Intel UHD Graphics 750 vs NVIDIA GeForce GT 555M Comparison

Where Each One Wins

The Intel UHD Graphics 750 and the NVIDIA GeForce GT 555M are both end-of-life mobile graphics solutions, but they belong to very different eras and design philosophies. The recorded benchmark data shows a single head-to-head comparison, and in that test, the Intel part takes the win. However, the broader database entries reveal distinct strengths that matter depending on the workload.

The Intel UHD Graphics 750 wins the only direct comparison available: the Geekbench OpenCL test. Its score of 6,743 edges out the GT 555M's 6,493 by 3.9%. This is a modest margin, but it indicates that the integrated Intel solution, despite sharing system memory, can keep pace with and slightly exceed a dedicated discrete GPU from a decade earlier. The Intel part also has a second recorded benchmark, Geekbench Vulkan, where it scores 8,138, a figure that underscores its modern API support and compute capability.

The NVIDIA GeForce GT 555M, by contrast, has no recorded wins in the head-to-head data. Its advantage lies not in raw compute scores but in its dedicated memory architecture. With 1,024 MB of dedicated DDR3 memory on a 128-bit bus, it delivers 28.80 GB/s of bandwidth. The Intel UHD Graphics 750 relies on "System Shared" memory, with bandwidth listed as "System Dependent." For workloads that are sensitive to memory latency and bandwidth, the dedicated frame buffer of the GT 555M can be the deciding factor, even if the compute throughput is lower.

In terms of architectural efficiency, the Intel part is built on a 14 nm+++ process at Intel, while the GT 555M uses TSMC's 40 nm node. This process gap translates directly into power draw: the Intel IGP is rated at 15 W, whereas the GT 555M consumes 35 W. For a laptop user prioritizing battery life and thermals, the Intel solution is the clear winner. For a user who needs a fixed, dedicated memory pool and does not care about power efficiency, the GT 555M retains relevance in legacy systems.

The percentile data reinforces this split. The Intel UHD Graphics 750 sits at the 40th percentile of all GPUs in the database, with an average benchmark score of 7,441. The GT 555M sits at the 37th percentile with an average score of 6,493. The Intel part is also positioned very close to several discrete rivals: it trails the AMD Radeon HD 8850M by only 0.1%, leads the AMD Radeon R7 350 by 0.2%, trails the NVIDIA GeForce GTX 1650 by 0.4%, and trails the Intel Arc A310 by 1.4%. The GT 555M's nearest rivals include the NVIDIA Quadro M5000M (0.2% ahead), the AMD Radeon Vega 10 Mobile (0.3% ahead), the NVIDIA GeForce GTX 670M (0.3% behind), and the Intel UHD Graphics P750 (0.9% behind). These numbers show that the Intel UHD Graphics 750 competes with a higher tier of GPUs, while the GT 555M is clustered with older mobile parts.

Head-to-Head Benchmarks

The only direct benchmark comparison in the database is the Geekbench OpenCL test. The Intel UHD Graphics 750 records a score of 6,743, while the NVIDIA GeForce GT 555M records 6,493. The delta is 3.9% in favor of the Intel part. This is a narrow but clear victory. In a compute-heavy workload that uses OpenCL, the integrated Intel GPU outperforms the dedicated Fermi-era NVIDIA chip.

Looking at the broader benchmark picture, the Intel UHD Graphics 750 also has a Geekbench Vulkan score of 8,138. This is not a head-to-head result because the GT 555M has no Vulkan score in the database, but it demonstrates that the Intel part is capable of leveraging modern graphics APIs to produce higher compute scores. The average benchmark score for the Intel part is 7,441, which is the mean of its two recorded results. The GT 555M's average is 6,493, which is its single OpenCL score.

The percentile rankings put these numbers into context. The Intel UHD Graphics 750 is at the 40th percentile of all GPUs. The GT 555M is at the 37th percentile. These are close, but the Intel part is slightly better positioned. The nearest rival data for the Intel part shows it is essentially tied with the AMD Radeon HD 8850M (0.1% behind) and the AMD Radeon R7 350 (0.2% ahead), and it is within 1.4% of the Intel Arc A310. The GT 555M is similarly close to its rivals, with the NVIDIA Quadro M5000M at 0.2% ahead and the AMD Radeon Vega 10 Mobile at 0.3% ahead.

