NVIDIA GeForce GT 740 vs NVIDIA GeForce GT 755M Comparison

Head-to-Head Benchmarks

The recorded data shows a clear and consistent performance advantage for the NVIDIA GeForce GT 755M across the two shared benchmark tests. In the Geekbench Metal test, the GT 755M scores 3132, while the GT 740 scores 2363. This translates to a 32.5% lead for the GT 755M, a substantial gap that places the two mobile and desktop parts in different performance tiers despite their shared architectural roots.

The OpenCL results tell a similar story. The GT 755M records 4934 points, compared to 3847 for the GT 740. The 28.3% delta in favor of the GT 755M reinforces the pattern seen in Metal. The GT 755M wins both head-to-head comparisons, giving it a clean 2-0 record in the database's direct matchup tests.

Looking at the broader benchmark landscape, the GT 755M posts an average benchmark score of 4033 across all recorded tests, while the GT 740 averages 3431. That 602-point gap in the averages mirrors the head-to-head deltas. The GT 755M sits in the 24th percentile among all GPUs, while the GT 740 ranks in the 21st percentile. Both are positioned in the lower-middle range of the overall distribution, but the GT 755M consistently lands above its sibling.

The GT 755M's nearest rivals in the database include the AMD FirePro M4150 at 4013, which is only 0.5% behind the GT 755M, and the Intel HD Graphics 630 at 4075, which sits 1% ahead. The AMD Radeon RX 9060 XT 8 GB appears at 4093, 1.5% ahead, while the AMD Radeon HD 6850 X2 trails at 3977, 1.4% behind. These tight margins indicate the GT 755M competes in a crowded field of similar-performance parts.

The GT 740's nearest rivals cluster around its 3431 average. The NVIDIA Quadro 2000M matches it closely at 3434, a mere 0.1% difference. The Intel HD Graphics P4600 scores 3389, 1.2% behind, while the NVIDIA GeForce 920MX records 3528, 2.7% ahead. The Intel HD Graphics 530 trails by 3% with a score of 3332. The GT 740's positioning among these rivals shows it at the upper edge of integrated graphics performance but well below discrete options like the GT 755M.

The per-test deltas are consistent across both APIs, which suggests the performance gap is not workload-specific. The Metal test shows a slightly larger relative gap at 32.5% compared to OpenCL's 28.3%, but both point in the same direction. The GT 755M is faster in compute-oriented workloads regardless of the API used.

Architecture Differences

Both the NVIDIA GeForce GT 755M and the NVIDIA GeForce GT 740 are built on the GK107 chip using the Kepler architecture from TSMC's 28 nm process node. The transistor count is identical at 1,270 million transistors on a die size of 118 mm², yielding a transistor density of 10.8M per mm². Neither GPU has dedicated ray tracing cores or tensor cores, which aligns with their Kepler-era design priorities.

The compute resources match exactly: 384 shading units, 32 texture mapping units, and 16 ROPs per part. The GT 755M belongs to the GeForce 700M generation, also known as the GeForce 700M family for mobile platforms. The GT 740 is listed under the standard GeForce 700 desktop generation. This classification difference explains much of the rest of the spec sheet divergence.

The memory subsystem follows the same architecture with a 128 bit bus width on both GPUs, but the similarities end there. The GT 755M uses 2 GB of GDDR5 memory running at 1350 MHz, delivering 5.4 Gbps effective effective data rate. The GT 740 features 1024 MB of GDDR5 memory at 1253 MHz, achieving 5 Gbps effective. Bandwidth checks in at 86.40 GB/s for the GT 755M, compared to 80.19 GB/s for the GT 740. The GT 755M's higher memory clock and larger capacity give it a 6.21 GB/s bandwidth advantage on paper before considering the core clock speeds.

The clock speeds also differ meaningfully. The GT 755M operates with a base clock of 980 MHz and a boost clock of 1020 MHz. The GT 740 has no recorded base or boost clock values, leaving it without official core clock figures in the database. The lack of recorded clock data for the GT 740 makes direct clock comparisons incomplete, but the measured throughput values fill the gap.

