The Verdict

The benchmark database shows a clear split between these two end-of-life mobile graphics solutions. For users prioritizing raw compute throughput in OpenCL workloads, the NVIDIA GeForce GT 755M is the superior choice. Its head-to-head victory in Geekbench OpenCL, with a 7.8% margin over the Intel HD Graphics P530, is reinforced by its substantially higher pixel rate, texture rate, and FP32 performance.

However, the Intel HD Graphics P530 is not without merit. Its average benchmark score of 4560 is actually higher than the NVIDIA part's 4033 average, despite losing the specific OpenCL head-to-head. This discrepancy suggests that the Intel part performs more consistently across different benchmark types, while the NVIDIA part's score is heavily weighted toward OpenCL. The Intel GPU also supports DirectX 12 (12_1) and Vulkan 1.3, compared to the NVIDIA GPU's DirectX 12 (11_0) and Vulkan 1.2.175, giving it a more modern API feature set.

For systems where power efficiency is critical, the Intel HD Graphics P530's 15 W TDP is a decisive advantage over the NVIDIA GeForce GT 755M's 50 W TDP. The Intel part is an integrated solution, requiring no additional power connectors and relying on system memory, while the NVIDIA part is a discrete MXM module with dedicated GDDR5 memory.

The data indicates that the NVIDIA GeForce GT 755M should be chosen for users who need maximum compute throughput in OpenCL-heavy applications and can accommodate its higher power draw. The Intel HD Graphics P530 is preferable for users who value API modernity, lower power consumption, and more consistent average performance across varied workloads. Neither part excels in the overall GPU hierarchy, with both sitting near the bottom quartile of all GPUs, but they serve different niches within that low-performance segment.

Head-to-Head Benchmarks

The only recorded head-to-head benchmark between these two GPUs is Geekbench OpenCL, and the results favor the NVIDIA GeForce GT 755M. The NVIDIA part scores 4934, while the Intel HD Graphics P530 scores 4549, yielding a delta of 7.8% in favor of the NVIDIA GPU.

This OpenCL result aligns with the raw compute specifications. The NVIDIA GeForce GT 755M delivers 783.4 GFLOPS of FP32 performance, more than double the Intel HD Graphics P530's 384.0 GFLOPS. The NVIDIA GPU also has double the shading units (384 versus 192), double the texture mapping units (32 versus 16), and more than five times the ROPs (16 versus 3).

However, the average benchmark scores tell a more nuanced story. The Intel HD Graphics P530's average score of 4560 is 13.1% higher than the NVIDIA GeForce GT 755M's average of 4033. This means that outside of OpenCL, the Intel part tends to perform better relative to its own peak, while the NVIDIA part's average is dragged down by weaker results in other benchmark categories.

The nearest rivals for each GPU further illustrate their positioning. The Intel HD Graphics P530 sits within 1.3% of the AMD FirePro W4190M (4505), and is nearly tied with the AMD Radeon RX 560 (4569) and AMD Radeon R5 M230 (4577). The NVIDIA GeForce GT 755M is within 1.5% of the AMD Radeon RX 9060 XT 8 GB (4093), and is nearly tied with the Intel HD Graphics 630 (4075) and AMD FirePro M4150 (4013).

For users focused solely on OpenCL performance, the NVIDIA GeForce GT 755M is the clear winner. For users looking at overall benchmark averages, the Intel HD Graphics P530 holds an advantage, suggesting better balanced performance across different test scenarios.

Specification Differences

The two GPUs differ in nearly every core specification. The Intel HD Graphics P530 has 192 shading units, 16 TMUs, and 3 ROPs, while the NVIDIA GeForce GT 755M has 384 shading units, 32 TMUs, and 16 ROPs. This gives the NVIDIA part exactly double the shading units and TMUs, and over five times the ROP count.

Clock speeds also differ significantly. The Intel HD Graphics P530 has a base clock of 350 MHz and a boost clock of 1000 MHz. The NVIDIA GeForce GT 755M has a base clock of 980 MHz and a boost clock of 1020 MHz. The NVIDIA part's base clock is nearly three times higher than the Intel part's base clock, though the boost clocks are much closer.

Memory configurations are fundamentally different. The Intel HD Graphics P530 uses system shared memory, with the bus width and bandwidth listed as system dependent. The NVIDIA GeForce GT 755M has 2 GB of GDDR5 memory on a 128-bit bus, with a bandwidth of 86.40 GB/s and an effective memory clock of 5.4 Gbps.

The TDP difference is substantial: 15 W for the Intel part versus 50 W for the NVIDIA part. The Intel GPU is an IGP with a ring bus interface, while the NVIDIA GPU is an MXM module with a PCIe 3.0 x16 interface. The NVIDIA part has no power connectors, while the Intel part requires none by virtue of being integrated. Display outputs are motherboard dependent for the Intel part and portable device dependent for the NVIDIA part.

Process nodes also differ, with the Intel part built on a 14 nm+ process by Intel, and the NVIDIA part built on a 28 nm process by TSMC. The die sizes are close: 123 mm² for the Intel part and 118 mm² for the NVIDIA part, but the NVIDIA chip contains 1,270 million transistors compared to no listed transistor count for the Intel part. The NVIDIA part has a transistor density of 10.8M per mm².

Architecture Differences

The Intel HD Graphics P530 is built on the Skylake GT2 chip, using Intel's Generation 9.0 architecture, also referred to as HD Graphics-W (Skylake). The NVIDIA GeForce GT 755M uses the GK107 chip, based on the Kepler architecture, belonging to the GeForce 700M generation.

The Intel part supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The NVIDIA part supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. This gives the Intel GPU a higher feature level in DirectX and a newer Vulkan version. The NVIDIA part also supports Metal, as evidenced by its Geekbench Metal score of 3132, while the Intel part has no recorded Metal benchmark.

In terms of compute capabilities, the NVIDIA GeForce GT 755M has an FP32 rate of 783.4 GFLOPS and no listed FP16 support. The Intel HD Graphics P530 has an FP32 rate of 384.0 GFLOPS and an FP16 rate of 768.0 GFLOPS, with a 2:1 ratio, indicating it can process half-precision data at twice the rate of full-precision data.

The Intel part's pixel rate is 3.000 GPixel/s and its texture rate is 16.00 GTexel/s. The NVIDIA part's pixel rate is 8.160 GPixel/s and its texture rate is 32.64 GTexel/s. These rates are direct consequences of the different ROP and TMU counts, combined with the respective clock speeds.

Release dates differ by over two years: the Intel HD Graphics P530 was released on 2015-08-31, while the NVIDIA GeForce GT 755M was released on 2013-06-24. The NVIDIA part lists the GeForce 600M as its predecessor and GeForce 800M as its successor, while the Intel part has no listed predecessor or successor.

The manufacturing processes are distinct: Intel uses a 14 nm+ node at its own foundry, while NVIDIA uses a 28 nm node at TSMC. The Intel die size is 123 mm², slightly larger than the NVIDIA die size of 118 mm², despite the NVIDIA chip containing more transistors, which explains its lower transistor density of 10.8M per mm² compared to no listed density for the Intel part.
