A: The RTX PRO 2000 Blackwell uses the GB206 chip on a 5 nm TSMC process with 21,900 million transistors on a 181 mm² die. The RTX A5000 Mobile uses the GA104 chip on Samsung's 8 nm process with 17,400 million transistors on a 392 mm² die. The Blackwell chip achieves a transistor density of 121.0M/mm² versus 44.4M/mm² for Ampere.

Q: Which GPU has better memory bandwidth?

A: The RTX A5000 Mobile has significantly higher memory bandwidth at 448.0 GB/s due to its 256-bit bus, compared to 288.0 GB/s for the RTX PRO 2000 Blackwell's 128-bit bus. However, the Blackwell GPU uses faster GDDR7 memory at 18 Gbps effective, versus GDDR6 at 14 Gbps effective for the A5000.

The Verdict

The data is unambiguous: the NVIDIA RTX PRO 2000 Blackwell wins 8 of 9 head-to-head benchmarks against the NVIDIA RTX A5000 Mobile. The overall average score favors the Blackwell card by 2% (25,269 vs 24,763), and its percentile ranking matches the A5000 at 70. The verdict is that the RTX PRO 2000 Blackwell is the superior performer for virtually all modern workloads, despite being a newer, more power-efficient design.

For professionals working in Vulkan-based applications, the choice is especially clear, the Blackwell card's 29.2% lead in Geekbench Vulkan is decisive. For DirectX workloads, the Blackwell GPU leads by 11.1% in DirectX 12, 30.8% in DirectX 11, 42.6% in DirectX 9, and 6.1% in DirectX 10. The only scenario where the RTX A5000 Mobile should be considered is if a specific application relies heavily on OpenCL compute, where the older card leads by 4.3%.

The RTX PRO 2000 Blackwell also wins decisively in 2D performance (107.2% higher Passmark G2D score) and GPU compute (20.9% higher Passmark GPU Compute score). Its 27.1% advantage in Passmark G3D confirms that the Blackwell architecture extracts more real-world gaming and rendering performance per unit of raw hardware.

Head-to-Head Benchmarks

The largest single win for the RTX PRO 2000 Blackwell comes in the Passmark G2D test, where it scores 1,303 versus 629 for the A5000 Mobile, a 107.2% advantage. This indicates dramatically better 2D acceleration and desktop compositing performance, which matters for professional workstation use with multiple high-resolution displays.

In DirectX 9, the Blackwell GPU scores 241 versus 169, a 42.6% lead. This is notable because legacy DirectX 9 workloads remain common in CAD and some engineering applications. The DirectX 11 gap is nearly as large at 30.8% (174 vs 133), which covers a broad range of professional visualization tools that still render through DX11 paths.

The Vulkan result is striking: 113,865 for Blackwell versus 88,144 for A5000, a 29.2% lead. Vulkan is increasingly important for modern rendering engines, and this result suggests the Blackwell architecture has substantially better low-level API efficiency. The Passmark G3D score of 20,049 versus 15,779 (27.1% lead) confirms that the Blackwell card delivers better overall 3D rendering throughput.

In DirectX 12, the gap narrows to 11.1% (80 vs 72), but Blackwell still wins. The Passmark GPU Compute test shows a 20.9% advantage (8,396 vs 6,945), indicating better general-purpose compute performance despite the A5000's larger raw shader count.

The RTX A5000 Mobile's sole victory is in Geekbench OpenCL, scoring 110,877 versus 106,087 (4.3% lead). This is a modest margin compared to the Blackwell GPU's wins, and it appears to be an outlier given the A5000's losses in every other compute-oriented test.

Specification Differences

The RTX PRO 2000 Blackwell and RTX A5000 Mobile differ substantially in their specifications. The Blackwell card has 4,352 shading units, 136 TMUs, and 48 ROPs, while the A5000 Mobile has 6,144 shading units, 192 TMUs, and 96 ROPs. Despite having fewer execution resources, the Blackwell GPU achieves competitive performance.

Clock speeds differ significantly: the Blackwell GPU runs at a 982 MHz base and 1,957 MHz boost, versus 900 MHz base and 1,575 MHz boost for the A5000 Mobile. The higher boost clock on Blackwell partially compensates for its lower core count.

