NVIDIA RTX A1000 Mobile vs NVIDIA RTX A6000 Comparison

Head-to-Head Benchmarks

The benchmark data presents a stark contrast between these two NVIDIA Ampere professional GPUs. Across the two shared tests in the database, the NVIDIA RTX A6000 wins decisively in both, leaving the RTX A1000 Mobile with zero wins in head-to-head comparisons. The most dramatic margin appears in the Geekbench OpenCL test, where the A6000 scores 193,937 points against the A1000 Mobile's 48,703 points. This translates to a delta of -74.9% for the mobile part, meaning the A6000 delivers nearly four times the raw compute throughput in this particular workload.

The gap narrows somewhat in the Geekbench Vulkan test, though it remains lopsided. The A6000 posts 164,462 points, while the A1000 Mobile manages 46,782 points. The delta here is -71.6%, still a massive deficit for the mobile GPU. It is importantly the A1000 Mobile's Vulkan score is actually slightly higher relative to its OpenCL result than the A6000's is, suggesting the mobile part's driver overhead or architecture scaling behaves somewhat differently across APIs. However, in absolute terms, the workstation card's advantage is overwhelming in both scenarios.

When placed against their respective nearest rivals, the two GPUs occupy surprisingly similar competitive positions despite the vast performance chasm between them. The A1000 Mobile's average benchmark score of 47,743 places it just 1.5% behind the AMD Radeon RX 6800 XT, which averages 48,477 points. That is a remarkably close margin for a mobile professional GPU competing against a desktop enthusiast card. The A1000 Mobile also edges out the AMD Radeon RX 6550M by 2.2%, the Intel Arc A530M by 2.4%, and the AMD Radeon RX 5600M by 2.5%. These single-digit deltas indicate the A1000 Mobile sits right at the boundary between competitive tiers, trading blows with both older desktop flagships and modern mobile mid-range parts.

The A6000, meanwhile, averages 44,075 points across its benchmark suite, sitting just 0.9% behind the NVIDIA GeForce RTX 4090 Mobile and 1.6% behind the NVIDIA GeForce RTX 4070 Ti. It also leads the NVIDIA Quadro M6000 by 1.8% and the NVIDIA GeForce RTX 5050 Mobile by 1.9%. The A6000's percentile rank of 84 versus the A1000 Mobile's 85 is curious — despite the A6000 being vastly faster in raw scores, its percentile placement is one point lower, reflecting how the two parts are evaluated against different pools of contemporary GPUs. The A1000 Mobile's 85th percentile suggests it outperforms 85% of all GPUs in the database, which is remarkable for a 60 W mobile part.

Where Each One Wins

The data paints a clear picture of specialization. The RTX A6000 wins every single benchmark where both parts appear, and its victories are not marginal — they are transformative. In OpenCL, the A6000's 193,937 points versus the A1000 Mobile's 48,703 shows a GPU designed for sustained, heavy compute workloads. The A6000's 84 RT cores, 336 tensor cores, and 38.71 TFLOPS of FP32 throughput make it a compute monster, and the benchmark results confirm this. For professionals running GPU-accelerated rendering, simulation, machine learning inference, or any workload that scales with raw shading and tensor performance, the A6000 is categorically superior.

The RTX A1000 Mobile wins in a different arena: efficiency and portability. With a 60 W TDP and IGP (integrated graphics processor) form factor, it is designed to fit into mobile workstations where power and space are constrained. The A6000, by contrast, demands 300 W, a dual-slot cooler, and an 8-pin EPS power connector with a suggested 700 W power supply. The A1000 Mobile's 4 GB of GDDR6 memory on a 128-bit bus delivers 176.0 GB/s of bandwidth — modest but adequate for its target workloads. The A6000's 48 GB on a 384-bit bus provides 768.0 GB/s, over four times the bandwidth. For users who need GPU acceleration on the move, the A1000 Mobile's portability is its winning attribute, even though its raw performance lags dramatically.

The benchmark data also suggests different use-case optimizations. The A6000's PassMark suite results — 22,577 in G3D, 14,110 in GPU compute, and notably 913 in G2D — indicate strong 2D and 3D workstation performance. The A1000 Mobile has no equivalent PassMark entries in the database, limiting direct comparison, but its Geekbench scores show it is competitive with desktop cards like the RX 6800 XT in OpenCL despite its mobile form factor. This suggests the A1000 Mobile punches above its weight class in compute-heavy tasks, even if it cannot approach the A6000's absolute throughput.

Specification Differences

The specification gap between these two Ampere GPUs is enormous. The RTX A1000 Mobile uses the GA107 chip with 8,700 million transistors on a 200 mm² die. The RTX A6000 uses the GA102 chip with 28,300 million transistors on a 628 mm² die. Transistor density is similar — 43.5M per mm² for the mobile part versus 45.1M per mm² for the workstation card — but the sheer scale difference is substantial.