In raw throughput terms, the Intel UHD Graphics 750 delivers 665.6 GFLOPS of FP32 compute, while the GT 555M delivers 339.8 GFLOPS. That is nearly double the compute throughput. The Intel part also has a higher pixel rate (10.40 GPixel/s vs. 3.540 GPixel/s) and a higher texture rate (20.80 GTexel/s vs. 14.16 GTexel/s). These figures are not from the head-to-head table but from the specification data, and they explain why the Intel part wins the OpenCL test despite having a shared memory pool.

Specification Differences

The two GPUs differ across nearly every major specification category. The Intel UHD Graphics 750 uses a 14 nm+++ process node from Intel, while the NVIDIA GeForce GT 555M uses a 40 nm node from TSMC. The GT 555M has a transistor count of 1,170 million and a die size of 238 mm², with a transistor density of 4.9M per mm². The Intel part does not have transistor or die size data recorded.

Clock speeds also differ. The Intel part has a base clock of 300 MHz and a boost clock of 1,300 MHz. The GT 555M has no base or boost clock recorded, only a memory clock of 900 MHz (1,800 Mbps effective). The memory configuration is a major differentiator: the GT 555M has 1,024 MB of DDR3 on a 128-bit bus with 28.80 GB/s bandwidth, while the Intel part uses System Shared memory with System Dependent bandwidth.

The compute units differ as well. The Intel UHD Graphics 750 has 256 shading units, 16 TMUs, and 8 ROPs. The GT 555M has 144 shading units, 24 TMUs, and 16 ROPs. The Intel part has higher FP32 throughput (665.6 GFLOPS vs. 339.8 GFLOPS) and supports FP16 at 1,331.2 GFLOPS (2:1 ratio), while the GT 555M has no FP16 data recorded.

Power consumption is a stark difference: the Intel part is rated at 15 W TDP, the GT 555M at 35 W. The bus interface also differs: the Intel part uses a Ring Bus (being an integrated processor graphics solution), while the GT 555M uses PCIe 2.0 x16. Display outputs are Motherboard Dependent for the Intel part and Portable Device Dependent for the GT 555M.

Architecture Differences

The Intel UHD Graphics 750 is built on the Generation 12.1 architecture, part of the Rocket Lake chip. This is a modern, unified architecture that supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The GT 555M is based on the Fermi architecture, using the GF106 chip, which is part of the GeForce 500M generation. It supports DirectX 12 (11_0) and OpenGL 4.6, but has no Vulkan support.

The process node gap is enormous: 14 nm+++ for Intel versus 40 nm for TSMC. This explains the power efficiency difference (15 W vs. 35 W) and likely contributes to the Intel part's higher clock speeds (1,300 MHz boost vs. no boost data for the GT 555M). The Intel architecture also includes FP16 support at a 2:1 ratio, which is absent from the GT 555M's recorded specifications.

The GT 555M has a dedicated memory interface with a 128-bit bus and 28.80 GB/s bandwidth, a hallmark of discrete GPU design from its era. The Intel UHD Graphics 750 relies on shared system memory, which is typical for integrated graphics but now performs competitively due to modern memory controllers. The GT 555M's predecessor is the GeForce 400M, and its successor is the GeForce 600M, whereas the Intel part has no predecessor or successor listed in the database.

In terms of feature set, the Intel architecture is clearly newer and more capable in API support. The GT 555M's Fermi architecture is a decade older and lacks modern compute features like Vulkan. The Intel part also has a higher pixel rate (10.40 GPixel/s) and texture rate (20.80 GTexel/s), which are direct consequences of its higher clocks and more modern shader design. The GT 555M counters with more TMUs (24 vs. 16) and ROPs (16 vs. 8), which are fixed-function units that can help in certain rendering scenarios, but the overall architectural advantage belongs to the Intel part.
