NVIDIA GeForce GTX 1630 vs NVIDIA RTX A5000 Mobile Comparison

NVIDIA’s RTX A5000 Mobile and GeForce GTX 1630 occupy opposite ends of the performance spectrum, yet both share a place in the company’s end-of-life lineup. The data positions the RTX A5000 Mobile as a mobile workstation-class part with 16 GB of GDDR6 memory and 6,144 shading units, while the GTX 1630 is a compact desktop Turing card with 4 GB of VRAM and 512 cores. The benchmark results are not close, but the story is more nuanced than a simple landslide, given the GTX 1630’s higher base clock and the A5000 Mobile’s sheer architectural scale. This analysis relies strictly on the provided figures to interpret what each GPU does best and for whom.

Head-to-Head Benchmarks

The head-to-head data contains only two shared tests, and the RTX A5000 Mobile wins both by overwhelming margins. In Geekbench OpenCL, the A5000 Mobile scores 110,877 against the GTX 1630’s 24,858, a delta of 346%. That is not a marginal lead; it is a four-fold advantage in raw compute throughput. The Vulkan test tells a similar story: 88,144 for the A5000 Mobile versus 23,695 for the GTX 1630, a 272% difference. These are the only direct comparisons available, and they paint a clear picture of generational and class disparity.

Looking at the wider benchmark pool, the A5000 Mobile’s average score across all tests is 24,763, while the GTX 1630 averages 24,277. The difference here is just 2%, which seems contradictory to the head-to-head results. The explanation lies in the test composition: the GTX 1630 only has Geekbench OpenCL and Vulkan results recorded, while the A5000 Mobile includes a full suite of Passmark tests where it scores relatively lower (e.g., 115 in DirectX 10, 133 in DirectX 11, 72 in DirectX 12, 169 in DirectX 9). These low DirectX scores drag down the A5000 Mobile’s average, masking its compute dominance in the aggregate number. The A5000 Mobile’s Passmark G3D score of 15,779 is substantial, but its G2D score of 629 and compute score of 6,945 are not enough to offset the weak legacy DirectX numbers.

The nearest-rival data reinforces this split. For the A5000 Mobile, the closest competitor is the AMD Radeon RX 590 with an average score of 24,744 (0.1% delta), followed by the Intel Arc A350M at 24,647 (0.5%) and the AMD RX 6600 XT at 24,442 (1.3%). The GTX 1630 sits at the bottom of that list with a 2% delta. For the GTX 1630 itself, the nearest rival is the NVIDIA GTX 780 Ti at 24,236 (0.2% delta), then the RTX 2080 SUPER at 24,170 (0.4%), the RX 6600 XT at 24,442 (-0.7% delta, meaning the GTX 1630 is 0.7% behind), and the RX 6800S at 24,063 (0.9% ahead). This shows that in average benchmark terms, both cards are statistically tied with a cluster of very different GPUs, from a 2013 flagship to a 2020 enthusiast card. The individual head-to-head numbers, however, reveal the true gulf in compute capability.

The Verdict

The data leaves little room for ambiguity in raw performance: the RTX A5000 Mobile is the superior GPU for any compute-heavy task. Its 346% lead in OpenCL and 272% lead in Vulkan are decisive, and its 16 GB of memory versus 4 GB means it can handle larger datasets without swapping. The GTX 1630 does not win a single head-to-head benchmark, and its only advantage is in power draw (75 W TDP versus 150 W) and physical size (single-slot, 145 mm length versus a mobile form factor with no specified dimensions). For a desktop user needing a low-profile card for basic display output or light gaming, the GTX 1630 is functional. For anyone requiring serious compute, AI workloads, or high-resolution texture work, the A5000 Mobile is the only choice from these two.

The percentile rankings are identical at 70, which is misleading given the performance gap. This suggests that the percentile is based on the average benchmark score, which in turn is skewed by the A5000 Mobile’s poor legacy DirectX results. A user should ignore the percentile and focus on the specific workloads. The GTX 1630’s higher base clock (1,740 MHz versus 900 MHz) does not compensate for a 12x difference in shading units and a 4.6x difference in texture rate. The verdict is clear: pick the A5000 Mobile for performance, pick the GTX 1630 only if power constraints and desktop compatibility are absolute priorities.

Architecture Differences

The two GPUs come from different architectural generations and foundries. The RTX A5000 Mobile uses the GA104 chip on an 8 nm Samsung process, with 17,400 million transistors on a 392 mm² die, yielding a transistor density of 44.4 million per mm². The GTX 1630 uses the TU117 chip on a 12 nm TSMC process, with 4,700 million transistors on a 200 mm² die, for a density of 23.5 million per mm². The A5000 Mobile’s process advantage is clear: it packs nearly four times the transistors into less than double the die area.

