Intel HD Graphics 530 vs NVIDIA GeForce 830M Comparison

The NVIDIA GeForce 830M and the Intel HD Graphics 530 occupy the same crowded entry-level territory, but the recorded data suggests they are not as evenly matched as their class implies. Both are integrated solutions, both are end-of-life parts, and both sit low in the database percentile rankings. Yet across the head-to-head measurements available, the Maxwell-based 830M wins every shared contest, sometimes dramatically. What follows is a closer look at where that gap comes from, and whether the Intel part's newer process node changes the picture.

Head-to-Head Benchmarks

Only two tests appear in both records, and the GeForce 830M takes both. In Geekbench OpenCL the 830M scores 4324 against the HD Graphics 530's 3550, a 21.8 percent advantage. That is a meaningful but not overwhelming lead, the kind of margin that shows up as noticeably smoother low-settings gaming rather than a different category of performance.

The Vulkan result is far more lopsided. The 830M records 3590 while the HD Graphics 530 manages 1422, a 152.5 percent gap, meaning the NVIDIA part delivers roughly two and a half times the throughput in that API. A delta this large raises questions about driver maturity as much as raw hardware. The 830M supports Vulkan 1.4 while the Intel part tops out at Vulkan 1.3, and the database scores suggest the NVIDIA software stack extracts far more from the newer graphics API.

There is one wrinkle worth investigating: the HD Graphics 530 holds a Geekbench Metal score of 5025, the single highest number in either record. Metal is an Apple-platform API and the 830M has no corresponding entry, so no direct comparison is possible. Still, it hints that the Intel part's compute performance is not uniformly weak, and that the head-to-head picture is shaped by which APIs each benchmark exercises.

Context from each part's neighborhood reinforces the split. The 830M's average benchmark score of 3957 places it in a dead heat with the AMD Radeon R5 M420 (3956, a 0 percent delta), essentially level with the GeForce GT 745M (3953, 0.1 percent), and within touching distance of the Quadro K2000 (3964, -0.2 percent) and the Radeon HD 6850 X2 (3977, -0.5 percent). The HD Graphics 530, averaging 3332, sits in a lower cluster: within 0.5 percent of the GeForce GT 730M, 1.4 percent above the GeForce 920M, but trailing the HD Graphics P4600 by 1.7 percent and the GT 740 by 2.9 percent. Against the full database, the 830M lands in the 24th percentile of all GPUs while the HD Graphics 530 sits at the 20th, a modest four-point spread that nonetheless matches the benchmark outcomes.

Architecture Differences

On paper these two parts come from different design philosophies. The GeForce 830M is a dedicated GPU die, codenamed GM108, built on NVIDIA's Maxwell architecture for the GeForce 800M generation. It was fabricated by TSMC on a 28 nm process, packs 1,020 million transistors into a 77 mm² die, and yields a transistor density of 13.2 million per square millimetre. The HD Graphics 530 is Intel's Skylake GT2, a Generation 9.0 integrated graphics unit etched on Intel's own 14 nm+ node within a 123 mm² die. No transistor count or density figure is recorded for the Intel part, so a direct efficiency comparison at the silicon level is not possible from this data.

The resource split is curious. The 830M carries 256 shading units, 16 texture mapping units, and 8 render output units, against the Intel part's 192 shading units, 24 TMUs, and just 3 ROPs. Those ROP counts translate into stark theoretical rates: 9.200 GPixel/s for the NVIDIA versus 2.850 GPixel/s for the Intel, a better than three-to-one pixel-fill advantage. Texture fill rate flips the story, with the HD Graphics 530's 22.80 GTexel/s beating the 830M's 18.40 GTexel/s thanks to its higher TMU count. Compute likewise splits both ways: FP32 throughput favors NVIDIA at 588.8 GFLOPS versus 364.8 GFLOPS, while the Intel part's FP16 rate of 729.6 GFLOPS at a 2:1 ratio is a capability the 830M record does not list at all.

Clock behavior differs sharply. The 830M runs a base clock of 1082 MHz with a modest boost to 1150 MHz. The HD Graphics 530 starts at 350 MHz and boosts to 950 MHz, a far wider dynamic range that reflects the shared power budget of an integrated design. Memory is the other structural divide: the 830M has its own 2 GB of DDR3 on a 64-bit bus running at 900 MHz (1800 Mbps effective) for 14.40 GB/s of dedicated bandwidth, while the HD Graphics 530 shares system memory in every respect, with size, type, bus width, and bandwidth all dependent on the host platform.

