GPU Comparison

Intel HD Graphics 530 and NVIDIA GeForce 920M are both end-of-life mobile graphics solutions that land in the 20th percentile of all GPUs, placing them firmly in entry-level territory. The data shows two very different design philosophies: Intel’s integrated Skylake GT2 slice versus NVIDIA’s discrete Kepler 2.0 chip. While their average benchmark scores are nearly identical, the head-to-head results reveal a clear split in API-specific performance that defines their respective strengths.

Head-to-Head Benchmarks

The benchmark database includes two direct comparisons between these GPUs, and the results are lopsided in favor of the NVIDIA GeForce 920M. In Geekbench OpenCL, the 920M scores 3725 against the HD Graphics 530’s 3550, a 4.7% advantage. That is a modest but consistent lead, indicating the discrete GPU’s higher shading unit count and dedicated memory bandwidth translate into better raw compute throughput. The gap widens dramatically in Geekbench Vulkan, where the 920M nearly doubles Intel’s score: 2849 versus 1422, a 50.1% deficit for the integrated part. This is the single biggest differentiator in the entire comparison, the NVIDIA chip is fully twice as fast in this modern graphics API.

The Vulkan result is particularly telling because it suggests the 920M’s architecture handles driver-level overhead and parallel workload submission far more efficiently. Intel’s HD Graphics 530 does not just lose this test; it loses by a margin that rivals the performance gap between entire GPU tiers. The OpenCL test, by contrast, shows both parts are in the same ballpark, with the 920M’s 4.7% edge being the kind of difference that might go unnoticed in real-world applications. Notably, the HD Graphics 530 has no Vulkan score in its individual benchmark list beyond the head-to-head, while the 920M’s OpenCL score of 3725 is its higher individual result, reinforcing that NVIDIA’s part is consistently stronger in compute-heavy workloads.

Looking at the broader rival context, the 920M’s average score of 3287 places it just 0.9% behind the NVIDIA GeForce GT 730M (3316) and 2.4% ahead of the NVIDIA GeForce GT 640 (3210). The HD Graphics 530’s average of 3332 puts it 0.5% ahead of the GT 730M and 1.7% ahead of the Intel HD Graphics P4600 (3389 is the rival’s score, meaning the 530 is 1.7% behind that Intel part). These deltaPct values confirm that both GPUs sit in a tightly packed cluster of similar-performance parts, but the Vulkan head-to-head is the outlier that separates them.

The Verdict

Based strictly on benchmark results, the NVIDIA GeForce 920M is the superior choice for any workload that leverages Vulkan. The 50.1% lead in that test is decisive and cannot be offset by Intel’s modest 1.4% average score advantage. For users running modern games or applications that utilize Vulkan, the 920M is the only rational pick, the performance difference is akin to moving up an entire GPU class. The 920M also holds a consistent, if smaller, edge in OpenCL, making it the better option for general compute tasks.

The Intel HD Graphics 530’s only statistical advantage is its higher average benchmark score (3332 vs 3287), but this is driven by its Geekbench Metal score of 5025, a test the 920M does not have a recorded result for. That Metal score suggests the Intel part may be better suited for Apple-specific ecosystems, but since the 920M lacks a Metal benchmark, this cannot be directly compared. For most users, the 920M’s head-to-head wins, particularly the Vulkan blowout, outweigh Intel’s aggregate average. The data clearly favors the discrete NVIDIA solution for gaming and compute, while the Intel part is a fallback option with no benchmark victories.

Specification Differences

The two GPUs diverge significantly in almost every hardware category. The Intel HD Graphics 530 is built on a 14 nm+ process at Intel’s foundry, while the NVIDIA GeForce 920M uses a 28 nm process at TSMC. This gives Intel a density advantage, with the 530’s 123 mm² die size versus the 920M’s 87 mm², but NVIDIA packs more transistors: 1,020 million versus Intel’s unspecified count. Clock speeds differ sharply: the 920M runs at a fixed 954 MHz base and boost, while the 530 idles at 350 MHz and boosts to 950 MHz, meaning the NVIDIA part sustains its speed while Intel’s is variable.

Memory is a fundamental split. The 920M has 2 GB of dedicated DDR3 on a 64-bit bus with 14.40 GB/s bandwidth, whereas the 530 uses system-shared memory with system-dependent bandwidth. The 920M’s memory clock is 900 MHz (1800 Mbps effective), while the 530’s is also system-shared. Compute resources favor NVIDIA: 384 shading units, 32 TMUs, and 8 ROPs versus Intel’s 192 shading units, 24 TMUs, and just 3 ROPs. This results in NVIDIA leading in pixel rate (7.632 GPixel/s vs 2.850 GPixel/s), texture rate (30.53 GTexel/s vs 22.80 GTexel/s), and FP32 throughput (732.7 GFLOPS vs 364.8 GFLOPS). The 530 does support FP16 at 729.6 GFLOPS (2:1 ratio), a feature the 920M lacks. Power draw also differs: the 920M is rated at 33 W TDP versus the 530’s 15 W.

Architecture Differences

The Intel HD Graphics 530 is based on the Skylake GT2 chip using Intel’s Generation 9.0 architecture, with a process node of 14 nm+. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The NVIDIA GeForce 920M uses the GK208B chip with Kepler 2.0 architecture, manufactured at 28 nm by TSMC, and supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. Intel’s architecture has a higher API feature level for DirectX (12_1 vs 11_0), but NVIDIA’s Kepler design is fundamentally a discrete GPU with its own memory interface (PCIe 3.0 x8) versus Intel’s Ring Bus integration.

The 920M’s architecture is derived from the GeForce 900M generation and succeeds the GeForce 800M, while the 530 comes from the HD Graphics (Skylake) generation. Neither part has ray tracing or tensor cores. The 920M’s transistor density is listed at 11.7M per mm², a figure that reflects its older 28 nm process. Intel’s 14 nm+ process allows for a larger die (123 mm²) but with fewer functional units, suggesting the 530 dedicates more silicon to non-GPU functions typical of an integrated solution. The 920M’s fixed 954 MHz boost clock across all cores, versus the 530’s variable 350-950 MHz range, indicates NVIDIA’s architecture prioritizes sustained throughput over power saving.

Where Each One Wins

The NVIDIA GeForce 920M wins decisively in Vulkan-based applications, as shown by its 2849 score versus Intel’s 1422. This makes it the clear choice for modern game engines that adopt Vulkan for cross-platform rendering, where the 50.1% advantage translates to noticeably higher frame rates. The 920M also wins in OpenCL compute tasks, albeit by a smaller 4.7% margin, making it preferable for GPU-accelerated productivity workloads like video encoding or physics simulations. Its dedicated 2 GB VRAM and 14.40 GB/s bandwidth give it a structural advantage in texture-heavy scenes that exceed system memory bandwidth limits.

The Intel HD Graphics 530 has no benchmark wins in the head-to-head data, but its higher average score (3332 vs 3287) is driven by a Geekbench Metal score of 5025, which the 920M lacks. This suggests the Intel part may be better suited for macOS environments where Metal is the primary graphics API, though no direct comparison exists. The 530’s lower 15 W TDP also makes it a better fit for ultra-portable devices where battery life and thermals are priorities over raw performance. Its FP16 support (729.6 GFLOPS) could be an advantage in AI inference tasks that use half-precision, but the 920M’s absence of FP16 data makes this a speculative edge. In summary, the 920M is the winner for gaming and compute, while the 530’s niche lies in low-power integrated scenarios with no Vulkan demands.