The A5000 Mobile is built on the Ampere architecture, which includes dedicated ray tracing cores (48) and tensor cores (192). The GTX 1630 is Turing-based but lacks both RT cores and tensor cores entirely, as indicated by null values in the data. This is a fundamental difference: the A5000 Mobile can accelerate ray-traced workloads and AI inference, while the GTX 1630 relies on traditional shader math only. The A5000 Mobile supports DirectX 12 Ultimate (12_2), while the GTX 1630 is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, so API compatibility is otherwise equal.

Memory architecture diverges sharply. The A5000 Mobile has a 256-bit bus with 448.0 GB/s bandwidth, while the GTX 1630 has a 64-bit bus with 96.00 GB/s bandwidth. The memory clock is higher on the A5000 Mobile (14 Gbps effective versus 12 Gbps), but the bus width is the dominant factor. The A5000 Mobile’s FP32 throughput is 19.35 TFLOPS, compared to 1.828 TFLOPS for the GTX 1630. Interestingly, the FP16 ratio differs: the A5000 Mobile runs FP16 at 1:1 (19.35 TFLOPS), while the GTX 1630 runs FP16 at 2:1 (3.656 TFLOPS), meaning the GTX 1630’s FP16 is double its FP32 rate, a quirk of its Turing design without tensor cores.

Where Each One Wins

The RTX A5000 Mobile wins in every compute and memory-intensive scenario. Its 16 GB of GDDR6 memory is suited for large 3D scenes, machine learning models, or video editing timelines that exceed 4 GB. The 448.0 GB/s bandwidth supports high-resolution textures and multi-monitor setups without bottlenecking. The 48 RT cores enable hardware-accelerated ray tracing in supported applications, and the 192 tensor cores accelerate AI-based features like DLSS (though DLSS is not explicitly mentioned in the data, the tensor core count implies such capability). Its FP32 throughput of 19.35 TFLOPS is more than 10x the GTX 1630’s 1.828 TFLOPS, making it the obvious pick for scientific computing, rendering, and any CUDA-accelerated workload.

The GTX 1630 wins only in efficiency and physical footprint. Its 75 W TDP is half the A5000 Mobile’s 150 W, making it suitable for small form factor builds or systems with weak power supplies (the suggested PSU is 250 W). Its dimensions of 145 mm x 69 mm x 18 mm (5.7 x 2.7 x 0.7 inches) allow it to fit in tight cases, and its display outputs (1x DVI, 1x HDMI 2.0, 1x DisplayPort 1.4a) provide standard connectivity. In contrast, the A5000 Mobile’s display outputs are listed as "Portable Device Dependent," meaning it is designed for laptops and relies on the host system’s outputs. The GTX 1630’s higher base clock (1,740 MHz) may give it an edge in lightly threaded or latency-sensitive tasks, but the data shows no such benchmark wins.

Specification Differences

The two cards differ in nearly every measurable specification. The RTX A5000 Mobile uses the GA104 chip on an 8 nm Samsung process with 17,400 million transistors, while the GTX 1630 uses TU117 on a 12 nm TSMC process with 4,700 million transistors. The A5000 Mobile’s die is 392 mm² versus 200 mm². Clock speeds: the A5000 Mobile has a 900 MHz base and 1,575 MHz boost, while the GTX 1630 has a 1,740 MHz base and 1,785 MHz boost. Memory: 16 GB GDDR6 at 14 Gbps effective with a 256-bit bus (448.0 GB/s) versus 4 GB GDDR6 at 12 Gbps with a 64-bit bus (96.00 GB/s). Core counts: 6,144 shading units, 192 TMUs, 96 ROPs, 48 RT cores, and 192 tensor cores for the A5000 Mobile; 512 shading units, 32 TMUs, 16 ROPs, and no RT or tensor cores for the GTX 1630. Pixel rate: 151.2 GPixel/s versus 28.56 GPixel/s. Texture rate: 302.4 GTexel/s versus 57.12 GTexel/s. FP32: 19.35 TFLOPS versus 1.828 TFLOPS. TDP: 150 W versus 75 W. The GTX 1630 is single-slot with a 250 W suggested PSU, while the A5000 Mobile has no slot width or PSU data. Bus interface: PCIe 4.0 x16 for the A5000 Mobile, PCIe 3.0 x16 for the GTX 1630. DirectX support: 12 Ultimate (12_2) versus 12 (12_1). The GTX 1630 lists specific display outputs, while the A5000 Mobile does not.
