NVIDIA GeForce GT 755M vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

The Verdict

The database comparison between the NVIDIA GeForce GT 755M and the NVIDIA RTX 5000 Mobile Ada Generation is not a contest of performance tiers; it is a study in architectural eras. The GT 755M is an end-of-life Kepler part from 2013, while the RTX 5000 Mobile is an active Ada Lovelace workstation-class GPU from 2023. The recorded benchmark data, however, presents a peculiar twist: the GT 755M holds an average benchmark score of 4033, while the RTX 5000 Mobile scores 3596 in its sole recorded test. This does not mean the older card is faster; it means the two GPUs are measured by entirely different benchmark suites in the database, making direct score comparisons misleading.

For a builder or buyer, the choice is clear from the data. Pick the RTX 5000 Mobile if you need modern feature support, massive memory capacity, hardware ray tracing, tensor cores, and a GPU that is still in active production. Pick the GT 755M only if you are restoring a legacy laptop with an MXM module slot and have no need for contemporary graphics APIs or compute features. The GT 755M sits at the 24th percentile of all GPUs, while the RTX 5000 Mobile sits at the 21st percentile; both are low in the overall distribution, but the RTX 5000 Mobile's percentile is based on a single demanding DirectX 12 workload, whereas the GT 755M's percentile reflects two older compute tests. The RTX 5000 Mobile is the only rational choice for any modern workload, despite its lower raw average score in this database.

Where Each One Wins

The GT 755M wins in legacy compute benchmarks. Its Geekbench OpenCL score of 4934 and Geekbench Metal score of 3132 are the only recorded performance data points for this GPU. These tests reflect older compute paradigms and the GT 755M's Kepler architecture, which was designed for DirectX 11-era games and general-purpose compute. Its nearest rivals in the database include the AMD FirePro M4150 (0.5% slower), the Intel HD Graphics 630 (1% faster), and the AMD Radeon RX 9060 XT 8 GB (1.5% faster), indicating that the GT 755M is clustered with entry-level integrated and discrete GPUs from a decade ago.

The RTX 5000 Mobile wins in every meaningful architectural category. Its sole benchmark, 3DMark Steel Nomad DX12, is a modern DirectX 12 Ultimate workload that stresses features the GT 755M physically lacks, such as hardware ray tracing and mesh shaders. The RTX 5000 Mobile's nearest rivals in the database are the NVIDIA GeForce GT 545 (0.1% slower), the NVIDIA GeForce GT 735M (0.6% faster), and the NVIDIA GeForce GTX 1050 (0.9% faster). This clustering is an artifact of the database's limited test coverage for this mobile GPU, not a reflection of its true capability. In real-world terms, the RTX 5000 Mobile wins in any workload that uses DirectX 12 Ultimate features, large datasets, or AI acceleration. The GT 755M wins only in the narrow sense of having more recorded benchmark entries, and even then, those entries are from older, less demanding test suites.

Architecture Differences

The two GPUs represent a generational leap in nearly every hardware metric. The GT 755M uses the GK107 chip on TSMC's 28 nm process, with 1,270 million transistors packed into a 118 mm² die, yielding a transistor density of 10.8 million per square millimeter. The RTX 5000 Mobile uses the AD103 chip on TSMC's 5 nm process, with 45,900 million transistors on a 379 mm² die, yielding a density of 121.1 million per square millimeter. That is a 36-fold increase in transistor count and an 11-fold increase in density, enabling the RTX 5000 Mobile to house far more compute resources.

The GT 755M has 384 shading units, 32 texture mapping units, and 16 raster output units. It has no ray tracing cores and no tensor cores. The RTX 5000 Mobile has 9,728 shading units, 304 TMUs, and 112 ROPs, plus 76 dedicated ray tracing cores and 304 tensor cores. The pixel rate jumps from 8.160 GPixel/s on the GT 755M to 236.9 GPixel/s on the RTX 5000 Mobile, a 29-fold increase. The texture rate rises from 32.64 GTexel/s to 643.0 GTexel/s, a 19.7-fold increase. FP32 compute goes from 783.4 GFLOPS to 41.15 TFLOPS, a 52.5-fold increase. The RTX 5000 Mobile also offers FP16 at 41.15 TFLOPS with a 1:1 ratio, while the GT 755M has no recorded FP16 capability.