Clock speeds diverge significantly. The A1000 Mobile runs at a base clock of 630 MHz and boosts to 1140 MHz, while the A6000 operates at 1410 MHz base and 1800 MHz boost. Memory clocks also differ: the A1000 Mobile uses 1375 MHz (11 Gbps effective) GDDR6, while the A6000 runs at 2000 MHz (16 Gbps effective). The A6000's higher clocks are enabled by its 300 W TDP, versus the A1000 Mobile's 60 W.

The compute resources are in entirely different leagues. The A1000 Mobile has 2,048 shading units, 64 TMUs, and 32 ROPs. The A6000 has 10,752 shading units, 336 TMUs, and 112 ROPs. RT cores number 16 on the mobile part versus 84 on the workstation card, and tensor cores are 64 versus 336. Pixel rate is 36.48 GPixel/s on the A1000 Mobile versus 201.6 GPixel/s on the A6000. Texture rate is 72.96 GTexel/s versus 604.8 GTexel/s. FP32 and FP16 throughput are both 4.669 TFLOPS on the A1000 Mobile, while the A6000 delivers 38.71 TFLOPS in both.

Physical specifications differ as well. The A1000 Mobile is an IGP (integrated graphics processor) with no dimensions listed and portable-device-dependent display outputs. The A6000 is a dual-slot card measuring 267 mm (10.5 inches) in length and 112 mm (4.4 inches) in height, with four DisplayPort 1.4a outputs. The bus interface is PCIe 4.0 x8 on the mobile part and PCIe 4.0 x16 on the workstation card. The A6000 has a launch MSRP of 4,649 USD.

Architecture Differences

Both GPUs share the Ampere architecture, manufactured on Samsung's 8 nm process. They also share identical API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The core architectural differences lie in scale and implementation rather than fundamental design changes.

The chip-level difference is stark. The GA107 chip in the A1000 Mobile is a small, power-efficient die designed for mobile integration. The GA102 chip in the A6000 is NVIDIA's flagship workstation silicon, densely packed with compute resources. Both use the same 8 nm Samsung process, but the GA102's 28,300 million transistors versus the GA107's 8,700 million represents a 3.25x transistor budget.

The generations differ in naming: the A1000 Mobile belongs to the "Ampere-MW (Ax000)" generation, while the A6000 belongs to "Workstation Ampere (Ax000)." Their predecessors and successors also differ. The A1000 Mobile succeeds the Quadro Turing-M and is succeeded by Ada-MW. The A6000 succeeds Quadro Turing and is succeeded by Workstation Ada. This lineage reflects their different market positions — mobile workstations versus high-end desktop workstations.

Ray tracing and tensor core counts scale with the chip size. The A1000 Mobile's 16 RT cores and 64 tensor cores are sufficient for entry-level ray tracing and AI acceleration. The A6000's 84 RT cores and 336 tensor cores provide workstation-class performance for professional visualization and deep learning workloads. Both support 1:1 FP16/FP32 ratio, meaning they do not use dedicated FP16 hardware — instead, they share the same units for both precisions.

The memory architecture is a fundamental differentiator. The A1000 Mobile's 128-bit bus and 4 GB capacity suit its mobile constraints. The A6000's 384-bit bus and 48 GB capacity enable large dataset handling and multi-GPU rendering scenarios. The 768.0 GB/s bandwidth of the A6000 is over four times the A1000 Mobile's 176.0 GB/s.

The Verdict

The data supports an unambiguous conclusion: the RTX A6000 is the correct choice for users who need maximum compute performance in a workstation environment. Its 193,937 OpenCL score and 164,462 Vulkan score dwarf the A1000 Mobile's 48,703 and 46,782 respectively. With 38.71 TFLOPS FP32 performance, 48 GB of memory, and 768.0 GB/s bandwidth, the A6000 is engineered for professional workloads that demand sustained, high-throughput computation. Its 84 RT cores and 336 tensor cores make it suitable for ray-traced rendering and machine learning applications. The 300 W TDP and dual-slot form factor are acceptable trade-offs for desktop workstation users.

The RTX A1000 Mobile serves a completely different purpose. Its 60 W TDP and IGP form factor make it the only viable option for mobile workstations where the A6000 physically cannot fit. The data shows the A1000 Mobile is competitive with desktop GPUs like the AMD Radeon RX 6800 XT, trailing by just 1.5% in average score. Its 85th percentile ranking among all GPUs is remarkable for a mobile part. For professionals who need GPU acceleration while traveling or working in the field, the A1000 Mobile's 4 GB memory and 176.0 GB/s bandwidth are sufficient for moderate workloads, and its 2,048 shading units provide decent compute throughput.

The verdict is not about which GPU is "better" — the A6000 wins every benchmark category decisively. The verdict is about matching hardware to requirements. If your work demands maximum GPU compute and you have a desktop chassis with adequate power delivery, the A6000's 74.9% OpenCL advantage and 71.6% Vulkan advantage over the A1000 Mobile make it the obvious choice. If portability is non-negotiable and you need professional-grade GPU acceleration in a laptop, the A1000 Mobile's efficiency and competitive standing against much larger desktop GPUs make it a compelling option. The data shows two capable Ampere GPUs serving opposite ends of the workstation spectrum.
