NVIDIA RTX A1000 Mobile vs NVIDIA RTX A500 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a clear pattern of superiority for the NVIDIA RTX A1000 Mobile across both benchmark tests. In Geekbench OpenCL, the A1000 Mobile scores 48,703 points against 41,263 points for the RTX A500 Mobile, a delta of 18 percent in favor of the A1000. The Vulkan test widens the gap further: the A1000 Mobile reaches 46,782 points while the A500 Mobile manages only 37,873 points, producing a 23.5 percent advantage for the A1000. These are not marginal differences; they represent substantial performance separation between two mobile workstation GPUs from the same generation.

The average benchmark score reinforces the trend. The RTX A1000 Mobile posts an average of 47,743 across the two tests, while the RTX A500 Mobile averages 39,568. The A1000 Mobile sits at the 85th percentile among all GPUs in the database, whereas the A500 Mobile is at the 82nd percentile. Both are strong performers, but the A1000 Mobile is measurably closer to the top of the distribution. The head-to-head win count is decisive: the A1000 Mobile wins 2 tests, the A500 Mobile wins 0.

Interpreting these numbers requires context from the nearest rivals. The A1000 Mobile's average score of 47,743 places it just 1.5 percent behind the AMD Radeon RX 6800 XT, which averages 48,477. It is 2.2 percent ahead of the AMD Radeon RX 6550M, 2.4 percent ahead of the Intel Arc A530M, and 2.5 percent ahead of the AMD Radeon RX 5600M. This is a tight cluster, meaning the A1000 Mobile performs essentially at parity with several desktop-class and high-end mobile GPUs, despite being a low-power mobile part.

The A500 Mobile's average of 39,568 sits in a different competitive neighborhood. It is exactly level with the AMD Radeon Pro 575 at 39,555, effectively a 0 percent delta. It is 1.2 percent ahead of the AMD Radeon Pro 575X, 1.2 percent behind the AMD Radeon Pro WX 7100 which scores 40,063, and 1.9 percent behind the AMD Radeon Pro 580 at 40,318. The A500 Mobile is thus grouped with previous-generation professional mobile GPUs, while the A1000 Mobile competes with newer and more powerful parts.

The per-test deltas also tell a story about scaling. The A1000 Mobile's OpenCL lead of 18 percent is smaller than its Vulkan lead of 23.5 percent. Both tests show the same winner, but Vulkan appears to favor the A1000 Mobile's architecture more strongly. Alternatively, the A500 Mobile's Vulkan implementation may be relatively weaker. Either way, the data indicates that the A1000 Mobile's advantage is consistent across API boundaries, not an artifact of one particular workload.

Where Each One Wins

The RTX A1000 Mobile wins every recorded benchmark, so there is no category where the A500 Mobile comes out ahead in the database. However, the nature of the wins differs by workload. In OpenCL, the A1000 Mobile is 18 percent faster, which is a substantial margin for compute-oriented tasks such as rendering, simulation, or data processing. In Vulkan, the lead grows to 23.5 percent, suggesting that graphics-heavy applications that leverage modern APIs will see an even larger benefit from choosing the A1000 Mobile.

For users running OpenCL workloads, the A1000 Mobile's advantage is clear but not overwhelming. An 18 percent improvement could translate to noticeably shorter render times or faster compute jobs, depending on the application's scaling behavior. For Vulkan-based workloads, the 23.5 percent delta is more decisive, potentially meaning nearly a quarter more throughput in graphics tasks or game development environments that use Vulkan.

The A500 Mobile's wins are zero, so its role is not defined by benchmark superiority. Instead, the recorded data shows it as a lower-performance option within the same family. The A500 Mobile does have a higher boost clock on paper, which is discussed in the specification section, but the benchmark results do not translate that clock advantage into actual performance gains. The A500 Mobile's 30 W TDP versus the A1000 Mobile's 60 W TDP suggests a power efficiency trade-off, but the database contains no efficiency metrics, only absolute scores.

In practical terms, the A1000 Mobile is the choice for anyone who needs maximum compute and graphics performance per the recorded data. The A500 Mobile might be suitable for lighter workloads where the 30 W power draw is a priority, but the benchmark database does not include any test where the A500 Mobile demonstrates a performance win. Every recorded measurement favors the A1000 Mobile, and the margins are significant enough to affect real-world responsiveness in demanding applications.

The Verdict

The data is unambiguous: the NVIDIA RTX A1000 Mobile outperforms the NVIDIA RTX A500 Mobile in every recorded benchmark. The A1000 Mobile leads by 18 percent in OpenCL and 23.5 percent in Vulkan, with an average score advantage of 20.6 percent relative to the A500 Mobile's average. For users who prioritize raw performance in mobile workstation GPUs, the A1000 Mobile is the clear pick based on the database.

The A500 Mobile is not without merit. Its nearest rivals include AMD Radeon Pro parts that are within 1.9 percent of its average score, indicating that it is a competent performer in its own tier. For users who need a low-power GPU at 30 W rather than 60 W, the A500 Mobile offers a power draw reduction without changing the core architecture. However, the database shows no performance scenario where the A500 Mobile wins, so any selection of the A500 Mobile must be based on other factors such as system thermal constraints or battery life considerations, neither of which are quantified in the benchmark data.

