NVIDIA GeForce RTX 5090 Mobile vs NVIDIA RTX A1000 Comparison

The head-to-head data recorded in the database leaves little ambiguity: the NVIDIA GeForce RTX 5090 Mobile wins every shared benchmark against the NVIDIA RTX A1000, and by margins that place the two products in entirely different performance classes. The RTX 5090 Mobile leads by triple digits in all three common tests, including a 505.9% advantage in 3DMark Steel Nomad (DirectX 12). That said, the RTX A1000 is not a failed competitor but a differently shaped product, a single-slot workstation card with a modest 50 W TDP and a compact physical footprint, while the RTX 5090 Mobile is an integrated mobile flagship drawing 95 W. The comparison is therefore less about which card wins on paper and more about which form factor and workload profile fits the buyer.

Where Each One Wins

The GeForce RTX 5090 Mobile wins everywhere performance is measured. It sweeps the shared benchmark suite three wins to zero, dominates in ray tracing throughput thanks to 82 RT cores against 18, and nearly matches the raw compute of upper-tier desktop-class parts: its average benchmark score of 45152 sits in the 84th percentile of all GPUs in the database, within striking distance of cards like the NVIDIA GeForce RTX 4070 Ti (44795 average, a 0.8% gap in the 5090 Mobile's favor) and the NVIDIA RTX 5880 Ada Generation (45972, 1.8% ahead of it). For gaming, heavy GPU compute, Vulkan and OpenCL workloads, and content creation, the recorded data shows it is the clear pick.

The RTX A1000 wins on physical and platform efficiency, not speed. It is a single-slot card with recorded dimensions of 163 mm length and 69 mm height, requires no auxiliary power connectors, and carries a suggested PSU of just 250 W. Its 50 W TDP is roughly half the 95 W draw of the 5090 Mobile, and its average score of 34207 still lands in the 79th percentile of all GPUs, ahead of peers such as the NVIDIA RTX A2000 12 GB (34154, 0.2% behind it) and the NVIDIA TITAN V (34355, 0.4% ahead of it). For slim workstation builds where slot count, card length, and power envelope are hard constraints, the A1000 is the only one of the two that fits the description at all, since the 5090 Mobile is an IGP-class mobile part integrated into a portable device.

FAQ

Q: How large is the performance gap between the two?

A: The GeForce RTX 5090 Mobile wins all three shared benchmarks. It scores 5871 versus 969 in 3DMark Steel Nomad (DirectX 12), a 505.9% lead, and posts 201834 versus 52078 in Geekbench OpenCL (287.6%) and 198405 versus 49574 in Geekbench Vulkan (300.2%).

Q: Which GPU has more memory bandwidth?

A: The RTX 5090 Mobile, decisively. It pairs 24 GB of GDDR7 on a 256-bit bus for 896.0 GB/s of bandwidth, against 8 GB of GDDR6 on a 128-bit bus for 192.0 GB/s on the A1000.

Q: Can either card run DirectX 12 Ultimate titles?

A: Yes, both report DirectX 12 Ultimate (12_2) support, along with OpenGL 4.6 and Vulkan 1.4. Feature support is equal, but the 5090 Mobile delivers far higher frame delivery capacity once those features are in use.

Q: How do their compute footprints compare?

A: The 5090 Mobile delivers 31.80 TFLOPS of FP32 from 10496 shading units and 328 tensor cores; the A1000 delivers 6.737 TFLOPS from 2304 shading units and 72 tensor cores. That is close to a fivefold raw shader advantage.

Q: Which is newer?

A: The RTX A1000 shipped on 2024-04-15, while the RTX 5090 Mobile shipped on 2025-03-26. The 5090 Mobile also sits on a more advanced node, 5 nm at TSMC versus 8 nm at Samsung.

Q: Where does each sit relative to the rest of the database?

A: The 5090 Mobile ranks in the 84th percentile with an average score of 45152; the A1000 ranks in the 79th percentile with 34207. The percentile gap is modest, but the absolute and head-to-head gaps are enormous, reflecting how differently the two spreads of benchmark data are distributed.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DirectX 12 run is the most lopsided result in the set. The RTX 5090 Mobile scores 5871 against the A1000's 969, a 505.9% margin. Steel Nomad is a modern DirectX 12 stress test, and this result is the clearest single indicator of the generation-and-class gap between a Blackwell 2.0 mobile flagship and an entry-level Ampere workstation card. Where the A1000 produces a score, the 5090 Mobile produces roughly six of them.

Geekbench OpenCL tells a similar story for general GPU compute. The 5090 Mobile posts 201834 against 52078, a 287.6% advantage. That gap matters for OpenCL-accelerated workloads: rendering, simulation, and compute tasks that scale with parallel throughput will complete in a fraction of the time on the 5090 Mobile, backed by its 328 tensor cores and 31.80 TFLOPS of FP32.