Power envelopes are not comparable in the usual sense, but the recorded figures stand: 33 W for the 830M against 15 W for the HD Graphics 530. Bus interfaces also diverge, with the NVIDIA part using PCIe 3.0 x8 and the Intel unit communicating over a Ring Bus. Feature support splits along API lines: both support DirectX 12 and OpenGL 4.6, but the 830M claims feature level 11_0 under DirectX 12 and Vulkan 1.4, while the HD Graphics 530 reaches the more complete feature level 12_1 but stops at Vulkan 1.3. The 830M shipped in March 2014 as part of the line between GeForce 700M and GeForce 900M successors; the HD Graphics 530 arrived in August 2015 with no recorded predecessor or successor.

Where Each One Wins

The GeForce 830M's victories map cleanly onto its hardware strengths. The 152.5 percent Vulkan lead and 21.8 percent OpenCL lead, combined with its superior pixel fill rate and higher FP32 throughput, point to low-resolution gaming and general GPU compute as its territory. Its dedicated video memory, though modest at 14.40 GB/s, removes it from contention with the CPU for bandwidth, which matters in the kinds of systems where these parts appear. Its database neighborhood, clustered against the R5 M420 and GT 745M, confirms it performs like a true entry-level discrete GPU.

The HD Graphics 530's case rests on different pillars. Its higher texture fill rate and FP16 throughput at 729.6 GFLOPS suggest it can hold its own in workloads that lean on texturing or half-precision compute, and its 5025 Geekbench Metal score is the strongest single benchmark number either part records. Its 15 W envelope and Ring Bus integration make it the inherently simpler solution, and its feature level 12_1 support under DirectX 12 exceeds what the 830M offers. For anything bound by the ROP count, though, its 2.850 GPixel/s rate is a hard ceiling.

FAQ

Q: Which GPU is faster overall?

A: The NVIDIA GeForce 830M. It won both head-to-head benchmarks, leading by 21.8 percent in Geekbench OpenCL (4324 vs 3550) and 152.5 percent in Geekbench Vulkan (3590 vs 1422), and its average benchmark score of 3957 exceeds the HD Graphics 530's 3332.

Q: How do they rank against all GPUs in the database?

A: The GeForce 830M sits in the 24th percentile versus the HD Graphics 530's 20th percentile, so both are entry-level parts, but the NVIDIA unit ranks somewhat higher.

Q: Does the Intel GPU have any performance advantages?

A: Yes, in select metrics. It delivers a higher texture fill rate (22.80 vs 18.40 GTexel/s) and lists FP16 throughput of 729.6 GFLOPS, which the 830M record does not include. It also posted a Geekbench Metal score of 5025, though the 830M has no Metal result for comparison.

Q: Which uses less power?

A: The HD Graphics 530, with a recorded TDP of 15 W versus the 830M's 33 W.

Q: How do their memory configurations differ?

A: The 830M has 2 GB of dedicated DDR3 on a 64-bit bus with 14.40 GB/s of bandwidth. The HD Graphics 530 shares system memory entirely, so its capacity and bandwidth depend on the host system.

Q: Which supports newer graphics features?

A: It splits. The 830M supports Vulkan 1.4 versus Intel's 1.3, but the HD Graphics 530 supports DirectX 12 feature level 12_1 versus the 830M's 11_0. Both support OpenGL 4.6.

The Verdict

The data is unambiguous on raw performance: the GeForce 830M is the faster GPU, winning every shared benchmark and holding a higher average score and percentile ranking. Buyers or system evaluators prioritizing GPU throughput for gaming or compute, particularly under Vulkan where the gap reaches 152.5 percent, should favor the 830M.

The HD Graphics 530 argues for itself on efficiency and integration. Half the recorded TDP, no dependence on a PCIe slot, a newer 14 nm+ process, and stronger texture-side and FP16 figures make it the more frugal choice where power and thermals dominate. Its feature level 12_1 DirectX support is also more forward-looking than the 830M's 11_0.

Neither part is a strong performer by modern standards, sitting at the 24th and 20th percentiles of the database respectively. But between the two, the recorded results give the performance edge decisively to the Maxwell-based NVIDIA design, while the Skylake Intel unit remains defensible where its efficiency and feature strengths align with the workload.