Memory configurations are notably different. The RTX PRO 2000 Blackwell uses 16 GB of GDDR7 on a 128-bit bus with 288.0 GB/s bandwidth. The RTX A5000 Mobile also has 16 GB, but uses GDDR6 on a 256-bit bus with 448.0 GB/s bandwidth. The A5000's wider memory bus gives it a 55.6% bandwidth advantage, but the Blackwell card's faster GDDR7 memory helps close the gap.

Power consumption is a major differentiator: the Blackwell GPU has a 70 W TDP, while the A5000 Mobile draws 150 W. This makes the Blackwell card more than twice as power-efficient per watt. The Blackwell card is a dual-slot design measuring 167 mm x 69 mm x 20 mm, while the A5000 Mobile has no fixed dimensions as it's a mobile component.

The bus interface differs as well: PCIe 5.0 x8 for Blackwell versus PCIe 4.0 x16 for the A5000 Mobile. The Blackwell card offers four mini-DisplayPort 2.1b outputs, while the A5000 Mobile's display outputs are portable device dependent.

Architecture Differences

The RTX PRO 2000 Blackwell is built on the Blackwell 2.0 architecture using the GB206 chip, fabricated on TSMC's 5 nm process. The RTX A5000 Mobile uses the older Ampere architecture with the GA104 chip on Samsung's 8 nm process. This process difference is significant: the 5 nm node allows 21,900 million transistors on a 181 mm² die, achieving a density of 121.0M/mm². The 8 nm Ampere chip packs 17,400 million transistors but requires a much larger 392 mm² die, with a density of only 44.4M/mm².

The Blackwell architecture includes 34 RT cores and 136 tensor cores, while the Ampere GPU has 48 RT cores and 192 tensor cores. Despite having fewer specialized cores, the Blackwell GPU delivers higher or comparable performance in most tests, indicating architectural efficiency gains.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Blackwell card achieves pixel rate of 93.94 GPixel/s and texture rate of 266.2 GTexel/s, while the A5000 Mobile offers 151.2 GPixel/s and 302.4 GTexel/s. The A5000's higher fill rates reflect its larger ROP and TMU counts.

In terms of FP32 compute, the A5000 Mobile lists 19.35 TFLOPS versus 17.03 TFLOPS for the Blackwell card, and both achieve 1:1 FP16 performance. However, the benchmark results show that the Blackwell GPU's lower theoretical throughput translates to better real-world results in most tests, suggesting architectural improvements in scheduling and instruction efficiency.

The production status differs: the RTX PRO 2000 Blackwell is Active, while the RTX A5000 Mobile is End-of-life. The Blackwell GPU was released in 2025, whereas the A5000 Mobile launched in 2021. The A5000 Mobile's predecessor was Quadro Turing-M, and its successor is Ada-MW, while the Blackwell card's predecessor is Workstation Ada.

Where Each One Wins

The RTX PRO 2000 Blackwell wins in nearly every measurable category. Its most dominant victories are in 2D performance (107.2% lead in Passmark G2D), legacy DirectX 9 (42.6% lead), and Vulkan (29.2% lead). These results make it the clear choice for professional workstation users who rely on desktop rendering, older CAD applications, or modern Vulkan-based software.

For modern 3D workloads, the Blackwell card's 27.1% lead in Passmark G3D and 20.9% lead in GPU compute make it the better option for rendering, simulation, and general compute tasks. Its DirectX 11 lead of 30.8% covers most professional visualization tools, and its DirectX 12 lead of 11.1% ensures future compatibility with newer applications.

The RTX A5000 Mobile's single win in Geekbench OpenCL (4.3% lead) suggests it may be preferable for specific OpenCL compute workloads. Its higher memory bandwidth (448.0 GB/s vs 288.0 GB/s) and larger memory bus (256-bit vs 128-bit) could also make it more suitable for applications that are extremely memory-bandwidth-sensitive, even though the benchmark data doesn't show a clear advantage in tested scenarios.

The power efficiency of the RTX PRO 2000 Blackwell (70 W TDP vs 150 W) makes it the obvious choice for mobile workstations where battery life and thermal management are critical. The Blackwell card achieves better overall performance while drawing less than half the power, which is a significant practical advantage.

For users migrating from older Ampere-based systems, the RTX PRO 2000 Blackwell represents a straightforward upgrade path with better performance across most tests, a more compact dual-slot design, and PCIe 5.0 support. The A5000 Mobile remains viable only for legacy OpenCL-centric workflows or scenarios where its higher memory bandwidth is specifically required.