The A1000 Mobile's placement relative to rivals is also notable. It sits within 2.5 percent of four different AMD and Intel GPUs, including the RX 6800 XT, which is a desktop-class part. This means the A1000 Mobile delivers performance that rivals much larger and more power-hungry GPUs, despite its 60 W TDP and IGP form factor. The A500 Mobile, by contrast, competes with older AMD Radeon Pro mobile parts, placing it in a lower performance tier.

For buyers, the recommendation depends on the workload. If the primary use is OpenCL or Vulkan compute, the A1000 Mobile provides a measurable advantage that justifies its higher power draw. If the system must run at 30 W, the A500 Mobile is the only option between the two, but the recorded data shows a meaningful performance cost for that power saving. The verdict is straightforward: the A1000 Mobile wins on every measured axis, and the A500 Mobile is the alternative for power-constrained designs.

Architecture Differences

Both GPUs are built on the Ampere architecture using Samsung's 8 nm process node, and both share the same underlying silicon characteristics. Each chip contains 8,700 million transistors on a 200 mm² die, resulting in a transistor density of 43.5 million transistors per square millimeter. The core configurations are identical in terms of compute units: both have 2,048 shading units, 64 texture mapping units, 32 raster operation units, 16 ray tracing cores, and 64 tensor cores. This means the architectural capability per clock is the same; the differences in performance come from clock speeds and memory configuration.

The RTX A1000 Mobile uses the GA107 chip, while the RTX A500 Mobile uses the GA107S variant. The "S" designation typically indicates a modified or binned version of the same die, though the recorded specifications do not detail specific changes beyond clock and memory behavior. Both are integrated graphics processors (IGP) with no power connectors, and both use a PCIe 4.0 x8 bus interface. Display outputs are listed as "Portable Device Dependent" for both, meaning the video output capabilities are determined by the laptop or mobile device rather than the GPU itself.

A notable architectural difference is in clock strategy. The A500 Mobile runs a base clock of 832 MHz and a boost clock of 1537 MHz, which is significantly higher than the A1000 Mobile's base clock of 630 MHz and boost clock of 1140 MHz. Despite the higher clocks, the A500 Mobile produces lower benchmark scores, which is explained by its narrower memory interface and lower memory bandwidth. The A500 Mobile's memory clock is 1500 MHz (12 Gbps effective), but its bus width is only 64 bit, yielding 96.00 GB/s of bandwidth. The A1000 Mobile has a 128 bit bus with a memory clock of 1375 MHz (11 Gbps effective), producing 176.0 GB/s, nearly double the bandwidth.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The FP32 and FP16 compute rates are identical within each GPU at a 1:1 ratio, with the A1000 Mobile delivering 4.669 TFLOPS and the A500 Mobile delivering 6.296 TFLOPS. This means the A500 Mobile has a higher theoretical compute throughput, but the benchmark data shows it cannot translate that into real-world wins, likely due to memory bandwidth limitations. The pixel rate and texture rate follow the clock speeds: the A500 Mobile posts 49.18 GPixel/s and 98.37 GTexel/s, while the A1000 Mobile posts 36.48 GPixel/s and 72.96 GTexel/s. Again, the A500 Mobile has higher fill rates on paper, yet loses in every benchmark.

Specification Differences

The two GPUs differ in several key specification fields. The chip designation is different: GA107 for the A1000 Mobile versus GA107S for the A500 Mobile. Base clock speeds differ, with the A1000 Mobile at 630 MHz and the A500 Mobile at 832 MHz. Boost clocks also differ, with the A1000 Mobile at 1140 MHz and the A500 Mobile at 1537 MHz. Memory clock differs as well: the A1000 Mobile runs at 1375 MHz (11 Gbps effective), while the A500 Mobile runs at 1500 MHz (12 Gbps effective).

Memory bus width is a major differentiator: the A1000 Mobile uses a 128 bit bus, while the A500 Mobile uses a 64 bit bus. Consequently, memory bandwidth is 176.0 GB/s for the A1000 Mobile versus 96.00 GB/s for the A500 Mobile. Both have 4 GB of GDDR6 memory, so the capacity is identical, but the bandwidth difference is substantial.

Compute rates differ despite identical core counts. The A1000 Mobile delivers 4.669 TFLOPS in FP32 and FP16, while the A500 Mobile delivers 6.296 TFLOPS in both. Pixel rate is 36.48 GPixel/s for the A1000 Mobile and 49.18 GPixel/s for the A500 Mobile. Texture rate is 72.96 GTexel/s for the A1000 Mobile and 98.37 GTexel/s for the A500 Mobile.

Power consumption is a significant difference: the A1000 Mobile has a TDP of 60 W, while the A500 Mobile has a TDP of 30 W. Both are IGP form factors with no power connectors. Release dates are close, with the A1000 Mobile released on 2022-03-29 and the A500 Mobile on 2022-03-21. Both are end-of-life products, with the same predecessor (Quadro Turing-M) and successor (Ada-MW) in the database. Neither has a launch MSRP recorded, so no pricing information is available. The A1000 Mobile's percentile rank is 85 versus 82 for the A500 Mobile, and the average benchmark scores are 47,743 and 39,568 respectively.
