GPU Comparison

NVIDIA GeForce GTX 1630 vs Intel Arc B580: A comparison of two graphics cards that occupy entirely different performance tiers. The GTX 1630 is an end-of-life Turing-era entry card, while the Arc B580 is an active Battlemage-generation mainstream card with a launch MSRP of 249 USD. Benchmark data shows the Intel card winning all shared tests by overwhelming margins.

The Verdict

The data presents a clear hierarchy. For any user deciding between these two cards, the Intel Arc B580 is the overwhelming choice based on raw performance. In the two benchmarks both cards share, Geekbench OpenCL and Vulkan, the B580 leads by 73.2% and 78.4%, respectively. There is no single metric in the FACT PACK where the GTX 1630 comes out ahead. The GTX 1630 sits at the 70th percentile of all GPUs, while the B580 sits at the 68th; their average benchmark scores are 24,277 and 23,021, respectively. This means the GTX 1630 actually has a slightly higher overall percentile rank, but that rank is based on a smaller benchmark set and does not reflect the head-to-head results where the B580 dominates.

Choose the GTX 1630 only if constraints like power delivery, physical size, or legacy interface compatibility are absolute dealbreakers. It draws a 75 W TDP, requires no power connectors, is single-slot, and measures 145 mm in length. It also uses a PCIe 3.0 x16 interface. The Arc B580, by contrast, demands a 190 W TDP, a single 8-pin connector, a suggested 450 W PSU, is dual-slot, and measures 272 mm. If your system can physically and electrically accommodate the B580, the benchmark results make the decision obvious.

Architecture Differences

The GTX 1630 uses the TU117 chip built on Turing architecture, manufactured by TSMC on a 12 nm process. It contains 4,700 million transistors on a 200 mm² die, yielding a transistor density of 23.5M per mm². It has no dedicated ray tracing cores and no tensor cores.

The Intel Arc B580 uses the BMG-G21 chip built on Xe2-HPG architecture, manufactured by TSMC on a 5 nm process. It contains 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1M per mm². It has 20 ray tracing cores and no tensor cores listed.

The B580 uses a second-generation Intel GPU architecture focused on efficiency and feature completeness. It supports DirectX 12 Ultimate (12_2), while the GTX 1630 supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The B580's transistor density is over three times higher, reflecting the more advanced 5 nm node.

The B580 has five times the shading units, five times the TMUs, and five times the ROPs compared to the GTX 1630.

Head-to-Head Benchmarks

The shared benchmark data shows a one-sided contest. In Geekbench OpenCL, the GTX 1630 scores 24,858 while the Arc B580 scores 92,821. The delta is -73.2%, meaning the B580 performs roughly 3.7 times better. In Geekbench Vulkan, the GTX 1630 scores 23,695 while the B580 scores 109,672. The delta is -78.4%, meaning the B580 performs roughly 4.6 times better.

The Arc B580 also has results in other benchmark suites that the GTX 1630 lacks entirely. In Passmark G3D, it scores 15,748. In Passmark GPU Compute, it scores 7,729. In 3DMark Steel Nomad DX12, it scores 3,068. These additional data points confirm the B580 is a much more capable card across multiple testing methodologies.

The GTX 1630's only benchmark entries are the two Geekbench tests, both of which it loses decisively. Its average benchmark score of 24,277 is derived from those two results. The B580's average score of 23,021 is pulled down by its Passmark DirectX tests (9, 10, 11, 12 scores ranging from 76 to 183), which are likely not directly comparable to its other results. Even with that drag, the B580's OpenCL and Vulkan scores are so far ahead that the comparison remains unambiguous.

Where Each One Wins

Intel Arc B580, performance-critical workloads. Every single benchmark in the shared set goes to the B580. Its 12 GB memory and 456.0 GB/s bandwidth suit modern game assets and compute tasks. Its 20 ray tracing cores enable hardware-accelerated ray tracing, a feature the GTX 1630 lacks entirely. The B580's FP32 throughput of 13.67 TFLOPS is roughly 7.5 times that of the GTX 1630. For any workload that stresses GPU compute, texture throughput, or pixel fill rate, the B580 is the clear winner. It also supports DirectX 12 Ultimate, which includes features like mesh shaders and variable rate shading, compared to the GTX 1630's DirectX 12_1 support.

NVIDIA GeForce GTX 1630, constrained legacy systems. The GTX 1630 wins on physical and electrical compatibility. Its 75 W TDP means it runs off the PCIe slot alone, with no auxiliary power connector needed. Its 145 mm length, single-slot profile, and 18 mm width fit in small form factor cases. Its PCIe 3.0 x16 interface works in older motherboards. Its 4 GB memory and 96.00 GB/s bandwidth are modest but sufficient for low-resolution or older titles. The card is end-of-life, so it is not a future-proof option, but for a system that cannot accommodate a dual-slot, 272 mm, 190 W card, the GTX 1630 is the only one of the two that will physically work.

The data does not support any scenario where the GTX 1630 outperforms the B580 in compute or graphics benchmarks. Its only advantages are form factor, power draw, and interface compatibility. If those constraints apply, the GTX 1630 is a functional choice. If they do not, the B580 is the superior card by every measurable metric in the FACT PACK.
