AMD Ryzen Z1 GPU vs NVIDIA GeForce RTX 5090 SE Comparison

Where Each One Wins

The AMD Ryzen Z1 GPU and the NVIDIA GeForce RTX 5090 SE occupy completely different positions in the database. The Ryzen Z1 GPU is a console-class integrated graphics solution built on the Phoenix chip, while the RTX 5090 SE is a flagship discrete desktop GPU from the GeForce 50-series. The recorded benchmark data shows no head-to-head wins for either part, but the architectural specifications alone establish a clear separation of purpose.

The Ryzen Z1 GPU wins in the domain of power efficiency and compact integration. Its 30 W TDP is a fraction of the RTX 5090 SE's 500 W TDP. The Z1 GPU uses no power connectors, while the RTX 5090 SE requires a single 16-pin connector and a suggested 900 W power supply. The Z1 GPU measures 280 mm in length, 111 mm in height, and 21 mm in width, compared to the RTX 5090 SE's 267 mm length, 111 mm height, and 40 mm width. The Z1 GPU is thinner, making it suitable for low-profile implementations.

The RTX 5090 SE wins decisively in raw compute capability. Its shading unit count of 14,080 dwarfs the Z1 GPU's 256 shading units. The RTX 5090 SE delivers 66.94 TFLOPS of FP32 compute, while the Z1 GPU manages 2.560 TFLOPS. The RTX 5090 SE also leads in memory bandwidth at 1.34 TB/s versus 51.20 GB/s for the Z1 GPU. The RTX 5090 SE's 24 GB of GDDR7 memory on a 384-bit bus far exceeds the Z1 GPU's 16 GB of LPDDR5 on a 64-bit bus.

The use-case split is straightforward. The Z1 GPU targets embedded or handheld-class workloads where power draw and physical footprint are primary constraints. The RTX 5090 SE targets desktop gaming and compute workloads where maximum throughput is the goal. The database shows the Z1 GPU with no display outputs, indicating it is not designed as a standalone graphics solution, whereas the RTX 5090 SE offers 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs.

Architecture Differences

The two GPUs belong to different architectural generations and process nodes. The AMD Ryzen Z1 GPU uses the Phoenix chip with RDNA 3.0 architecture on a 4 nm TSMC process. The NVIDIA GeForce RTX 5090 SE uses the GB202 chip with Blackwell 2.0 architecture on a 5 nm TSMC process. The Z1 GPU integrates 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6 million per square millimeter. The RTX 5090 SE integrates 92,200 million transistors on a 750 mm² die, yielding a transistor density of 122.9 million per square millimeter.

The memory subsystems differ fundamentally. The Z1 GPU uses 16 GB of LPDDR5 at 800 MHz with 6.4 Gbps effective speed, connected via a 64-bit bus. The RTX 5090 SE uses 24 GB of GDDR7 at 1750 MHz with 28 Gbps effective speed, connected via a 384-bit bus. The bandwidth gap is enormous: 1.34 TB/s versus 51.20 GB/s.

Compute resources diverge sharply. The Z1 GPU has 256 shading units, 16 texture mapping units, 8 ROPs, and 4 ray tracing cores. The RTX 5090 SE has 14,080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores. The Z1 GPU has no tensor cores listed, while the RTX 5090 SE includes a full tensor core array. The Z1 GPU's FP16 throughput is 5.120 TFLOPS at a 2:1 ratio, while the RTX 5090 SE delivers 66.94 TFLOPS at a 1:1 ratio.

The physical and interface specifications also differ. The RTX 5090 SE uses a PCIe 5.0 x16 bus interface, while the Z1 GPU has no bus interface listed. The RTX 5090 SE is dual-slot and uses a 1x 16-pin power connector. The Z1 GPU uses no power connectors. The production status for both is Active, but the release dates differ: the Z1 GPU launched on 2023-09-17, and the RTX 5090 SE launched on 2025-12-31.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results between the AMD Ryzen Z1 GPU and the NVIDIA GeForce RTX 5090 SE. Both parts have zero benchmark scores and zero wins in the comparison table. The percentile ranking for each against all GPUs is identical at 50, indicating that the database has not yet generated comparative performance data for these two products.

In the absence of direct measurements, the specification data provides the only basis for comparison. The RTX 5090 SE's FP32 throughput of 66.94 TFLOPS is approximately 26 times the Z1 GPU's 2.560 TFLOPS. The RTX 5090 SE's texture rate of 1,045.9 GTexel/s is roughly 26 times the Z1 GPU's 40.00 GTexel/s. The RTX 5090 SE's pixel rate of 380.3 GPixel/s is about 19 times the Z1 GPU's 20.00 GPixel/s.

Memory bandwidth shows the largest relative gap. The RTX 5090 SE's 1.34 TB/s bandwidth is approximately 26 times the Z1 GPU's 51.20 GB/s. The RTX 5090 SE's memory bus width of 384 bits is six times the Z1 GPU's 64-bit bus. The RTX 5090 SE's 24 GB frame buffer is 1.5 times the Z1 GPU's 16 GB capacity.

The RTX 5090 SE also leads in ray tracing resources with 110 RT cores versus 4 for the Z1 GPU. The RTX 5090 SE's tensor core count of 440 provides dedicated AI acceleration hardware that the Z1 GPU lacks entirely.

Clock speeds are closer than other metrics. The Z1 GPU has a base clock of 1500 MHz and a boost clock of 2500 MHz. The RTX 5090 SE has a base clock of 1740 MHz and a boost clock of 2377 MHz. The Z1 GPU actually has a higher boost clock, but its far smaller execution resources mean the clock advantage does not translate into competitive throughput.

The Verdict

The data indicates that these two GPUs should not be compared as direct competitors. The AMD Ryzen Z1 GPU is a low-power integrated solution with a 30 W TDP, no display outputs, and no power connectors. It uses 16 GB of LPDDR5 memory and delivers 2.560 TFLOPS of FP32 compute. The NVIDIA GeForce RTX 5090 SE is a high-end discrete desktop GPU with a 500 W TDP, a PCIe 5.0 x16 interface, and a full suite of display outputs. It delivers 66.94 TFLOPS of FP32 compute and 24 GB of GDDR7 memory.

For workloads constrained by power draw, physical size, or thermal limits, the Z1 GPU is the only viable option in this comparison. Its 30 W TDP is 16.7 times lower than the RTX 5090 SE's 500 W TDP. Its 21 mm width versus 40 mm width allows for slimmer chassis designs. Its lack of external power connectors simplifies system integration.

For workloads requiring maximum graphics throughput, memory bandwidth, or ray tracing performance, the RTX 5090 SE is the clear choice. Its FP32 compute is 26 times higher, its memory bandwidth is 26 times higher, and its RT core count is 27.5 times higher. The RTX 5090 SE also supports tensor cores for AI workloads, which the Z1 GPU does not provide.

The RTX 5090 SE's launch MSRP is 1,499 USD, while the Z1 GPU's launch MSRP is 599 USD. Both parts remain in Active production status. The RTX 5090 SE has a predecessor in the GeForce 40 series and a successor in the GeForce 60 series, indicating an established product line. The Z1 GPU has no listed predecessor or successor.

Users selecting between these parts should base their decision on the platform requirements. The Z1 GPU suits integrated, low-power systems. The RTX 5090 SE suits high-performance desktop workstations and gaming rigs. The database shows no overlap in their intended use cases.