Memory architecture is equally divergent. The GT 755M has 2 GB of GDDR5 on a 128-bit bus, delivering 86.40 GB/s of bandwidth. The RTX 5000 Mobile has 16 GB of GDDR6 on a 256-bit bus, delivering 576.0 GB/s. The effective memory clock is 5.4 Gbps on the older card versus 18 Gbps on the newer one. The RTX 5000 Mobile supports PCIe 4.0 x16, while the GT 755M is limited to PCIe 3.0 x16. Power envelopes differ substantially: the GT 755M is rated at 50 W TDP and uses an MXM module slot, while the RTX 5000 Mobile is rated at 120 W TDP and is an integrated GPU (IGP) design, meaning it is soldered to the motherboard.

FAQ

Q: Which GPU has the higher average benchmark score in the database?

A: The GT 755M has an average benchmark score of 4033, while the RTX 5000 Mobile has an average of 3596. However, these scores come from different test suites: the GT 755M has two Geekbench results (Metal and OpenCL), while the RTX 5000 Mobile has one 3DMark Steel Nomad DX12 result.

Q: Does the RTX 5000 Mobile support hardware ray tracing?

A: Yes. The RTX 5000 Mobile has 76 dedicated ray tracing cores and 304 tensor cores. The GT 755M has none of either. The RTX 5000 Mobile also supports DirectX 12 Ultimate (12_2), while the GT 755M only reaches DirectX 12 (11_0).

Q: How do their transistor densities compare?

A: The RTX 5000 Mobile has a transistor density of 121.1 million per square millimeter on a 5 nm process. The GT 755M has a density of 10.8 million per square millimeter on a 28 nm process. The newer GPU packs over 11 times more transistors per unit area.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two GPUs. The head-to-head benchmark array is empty, with zero wins recorded for either side. This is a critical limitation of the comparison: the GT 755M's scores come from Geekbench Metal and OpenCL, while the RTX 5000 Mobile's score comes from 3DMark Steel Nomad DX12. These workloads exercise entirely different capabilities and cannot be compared numerically to declare a winner.

What the data does show is the magnitude of architectural progress. The GT 755M's best recorded score is 4934 in Geekbench OpenCL. The RTX 5000 Mobile's only recorded score is 3596 in 3DMark Steel Nomad DX12. If we look at the nearest rivals for each, the GT 755M is bracketed by the AMD FirePro M4150 (0.5% slower), the Intel HD Graphics 630 (1% faster), and the AMD Radeon RX 9060 XT 8 GB (1.5% faster). The RTX 5000 Mobile is bracketed by the NVIDIA GeForce GT 545 (0.1% slower), the NVIDIA GeForce GT 735M (0.6% faster), and the NVIDIA GeForce GTX 1050 (0.9% faster). These rival clusters are separated by less than 2% in either direction, meaning the database's measurement noise is far larger than any meaningful performance delta between these two GPUs in their respective test suites.

The real wins are in the specification sheets. The RTX 5000 Mobile delivers 41.15 TFLOPS of FP32 compute versus 783.4 GFLOPS for the GT 755M, a 52.5-fold advantage. Its texture rate of 643.0 GTexel/s is 19.7 times higher. Its pixel rate of 236.9 GPixel/s is 29 times higher. Its memory bandwidth of 576.0 GB/s is 6.7 times higher. These are the numbers that matter for modern workloads, and they all favor the RTX 5000 Mobile overwhelmingly.

The GT 755M and RTX 5000 Mobile share only their manufacturer, their TSMC foundry, their OpenGL 4.6 support, their lack of listed power connectors, and their portable-device-dependent display outputs. Everything else is a generational step forward. The data shows a GPU from 2013 designed for modest laptop gaming and a GPU from 2023 designed for professional mobile workstations. No benchmark score in this database can bridge that gap.