Geekbench Vulkan lands between the two extremes, with the 5090 Mobile at 198405 and the A1000 at 49574, a 300.2% lead. Notably, the 5090 Mobile's OpenCL and Vulkan results are nearly identical, indicating a balanced compute stack with no API-specific weakness, while the A1000 shows a modest preference for OpenCL over Vulkan in absolute terms.

The 5090 Mobile's supplementary results reinforce the picture: a PassMark G3D score of 30034 and a PassMark GPU Compute score of 13401, neither of which has a recorded counterpart for the A1000. The verdict across every shared measurement is unanimous, three wins to zero for the 5090 Mobile, and none of the margins are close.

Specification Differences

The two cards diverge on nearly every hardware axis recorded in the database:

• Chip and architecture: GB203 on Blackwell 2.0 versus GA107 on Ampere.
• Process node and foundry: 5 nm at TSMC versus 8 nm at Samsung. The 5090 Mobile packs 45,600 million transistors on a 378 mm² die (120.6M per mm²); the A1000 has 8,700 million transistors on 200 mm² (43.5M per mm²), roughly 2.8 times the density advantage for Blackwell.
• Clocks: base 990 MHz and boost 1515 MHz for the 5090 Mobile, versus 727 MHz base and 1462 MHz boost for the A1000. Memory clocks run at 1750 MHz (28 Gbps effective) versus 1500 MHz (12 Gbps effective).
• Memory: 24 GB GDDR7 on a 256-bit bus with 896.0 GB/s, versus 8 GB GDDR6 on 128 bits with 192.0 GB/s.
• Shader resources: 10496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, 328 tensor cores, versus 2304 shading units, 72 TMUs, 32 ROPs, 18 RT cores, 72 tensor cores.
• Throughput: 169.7 GPixel/s and 496.9 GTexel/s versus 46.78 GPixel/s and 105.3 GTexel/s; FP32 of 31.80 TFLOPS versus 6.737 TFLOPS, both with 1:1 FP16.
• Power and form: 95 W TDP in an IGP form factor with no power connectors, versus 50 W TDP in a single-slot card measuring 163 mm by 69 mm, also with no power connectors and a 250 W suggested PSU.
• Bus and outputs: PCIe 5.0 x16 with portable-device-dependent display output, versus PCIe 4.0 x8 with four mini-DisplayPort 1.4a connectors.
• Lineage: the 5090 Mobile succeeds the GeForce 40 Mobile series; the A1000 descends from Quadro Turing and is succeeded by Workstation Ada.
• Release dates: 2025-03-26 for the 5090 Mobile, 2024-04-15 for the A1000.

Architecture Differences

Blackwell 2.0 and Ampere represent different eras of NVIDIA silicon, and the recorded data quantifies the distance between them. The 5090 Mobile's GB203 die, built on TSMC's 5 nm process, achieves 120.6 million transistors per square millimeter, nearly triple the 43.5M per mm² density of the A1000's Samsung 8 nm GA107. Density translates directly into resources here: the 5090 Mobile fields about 4.6 times the shading units, 4.6 times the TMUs, 3.5 times the ROPs, and roughly 4.6 times the tensor cores of the A1000.

The RT core count gap, 82 versus 18, is proportionally even larger than the shader gap, consistent with the 505.9% Steel Nomad blowout in a DirectX 12 Ultimate workload where ray tracing throughput matters. Memory subsystems also reflect the generational split: GDDR7 at 28 Gbps effective on a wide 256-bit bus against GDDR6 at 12 Gbps effective on 128 bits, producing 896.0 GB/s versus 192.0 GB/s, a 4.7-fold bandwidth advantage that compounds the compute lead when working sets exceed 8 GB, a scenario the A1000's capacity simply cannot cover.

Both GPUs report identical API support, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so software compatibility is not a differentiator. The differences are entirely in scale, node, and memory technology, not feature flags. The A1000's four mini-DisplayPort 1.4a outputs and PCIe 4.0 x8 interface target multi-display workstation duty, while the 5090 Mobile's PCIe 5.0 x16 link and device-dependent display path reflect its integration into a portable platform.

The Verdict

For anyone whose priority is performance, the recorded data makes the choice unambiguous. The GeForce RTX 5090 Mobile wins every shared benchmark by margins between 287.6% and 505.9%, offers three times the memory capacity and roughly 4.7 times the bandwidth, and lands in the 84th percentile of all GPUs in the database, trading blows with desktop-class rivals like the RTX 4070 Ti. Gamers, compute users, and creators who need the fastest available mobile silicon should pick it.

The RTX A1000 earns its place under a different set of constraints. It is a single-slot, 50 W workstation card with a small 163 mm by 69 mm footprint, no auxiliary power connectors, and a 250 W suggested PSU, designed for compact professional systems rather than performance leadership. Its results, a 79th percentile average score of 34207, competitive with the RTX A2000 12 GB and TITAN V, are respectable for its envelope. Buyers fitting a low-power, space-constrained workstation with quad mini-DisplayPort output should pick the A1000. Everyone else, per the measurements recorded here, belongs on the 5090 Mobile side of the ledger.
