NVIDIA GeForce RTX 5090 SE vs NVIDIA RTX A1000 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the NVIDIA GeForce RTX 5090 SE and the NVIDIA RTX A1000. The RTX 5090 SE has no benchmark scores listed in the database, while the RTX A1000 has three recorded results. This absence of overlapping test data means the performance relationship must be inferred from the architectural and specification differences rather than from direct measurements.

The RTX A1000's benchmark results place it in the 79th percentile of all GPUs tracked by the database. Its average benchmark score of 34,207 is nearly identical to its nearest rivals. The NVIDIA RTX A2000 12 GB scores 34,154, a delta of 0.2% behind the A1000. The AMD Radeon RX 560 XT also scores 34,133, another 0.2% delta. The NVIDIA TITAN V scores 34,355, which is 0.4% ahead of the A1000, while the AMD Radeon RX 480 scores 33,997, a 0.6% deficit. These narrow margins indicate the A1000 sits in a tightly contested performance cluster.

In individual tests, the RTX A1000 delivers a 3DMark Steel Nomad DX12 score of 969. Its Geekbench OpenCL score reaches 52,078, and its Geekbench Vulkan score is 49,574. These figures establish a baseline for the A1000's compute capabilities, but without corresponding RTX 5090 SE scores, no direct percentage advantage can be calculated.

The RTX 5090 SE has an average benchmark score of 0 and a 50th percentile placement, reflecting the absence of recorded test data rather than actual performance. Its FP32 compute rating of 66.94 TFLOPS compared to the A1000's 6.737 TFLOPS suggests a substantial theoretical advantage, approximately an order of magnitude in raw shading throughput. The pixel rate of 380.3 GPixel/s versus 46.78 GPixel/s and texture rate of 1,045.9 GTexel/s versus 105.3 GTexel/s point to similarly large gaps in rasterization throughput.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing processes. The RTX 5090 SE uses the GB202 chip built on the Blackwell 2.0 architecture, fabricated by TSMC on a 5 nm process. The RTX A1000 uses the GA107 chip based on the Ampere architecture, fabricated by Samsung on an 8 nm process. This process difference contributes to the transistor counts: the RTX 5090 SE packs 92,200 million transistors on a 750 mm² die, while the RTX A1000 contains 8,700 million transistors on a 200 mm² die. The resulting transistor density is 122.9 million per mm² for the RTX 5090 SE versus 43.5 million per mm² for the RTX A1000.

The RTX 5090 SE belongs to the GeForce 50-series generation and the Blackwell 2.0 architecture, while the RTX A1000 belongs to the Workstation Ampere (Ax000) generation. The RTX 5090 SE's predecessor is the GeForce 40 series and its successor is the GeForce 60 series. The RTX A1000's predecessor is the Quadro Turing line and its successor is the Workstation Ada generation.

Clock speeds differ substantially. The RTX 5090 SE has a base clock of 1740 MHz and a boost clock of 2377 MHz. The RTX A1000 runs at a 727 MHz base clock and a 1462 MHz boost clock. Memory clocks also diverge: the RTX 5090 SE operates at 1750 MHz with 28 Gbps effective speed, while the RTX A1000 runs at 1500 MHz with 12 Gbps effective speed.

The compute resources scale dramatically between the two. The RTX 5090 SE contains 14,080 shading units, 440 texture mapping units, 160 raster operations pipelines, 110 ray tracing cores, and 440 tensor cores. The RTX A1000 has 2,304 shading units, 72 TMUs, 32 ROPs, 18 RT cores, and 72 tensor cores. These ratios show the RTX 5090 SE carrying roughly six times the shading units, six times the TMUs, and five times the ROPs of the A1000.

Both GPUs support the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5090 SE's FP16 throughput matches its FP32 at 66.94 TFLOPS with a 1:1 ratio, and the RTX A1000 likewise matches FP16 to FP32 at 6.737 TFLOPS.

Where Each One Wins

The RTX 5090 SE wins in every measured architectural metric. Its FP32 compute of 66.94 TFLOPS is approximately 9.9 times the A1000's 6.737 TFLOPS. The pixel rate advantage is 8.1 times (380.3 GPixel/s versus 46.78 GPixel/s), and the texture rate advantage is 9.9 times (1,045.9 GTexel/s versus 105.3 GTexel/s). Memory bandwidth is 7.0 times higher at 1.34 TB/s versus 192.0 GB/s. The RTX 5090 SE also carries 6.1 times the shading units, 6.1 times the TMUs, 5.0 times the ROPs, 6.1 times the RT cores, and 6.1 times the tensor cores compared to the A1000.

The RTX A1000 wins in efficiency-oriented categories. Its 50 W TDP is one-tenth of the RTX 5090 SE's 500 W rating. The A1000 requires no external power connectors, while the RTX 5090 SE needs a 16-pin connector and a 900 W suggested PSU. The A1000's single-slot form factor at 163 mm length is considerably more compact than the dual-slot, 267 mm RTX 5090 SE. The A1000 also provides four display outputs versus the RTX 5090 SE's four total outputs, though with different connector types.

In terms of the database's recorded benchmark data, the RTX A1000 has an established average score of 34,207 and a 79th percentile placement. The RTX 5090 SE has no recorded scores, so its percentile of 50 reflects missing data rather than measured performance. The A1000's nearest rivals all sit within 0.6% of its average score, indicating the A1000 holds a stable position in its performance tier.

The Verdict

The data indicates a complete performance class separation between these two GPUs. The RTX 5090 SE is designed for maximum compute throughput, with 66.94 TFLOPS FP32, 24 GB of GDDR7 memory, and 1.34 TB/s bandwidth. The RTX A1000 is designed for low-power workstation duties, with 6.737 TFLOPS FP32, 8 GB of GDDR6 memory, and 192.0 GB/s bandwidth.

For workloads that demand raw shading, ray tracing, or tensor performance, the RTX 5090 SE's specifications dominate in every category. Its 110 RT cores and 440 tensor cores versus the A1000's 18 and 72 respectively indicate a substantial advantage for ray-traced rendering and AI-accelerated tasks. The RTX 5090 SE's 24 GB memory capacity and 384-bit bus support large datasets that the A1000's 8 GB and 128-bit bus cannot accommodate.

For environments with strict power or space constraints, the RTX A1000 holds clear advantages. Its 50 W TDP, no power connectors, and single-slot 163 mm length make it suitable for systems where the RTX 5090 SE's 500 W TDP, 16-pin connector, and dual-slot 267 mm length would be prohibitive. The A1000's PCIe 4.0 x8 interface also consumes fewer lanes than the RTX 5090 SE's PCIe 5.0 x16.

The RTX A1000's benchmark presence in the database, with scores in 3DMark Steel Nomad DX12, Geekbench OpenCL, and Geekbench Vulkan, provides measurable evidence of its performance tier. The RTX 5090 SE lacks recorded benchmark data, so its performance must be inferred from the specification sheet. The RTX 5090 SE's launch MSRP is 1,499 USD, while the A1000 has no listed launch MSRP.

The choice between these GPUs follows the recorded specifications. The RTX 5090 SE targets high-end rendering and compute workloads where its 9.9x FP32 advantage and 7.0x memory bandwidth advantage translate directly into reduced processing times. The RTX A1000 targets compact, low-power workstations where its 50 W TDP and single-slot design enable deployment in systems that cannot accommodate the RTX 5090 SE's power and physical requirements. The RTX 5090 SE's 50th percentile placement versus the A1000's 79th percentile reflects the database's current measurement coverage, not an indication of relative capability.