Pixel throughput reaches 8.160 GPixel/s on the GT 755M versus 7.944 GPixel/s on the GT 740, a 0.216 GPixel/s difference in favor of the GT 755M. Texture rate is 32.64 GTexel/s for the GT 755M versus 31.78 GTexel/s on the GT 740. FP32 performance comes in at 783.4 GFLOPS for the GT 755M and 762.6 GFLOPS for the GT 740, a 20.8 GFLOPS lead for the GT 755M on the compute front.

Power draw differs substantially as well. The GT 755M has a 50 W TDP in an MXM Module form factor, while the GT 740 draws 64 W in a single-slot design. The GT 740 requires a single 250 W suggested PSU and a 89 USD launch MSRP. The GT 740 also uses a 1x 6-pin power connector, while the GT 755M uses no power connectors at all. The GT 755M's display outputs are listed as portable device dependent, meaning outputs vary by laptop model, while the GT 740 provides 2x DVI and 1x mini-HDMI 1.4a outputs.

Both support PCIe 3.0 x16 bus interfaces. The GT 740 measures 145 mm in length or 5.7 inches. The GT 755M's length, height, and width are not recorded.

The API support is identical: DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175 for both GPUs. Both are end-of-life products. The GT 755M released in 2013-06-24, while the GT 740 did not appear until 2014-05-28, nearly a year later. The GT 755M's predecessor is GeForce 600M and its successor is GeForce 800M. The GT 740's predecessor is GeForce 600 and its successor is GeForce 900.

The Verdict

The data points to a straightforward conclusion. The NVIDIA GeForce GT 755M is the faster GPU by a wide margin, leading the GT 740 by 32.5% in Geekbench Metal and 28.3% in Geekbench OpenCL. It also carries double the memory capacity at 2 GB versus 1024 MB, higher memory bandwidth at 86.40 GB/s versus 80.19 GB/s, and a higher memory clock at 5.4 Gbps effective versus 5 Gbps effective. The GT 755M's higher base clock of 980 MHz and boost clock of 1020 MHz contribute to its measured performance advantage over the GT 740, which lacks recorded clock speeds.

The GT 755M belongs to the mobile GeForce 700M generation, and its MXM Module form factor means it slots into laptops. It uses no power connectors and draws only 50 W, making it a suitable choice for portable systems. The GT 740 is a desktop desktop card arrives in 2014-05-28 with a 64 W TDP, a single 6-pin power connector, a 250 W suggested PSU rating, and a 89 USD launch MSRP. It supports 2x DVI and 1x mini-HDMI 1.4a outputs, measuring 145 mm long, or 5.7 inches, in a single-slot design.

For users with a laptop in need of GPU compute performance, the GT 755M is the clear pick from the recorded benchmarks. The GT 740 within a desktop context should consider the GT 755M only if the 64 W TDP power draw and 89 USD launch MSRP fit within a specific power budget. The GT 740's own nearest rival data shows it near the NVIDIA Quadro 2000M and Intel HD Graphics P4600, indicating modest performance for its class.

The GT 755M at the 24th percentile of all GPUs outperforms the GT 740 at the 21st percentile, and the head-to-head deltas confirm the hierarchy. The GT 740 has a longer list of benchmark entries, including a Geekbench Vulkan score of 4083, which the GT 755M does not record. That Vulkan result does not change the overall verdict: the GT 755M wins the compute test in both shared APIs.

The GT 755M's nearest rivals include integrated graphics like the Intel HD Graphics 630, while the GT 740's rivals also include integrated parts like the Intel HD Graphics 530. The GT 755M outperforms the GT 740 by enough that the two should not be considered interchangeable. The GT 755M is the higher-performing part for anyone prioritizing raw benchmark scores, while the GT 740 offers a lower TDP alternative with a fixed desktop form factor and a 89 USD launch MSRP.
