NVIDIA GeForce RTX 4080 SUPER vs NVIDIA RTX A1000 Mobile Comparison

The NVIDIA GeForce RTX 4080 SUPER and the NVIDIA RTX A1000 Mobile occupy opposite ends of the GPU spectrum, and the benchmark data reflects a decisive performance hierarchy. The RTX 4080 SUPER wins every head-to-head test by a staggering margin, while the RTX A1000 Mobile is a low-power, mobile-first part. For any user prioritizing raw compute, the RTX 4080 SUPER is the clear choice; for power-constrained, portable workloads, the RTX A1000 Mobile is the only option that fits. The data shows the RTX 4080 SUPER leads by 349.8% in Geekbench OpenCL and 455.9% in Geekbench Vulkan, making it the unequivocal performance leader.

The Verdict

The verdict is unambiguous: the NVIDIA GeForce RTX 4080 SUPER is the superior GPU for all performance-oriented tasks. Its average benchmark score of 54209 places it in the 86th percentile of all GPUs, while the RTX A1000 Mobile scores 47743, sitting at the 85th percentile. Despite the close percentile ranking, the raw score gap is enormous—the RTX 4080 SUPER delivers 13.5% higher average performance than the RTX A1000 Mobile. In direct comparisons, the RTX 4080 SUPER achieves 219065 in Geekbench OpenCL versus 48703 for the RTX A1000 Mobile, and 260075 versus 46782 in Geekbench Vulkan. These deltas of 349.8% and 455.9% respectively demonstrate that the RTX 4080 SUPER is not just faster; it is in a different performance class altogether.

The RTX A1000 Mobile, however, is not without purpose. It is an end-of-life mobile GPU with a 60 W TDP and an integrated form factor (IGP), designed for portability and low power draw. Its nearest rivals include the AMD Radeon RX 6800 XT (1.5% behind), AMD Radeon RX 6550M (2.2% ahead), Intel Arc A530M (2.4% ahead), and AMD Radeon RX 5600M (2.5% ahead), showing it competes in a modest mid-range bracket. For users who need a GPU in a thin, portable device without external power connectors, the RTX A1000 Mobile is the pick. For everyone else, the RTX 4080 SUPER’s performance is non-negotiable.

Architecture Differences

The two GPUs are built on fundamentally different architectures and manufacturing processes. The RTX 4080 SUPER uses the AD103 chip based on Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. It packs 45,900 million transistors into a 379 mm² die, yielding a transistor density of 121.1M per mm². In contrast, the RTX A1000 Mobile uses the GA107 chip based on Ampere architecture, built on an 8 nm process at Samsung. It contains 8,700 million transistors on a 200 mm² die, with a density of 43.5M per mm². This means the RTX 4080 SUPER has over five times the transistor count and nearly double the die size, reflecting its far higher compute capacity.

Feature-wise, the RTX 4080 SUPER includes 80 RT cores and 320 tensor cores, while the RTX A1000 Mobile has 16 RT cores and 64 tensor cores. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The RTX 4080 SUPER uses GDDR6X memory, whereas the RTX A1000 Mobile uses GDDR6, a difference that impacts bandwidth significantly. The RTX 4080 SUPER’s memory clock runs at 1438 MHz with 23 Gbps effective speed, while the RTX A1000 Mobile’s memory clock is 1375 MHz with 11 Gbps effective. These architectural choices explain the performance chasm: the RTX 4080 SUPER is a desktop-class powerhouse, while the RTX A1000 Mobile is a efficiency-focused mobile part.

Head-to-Head Benchmarks

The head-to-head data is sparse but conclusive, with only two shared benchmarks, both won by the RTX 4080 SUPER. In Geekbench OpenCL, the RTX 4080 SUPER scores 219065 against the RTX A1000 Mobile’s 48703, a delta of 349.8%. This indicates the RTX 4080 SUPER is roughly 4.5 times faster in OpenCL compute workloads, a signal of its 10240 shading units versus 2048, and its 52.22 TFLOPS FP32 performance against 4.669 TFLOPS.

In Geekbench Vulkan, the gap widens further. The RTX 4080 SUPER scores 260075, while the RTX A1000 Mobile manages 46782, yielding a 455.9% delta. This suggests Vulkan workloads, often used in gaming and real-time rendering, benefit even more from the RTX 4080 SUPER’s architecture. The RTX 4080 SUPER’s pixel rate of 285.6 GPixel/s and texture rate of 816.0 GTexel/s dwarf the RTX A1000 Mobile’s 36.48 GPixel/s and 72.96 GTexel/s, explaining the Vulkan advantage. There are no benchmark wins for the RTX A1000 Mobile in any shared test; the wins tally stands at 2-0 in favor of the RTX 4080 SUPER.

Specification Differences

The specification gap between these two GPUs is vast, and every field where they differ reinforces the RTX 4080 SUPER’s dominance. The RTX 4080 SUPER has 16 GB of GDDR6X memory on a 256-bit bus, delivering 736.3 GB/s bandwidth. The RTX A1000 Mobile has 4 GB of GDDR6 on a 128-bit bus, yielding 176.0 GB/s—a 4x reduction in capacity and 4.2x reduction in bandwidth. The shading unit count is 10240 versus 2048, TMUs are 320 versus 64, and ROPs are 112 versus 32. The RT 4080 SUPER’s FP32 compute is 52.22 TFLOPS, while the RTX A1000 Mobile manages just 4.669 TFLOPS, an 11.2x difference.

Power and physical specs also diverge sharply. The RTX 4080 SUPER has a TDP of 320 W, requires a triple-slot cooler and a 1x 16-pin power connector, with a suggested PSU of 700 W. It measures 310 mm in length, 140 mm in height, and 61 mm in width. The RTX A1000 Mobile is an IGP with a 60 W TDP, no power connectors, and no specified dimensions, designed to be soldered onto a laptop motherboard. The RTX 4080 SUPER uses PCIe 4.0 x16, while the RTX A1000 Mobile uses PCIe 4.0 x8. Both are end-of-life products, but the RTX 4080 SUPER launched in 2024-01-30 with a launch MSRP of 999 USD, while the RTX A1000 Mobile launched in 2022-03-29 with no MSRP listed.

Where Each One Wins

The RTX 4080 SUPER wins in every benchmark category where both are tested, but its strengths extend beyond raw scores. In Geekbench OpenCL and Vulkan, it dominates with 349.8% and 455.9% leads, respectively. Its 16 GB GDDR6X memory and 736.3 GB/s bandwidth make it ideal for high-resolution texture workloads, AI inference (with 320 tensor cores), and ray tracing (with 80 RT cores). The 52.22 TFLOPS FP32 compute is suited for scientific simulation, 3D rendering, and heavy gaming at high settings. The data shows it also performs well in Passmark tests, scoring 34245 in G3D and 19822 in GPU Compute, though these are not compared head-to-head.

The RTX A1000 Mobile wins in the domain of power efficiency and portability, a category not captured by raw benchmark scores. With a 60 W TDP and IGP form factor, it can run in devices where a 320 W, triple-slot GPU is physically impossible. Its 4 GB GDDR6 memory and 176.0 GB/s bandwidth suffice for light workloads like 2D rendering, basic video playback, and low-end 3D tasks. Its nearest rivals—AMD Radeon RX 6550M, Intel Arc A530M, and AMD Radeon RX 5600M—show it is competitive within its power class, with deltas of 2.2%, 2.4%, and 2.5% respectively. For mobile professionals needing GPU acceleration without a power brick, the RTX A1000 Mobile is the only viable choice from this comparison.
