GPU Comparison

The NVIDIA GeForce RTX 5080 and NVIDIA RTX A1000 Mobile occupy opposite ends of the performance spectrum, and the benchmark data quantifies that gap with brutal clarity. The RTX 5080 is a desktop flagship-class card built on the Blackwell 2.0 architecture, while the RTX A1000 Mobile is an end-of-life Ampere-generation laptop part. The head-to-head results, limited to two shared test suites, show a complete sweep for the RTX 5080, with deltas that dwarf any other comparison in the database.

Head-to-Head Benchmarks

The only two benchmarks where both GPUs have recorded scores are Geekbench OpenCL and Geekbench Vulkan, and the RTX 5080 dominates both. In Geekbench OpenCL, the RTX 5080 scores 235,901 against the RTX A1000 Mobile’s 48,703, a delta of 384.4%. That is not a marginal advantage; it is a 3.84x multiplier in raw compute throughput as measured by this synthetic workload. The Vulkan results are even more lopsided: the RTX 5080 posts 255,450 versus 46,782 for the A1000 Mobile, a delta of 446%. This suggests the newer architecture scales even better in low-level API scenarios, likely leveraging its massive shader array and faster memory subsystem.

To contextualize these numbers, look at the average benchmark scores. The RTX 5080’s average across all its recorded tests is 56,083, while the RTX A1000 Mobile’s average is 47,743. That is a 17.5% gap in overall average score, but the head-to-head deltas are far larger because the A1000 Mobile’s other tests (if any existed) are not in this dataset. The RTX 5080’s percentile ranking among all GPUs is 87, while the A1000 Mobile sits at 85, a narrow 2-percentile gap that seems paradoxical given the raw score disparity. This is because percentiles reflect the distribution of all GPUs, and the A1000 Mobile, despite being a mobile part, still outperforms many older desktop cards. The RTX 5080’s nearest rivals in the database include the AMD Radeon 8060S (0.6% ahead), AMD Radeon RX 6750 GRE 12 GB (0.7% ahead), and AMD Radeon RX 9070 GRE (2.2% behind), showing it sits in a tightly contested mid-range pack. The A1000 Mobile’s rivals include the AMD Radeon RX 6800 XT (1.5% ahead) and AMD Radeon RX 6550M (2.2% behind), indicating it competes with older high-end and newer mid-range parts.

The RTX 5080 also wins in the sheer breadth of benchmark coverage: it has scores for 3DMark Steel Nomad DX12 (8,637), Passmark G3D (36,565), Passmark GPU Compute (21,789), and several DirectX-specific tests (DirectX 10: 208, DirectX 11: 324, DirectX 12: 151, DirectX 9: 389). The A1000 Mobile has no entries for any DirectX or 3DMark tests in this data, meaning its real-world gaming performance is unquantified here. This absence of data is itself a finding: the A1000 Mobile was likely never subjected to the same rigorous desktop-oriented benchmark suite, reflecting its intended use case as a professional mobile GPU rather than a gaming part.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 5080 is the superior GPU in every measurable way within this FACT PACK. It wins both head-to-head benchmarks, holds a higher average benchmark score (56,083 vs 47,743), and offers a feature set that is generations ahead. The RTX A1000 Mobile’s only advantage is its existence in a mobile form factor, it is an IGP (integrated graphics processor) with no power connectors, designed for laptops, whereas the RTX 5080 is a dual-slot desktop card requiring a 16-pin connector and a 750 W PSU.

Strictly from the data, anyone needing maximum compute performance should choose the RTX 5080. Its Geekbench OpenCL score is 384.4% higher, and its Vulkan score is 446% higher. However, the RTX A1000 Mobile is not without merit: its 85th percentile ranking shows it outperforms 85% of all GPUs in the database, and its nearest rival, the AMD Radeon RX 6800 XT, is only 1.5% ahead. For a 60 W mobile part, that is a remarkable efficiency story, though the data does not include power-per-performance metrics. The RTX 5080’s 87th percentile is only slightly higher, but the raw performance gap between the two is so vast that percentile rankings obscure the real-world difference. The verdict is simple: the RTX 5080 is for uncompromising performance; the A1000 Mobile is for constrained mobile environments where its lower power draw (60 W vs 360 W) is a necessity.

Where Each One Wins

The RTX 5080 wins in every category where data exists. In compute workloads, its Geekbench OpenCL score of 235,901 crushes the A1000 Mobile’s 48,703. In graphics API performance, its Vulkan score of 255,450 dwarfs the A1000 Mobile’s 46,782. It also has dedicated scores for DirectX 12 Ultimate (12_2), with a 3DMark Steel Nomad score of 8,637, and Passmark G3D of 36,565, none of which the A1000 Mobile can match because it has no recorded scores in those tests. The RTX 5080’s FP32 compute is rated at 56.28 TFLOPS, versus 4.669 TFLOPS for the A1000 Mobile, a 12x difference that explains the benchmark deltas. Its texture rate is 879.3 GTexel/s versus 72.96 GTexel/s, and its pixel rate is 293.1 GPixel/s versus 36.48 GPixel/s, all pointing to a GPU that is not just faster but categorically different in throughput.

