AMD Ryzen Z2 A GPU vs NVIDIA GeForce RTX 5090 SE Comparison

Head-to-Head Benchmarks

The recorded database contains no direct benchmark scores for either the AMD Ryzen Z2 A GPU or the NVIDIA GeForce RTX 5090 SE, and no head-to-head benchmark results are available. Both parts have an identical percentile rank of 50 against all GPUs in the database, meaning neither unit has a measured performance advantage over the other in the current dataset. The average benchmark score for both is zero, so no direct numerical comparison of gaming or compute performance can be drawn from the recorded measurements. What can be compared are the architectural specifications, raw throughput figures, and feature sets, which show a massive gap in theoretical capability between the two designs.

On raw compute throughput, the NVIDIA part lists 66.94 TFLOPS of FP32 performance, while the AMD part lists 1.638 TFLOPS. That places the RTX 5090 SE at roughly 40.9 times the FP32 figure of the Ryzen Z2 A GPU. In FP16, the NVIDIA card also lists 66.94 TFLOPS with a 1:1 ratio, while the AMD chip lists 3.277 TFLOPS with a 2:1 ratio. Pixel throughput shows a similar gulf: the RTX 5090 SE delivers 380.3 GPixel/s versus 25.60 GPixel/s for the AMD part, a factor of about 14.9. Texture rate compares at 1,045.9 GTexel/s versus 51.20 GTexel/s, roughly 20.4 times higher on the NVIDIA side.

Memory bandwidth is another decisive split. The RTX 5090 SE has 1.34 TB/s of bandwidth, while the Ryzen Z2 A GPU has 102.4 GB/s. That is a difference of roughly 13.1 times in favor of the NVIDIA card. The memory capacity difference is smaller but still notable: 24 GB on the NVIDIA card versus 16 GB on the AMD part. Clock speeds also favor the NVIDIA card. The RTX 5090 SE has a base clock of 1740 MHz and a boost clock of 2377 MHz, while the AMD chip has a base of 1000 MHz and a boost of 1600 MHz. Memory clocks differ as well, with the NVIDIA card running at 1750 MHz (28 Gbps effective) and the AMD part at 800 MHz (6.4 Gbps effective).

Architecture Differences

The two GPUs come from entirely different architectural lineages. The AMD Ryzen Z2 A GPU uses the Van Gogh chip built on RDNA 2.0, while the NVIDIA GeForce RTX 5090 SE uses the GB202 chip built on Blackwell 2.0. The process nodes differ: the AMD part is fabricated on a 7 nm process at TSMC, and the NVIDIA part is fabricated on a 5 nm process, also at TSMC. The transistor counts are dramatically different. The AMD chip contains 2,400 million transistors on a 163 mm² die, giving a transistor density of 14.7 million transistors per square millimeter. The NVIDIA chip contains 92,200 million transistors on a 750 mm² die, giving a density of 122.9 million per square millimeter. That is a density difference of roughly 8.4 times, and a total transistor count difference of about 38.4 times.

The core configurations reflect their different purposes. The AMD chip has 512 shading units, 32 texture mapping units, 16 render output units, and 8 ray tracing cores. The NVIDIA chip has 14,080 shading units, 440 TMUs, 160 ROPs, 110 ray tracing cores, and 440 tensor cores. The AMD part has no tensor cores listed, while the NVIDIA part includes them. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The memory types differ fundamentally: the AMD chip uses LPDDR5 on a 128-bit bus, while the NVIDIA card uses GDDR7 on a 384-bit bus.

Power and physical specifications diverge sharply. The AMD chip has a TDP of 15 W, while the NVIDIA card has a TDP of 500 W. The NVIDIA card is dual-slot, uses a single 16-pin power connector, and recommends a 900 W power supply. The AMD chip lists no slot width, no power connectors, and no suggested PSU. The NVIDIA card uses a PCIe 5.0 x16 bus interface, while the AMD chip lists no bus interface. Display outputs differ as well: the AMD chip has a single USB Type-C output, while the NVIDIA card has 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs. The NVIDIA card has physical dimensions of 267 mm in length, 111 mm in height, and 40 mm in width. The AMD chip lists no physical dimensions.

Where Each One Wins

The data shows that the NVIDIA GeForce RTX 5090 SE wins decisively in every measured specification category. It delivers higher FP32 and FP16 throughput, higher pixel fill rate, higher texture fill rate, more memory capacity, faster memory type, wider memory bus, higher bandwidth, more shading units, more TMUs, more ROPs, more ray tracing cores, and the only tensor cores between the two. It also has higher base and boost clocks, higher memory clocks, and a newer architecture on a smaller process node.

The AMD Ryzen Z2 A GPU wins in power efficiency on paper. Its 15 W TDP is dramatically lower than the 500 W TDP of the NVIDIA card, representing a 33.3 times smaller power envelope. The AMD chip also has a smaller die size at 163 mm² versus 750 mm², which is about 4.6 times smaller. For systems where power draw and physical footprint are the primary constraints, the AMD part presents a far lighter thermal and electrical load. The AMD chip also uses a single USB Type-C display output, which may simplify cabling in compact designs.

The NVIDIA card wins in every performance-oriented category without exception. Its FP32 throughput is roughly 40.9 times higher, its texture rate is about 20.4 times higher, its pixel rate is about 14.9 times higher, and its memory bandwidth is about 13.1 times higher. The RTX 5090 SE also has 14,080 shading units versus 512, 440 TMUs versus 32, 160 ROPs versus 16, and 110 ray tracing cores versus 8. The tensor core count of 440 on the NVIDIA side has no counterpart on the AMD side. The NVIDIA card also has a larger memory pool of 24 GB versus 16 GB, and a wider 384-bit bus versus 128-bit.
