Architecture Differences

The Radeon 8050S uses AMD's RDNA 3.5 architecture on a 4 nm TSMC process, built around the Strix Halo chip with a die size of 308 mm². The RTX 5090 Mobile employs NVIDIA's Blackwell 2.0 architecture on a 5 nm TSMC node, using the GB203 chip with a larger 378 mm² die and 45,600 million transistors. The AMD part integrates graphics directly into the processor package (IGP), while the NVIDIA part is also an integrated solution but with a discrete-class memory subsystem.

The shader configuration differs dramatically. The Radeon 8050S has 2,048 shading units, 128 texture mapping units, and 64 raster output pipelines. The RTX 5090 Mobile more than quintuples shading units to 10,496, with 328 TMUs and 112 ROPs. Ray tracing hardware also diverges: AMD packs 32 RT cores, NVIDIA provides 82. The NVIDIA GPU includes 328 tensor cores, while the AMD part has no tensor core count recorded.

The memory architecture is the most fundamental split. The Radeon 8050S relies entirely on system-shared memory, with capacity, type, and bus width all listed as system shared, and bandwidth dependent on the host platform. The RTX 5090 Mobile brings dedicated 24 GB GDDR7 memory on a 256-bit interface, yielding 896.0 GB/s of bandwidth. This dedicated versus shared memory setup explains much of the performance delta in memory-heavy workloads.

Clock behavior also differs. The Radeon 8050S runs at a 1295 MHz base and boosts to 2800 MHz, while the RTX 5090 Mobile operates at a 990 MHz base and 1515 MHz boost. The AMD part's higher boost clock partially compensates for its lower shader count, but the NVIDIA chip's memory clock is rated at 1750 MHz with 28 Gbps effective speed.

Head-to-Head Benchmarks

The database records two direct comparisons between these GPUs, both in Geekbench workloads, and NVIDIA wins both decisively.

In Geekbench OpenCL, the RTX 5090 Mobile scores 201,834 against the Radeon 8050S's 65,818. That is a 67.4% advantage for NVIDIA. This result aligns with the massive shader core difference: the RTX 5090 Mobile has 10,496 shading units versus 2,048 on the AMD part, and the NVIDIA GPU's dedicated GDDR7 memory with 896.0 GB/s bandwidth avoids the bottleneck of system-shared memory.

Geekbench Vulkan shows an even larger gap. The RTX 5090 Mobile scores 198,405, while the Radeon 8050S manages 58,398. The delta is 70.6% in NVIDIA's favor. Vulkan workloads often scale strongly with raw compute throughput, and the RTX 5090 Mobile's 31.80 TFLOPS FP32 performance dwarfs the Radeon 8050S's 11.47 TFLOPS, a 2.77x difference in theoretical compute.

The Radeon 8050S does counter in certain metrics. Its pixel rate is 179.2 GPixel/s versus 169.7 GPixel/s for the RTX 5090 Mobile, a 5.6% win for AMD despite having fewer ROPs (64 vs 112). The AMD part also has a higher boost clock (2800 MHz vs 1515 MHz), which helps its texture rate of 358.4 GTexel/s, though NVIDIA's 496.9 GTexel/s remains 27.9% higher.

However, the overall benchmark picture favors NVIDIA. The RTX 5090 Mobile also holds additional PassMark scores in the database: 30,034 in G3D, 13,401 in GPU compute, 1,057 in G2D, and DirectX 9/10/11/12 scores of 324, 183, 269, and 138 respectively. The Radeon 8050S has no recorded PassMark results, so cross-validation is limited to the two Geekbench tests.

The Verdict

The data points to a clear split in workload suitability. The RTX 5090 Mobile wins every recorded head-to-head benchmark against the Radeon 8050S, with margins of 67.4% in OpenCL and 70.6% in Vulkan. Its 31.80 TFLOPS FP32 compute, 82 RT cores, 328 tensor cores, and 24 GB of GDDR7 memory with 896.0 GB/s bandwidth make it the superior choice for compute-heavy, ray-traced, or AI-accelerated workloads. The 95 W TDP reflects the higher power envelope required to feed those resources.

The Radeon 8050S is not without merit. Its 55 W TDP is 42.1% lower than NVIDIA's, making it the more power-efficient option on paper. It also has a higher boost clock (2800 MHz) and a superior pixel rate (179.2 GPixel/s versus 169.7 GPixel/s), which suggests strength in certain rasterization-bound scenarios. Its average benchmark score of 62,108 outperforms the RTX 5090 Mobile's 45,152, though this average includes NVIDIA's weaker PassMark results that are not directly comparable.

For users prioritizing raw compute, dedicated memory bandwidth, and ray tracing capability, the RTX 5090 Mobile is the clear pick from the recorded data. For those needing lower power draw and integrated simplicity, especially in thin-and-light designs where system-shared memory suffices, the Radeon 8050S offers a credible alternative, albeit one that trails substantially in the two direct comparisons available. The percentile rankings reflect this nuance: the Radeon 8050S sits at the 89th percentile among all GPUs, while the RTX 5090 Mobile is at the 84th, meaning the AMD part compares more favorably against the broader GPU population despite losing the head-to-head.