The RTX A1000 Mobile wins only in the domain of physical integration. It is an IGP with no power connectors, a 60 W TDP, and a PCIe 4.0 x8 interface, making it suitable for thin-and-light professional laptops. Its memory configuration of 4 GB GDDR6 on a 128-bit bus with 176.0 GB/s bandwidth is minuscule compared to the RTX 5080’s 16 GB GDDR7 on a 256-bit bus with 960.0 GB/s, but it is sufficient for its intended workloads. The A1000 Mobile’s production status is end-of-life, while the RTX 5080 is active, meaning the former is a legacy product. If the use case is mobile professional graphics with modest demands, the A1000 Mobile has no direct competitor in this comparison because the RTX 5080 cannot physically fit in a laptop. If the use case is desktop performance, the RTX 5080 has no peer in this matchup.

Architecture Differences

The architectural gap between these two GPUs is generational and fundamental. The RTX 5080 uses the GB203 chip built on NVIDIA’s Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. It packs 45,600 million transistors into a 378 mm² die, yielding a density of 120.6 million transistors per mm². In contrast, the RTX A1000 Mobile uses the GA107 chip on the older Ampere architecture, fabricated on an 8 nm process at Samsung. It contains 8,700 million transistors on a 200 mm² die, with a density of 43.5 million per mm². This means the RTX 5080 has over 5x the transistor count on a die that is only 1.89x larger, a testament to the density improvements of Blackwell over Ampere.

The compute resources tell a similar story. The RTX 5080 has 10,752 shading units, 336 TMUs, and 112 ROPs, along with 84 RT cores and 336 tensor cores. The A1000 Mobile has 2,048 shading units, 64 TMUs, and 32 ROPs, with 16 RT cores and 64 tensor cores. That is a 5.25x difference in shading units, a 5.25x difference in TMUs, and a 3.5x difference in ROPs. The RT and tensor core counts differ by 5.25x and 5.25x respectively, showing a consistent scaling of the entire architecture. The RTX 5080’s FP32 performance is rated at 56.28 TFLOPS, while the A1000 Mobile is at 4.669 TFLOPS, a 12x gap that suggests the newer architecture also achieves better instruction-level efficiency.

Memory architecture is another major divergence. The RTX 5080 uses 16 GB of GDDR7 on a 256-bit bus, delivering 960.0 GB/s of bandwidth. The A1000 Mobile uses 4 GB of GDDR6 on a 128-bit bus, delivering 176.0 GB/s. The bandwidth difference is 5.45x, which is critical for memory-bound workloads. The RTX 5080’s memory clock is 1875 MHz (30 Gbps effective), while the A1000 Mobile’s is 1375 MHz (11 Gbps effective), showing both a higher per-pin data rate and a wider bus. The RTX 5080 also supports PCIe 5.0 x16, whereas the A1000 Mobile is limited to PCIe 4.0 x8, halving the available lanes and halving the protocol generation.

Specification Differences

The specification sheet highlights where these two GPUs diverge beyond raw performance. The process node differs: the RTX 5080 is on 5 nm, the A1000 Mobile on 8 nm. The transistor count is 45,600 million versus 8,700 million, and the die size is 378 mm² versus 200 mm². The base clock of the RTX 5080 is 2295 MHz, boosting to 2617 MHz, while the A1000 Mobile runs at a base of 630 MHz and a boost of 1140 MHz, the latter’s low clocks are typical for a power-constrained mobile part. The TDP is 360 W for the RTX 5080 versus 60 W for the A1000 Mobile, a 6x difference in power draw. The RTX 5080 requires a dual-slot cooler and a 1x 16-pin power connector, with a suggested PSU of 750 W; the A1000 Mobile is an IGP with no power connectors and no suggested PSU.

Memory specifications differ entirely: 16 GB GDDR7 on a 256-bit bus versus 4 GB GDDR6 on a 128-bit bus. The bus interface is PCIe 5.0 x16 for the RTX 5080, versus PCIe 4.0 x8 for the A1000 Mobile. Display outputs are another clear split: the RTX 5080 has 1x HDMI 2.1b and 3x DisplayPort 2.1b, while the A1000 Mobile’s outputs are listed as “Portable Device Dependent,” meaning they are determined by the laptop manufacturer. The RTX 5080 has physical dimensions of 304 mm in length, 137 mm in height, and 40 mm in width; the A1000 Mobile has no listed dimensions because it is soldered to a motherboard. The production status differs, Active for the RTX 5080, End-of-life for the A1000 Mobile, and their release dates are 2025-01-29 and 2022-03-29 respectively. The RTX 5080’s predecessor is GeForce 40, and its successor is GeForce 60; the A1000 Mobile’s predecessor is Quadro Turing-M, and its successor is Ada-MW. The RTX 5080 has a launch MSRP of 999 USD, while the A1000 Mobile has no launch MSRP listed.
