and the NVIDIA GeForce GTX 860M scored 2967 points, 3.6 percent lower. The RTX 5080 SUPER sits between these two clusters, trailing the Quadro P1000 and Arc Pro B60 while leading the 820A and GTX 860M.

These rival scores are all far below what the RTX 5080 SUPER's specifications would suggest, and the 19th percentile ranking indicates the recorded benchmark may not represent the card's full capability. The AMD Radeon RX 6450M has no benchmark scores or nearest rival entries in the database, so no direct numerical comparison can be made between the two products.

Where Each One Wins

Without shared benchmark data, the wins must be inferred from the hardware specifications listed in the database. The NVIDIA GeForce RTX 5080 SUPER holds decisive advantages in nearly every measurable category. Its FP32 performance is 56.28 TFLOPS compared to 3.779 TFLOPS for the RX 6450M, a difference of roughly 14.9 times. The RTX 5080 SUPER also delivers 879.3 GTexel/s of texture rate versus 118.1 GTexel/s, and 293.1 GPixel/s of pixel rate versus 78.72 GPixel/s.

Memory capacity favors the RTX 5080 SUPER with 24 GB of GDDR7 on a 256-bit bus, providing 1.02 TB/s of bandwidth. The RX 6450M offers 4 GB of GDDR6 on a 64-bit bus with 128.0 GB/s of bandwidth. The RTX 5080 SUPER has 10752 shading units, 336 texture mapping units, 112 ROPs, 84 ray tracing cores, and 336 tensor cores. The RX 6450M has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores, with no tensor cores listed.

The RTX 5080 SUPER also wins on process technology, using a 5 nm node with 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6 million per mm². The RX 6450M uses a 6 nm node with 5,400 million transistors on a 107 mm² die, resulting in a density of 50.5 million per mm².

The RX 6450M wins only in power efficiency and form factor. Its 50 W TDP is dramatically lower than the 415 W TDP of the RTX 5080 SUPER. The RX 6450M is an integrated graphics processor with no power connectors and a portable device dependent display output, while the RTX 5080 SUPER requires a single 16-pin power connector and occupies a dual-slot design measuring 304 mm in length, 137 mm in height, and 40 mm in width.

The Verdict

The database shows two products built for entirely different use cases. The AMD Radeon RX 6450M is a low-power mobile solution with a 50 W TDP, integrated form factor, and 4 GB of memory. It targets portable devices where power draw and physical space are the primary constraints. Its 3.779 TFLOPS of FP32 performance and 128.0 GB/s of memory bandwidth are modest figures, suitable for light graphics workloads.

The NVIDIA GeForce RTX 5080 SUPER is a desktop flagship with a 415 W TDP, requiring a dual-slot cooler and a 16-pin power connector. Its 24 GB of GDDR7 memory, 1.02 TB/s bandwidth, and 56.28 TFLOPS of FP32 compute place it in an entirely different performance class. The 84 ray tracing cores and 336 tensor cores provide dedicated hardware for ray tracing and AI-accelerated workloads that the RX 6450M cannot match, as the latter has only 12 ray tracing cores and no tensor cores.

Users needing maximum graphics throughput in a desktop workstation or gaming rig would pick the RTX 5080 SUPER based on its specifications. Users prioritizing low power consumption, compact integration, and portability would select the RX 6450M. The data does not support a direct performance comparison, but the specification gap is so large that the choice is dictated by the target platform rather than by benchmark results.
