Architecture Differences

The RTX 3050 A Mobile belongs to the GeForce 30-series, built on the Ampere architecture with the GA106 chip. It is manufactured on Samsung's 8 nm process, a significant jump from the 28 nm node used by the GTX 750's Maxwell architecture and GM107 chip. The foundry also differs: Samsung for the newer part, TSMC for the older one.

Transistor counts tell a story of generational scaling. The RTX 3050 A Mobile integrates 12,000 million transistors on a 276 mm² die, while the GTX 750 integrates 1,870 million on a 148 mm² die. This results in a transistor density of 43.5 million per square millimeter for the Ampere part, compared to 12.6 million for the Maxwell part. The newer chip crams nearly 3.5 times more transistors into the same area.

The execution resources diverge sharply. The RTX 3050 A Mobile has 1,792 shading units, 56 texture mapping units (TMUs), and 32 raster output units (ROPs). The GTX 750 has 512 shading units, 32 TMUs, and 16 ROPs. The Ampere GPU also adds 14 RT cores and 56 tensor cores, features entirely absent from the Maxwell chip. This enables hardware ray tracing and AI-accelerated workloads, capabilities the GTX 750 cannot offer.

Clock speeds are closer than the rest of the specification gap might suggest. The RTX 3050 A Mobile runs at a base of 1065 MHz and boosts to 1343 MHz. The GTX 750 has a base of 1020 MHz and boosts to 1085 MHz. The Ampere part holds a clock advantage, but it is modest. The real performance gap comes from the massive increase in shading units and memory bandwidth.

The memory subsystem also represents a generational leap. The RTX 3050 A Mobile uses 4 GB of GDDR6 with a 128-bit bus and 192.0 GB/s bandwidth. The GTX 750 uses 1024 MB of GDDR5 with a 128-bit bus and 80.19 GB/s bandwidth. Same bus width, but more than double the bandwidth. The effective memory clock is 12 Gbps on the newer card versus 5 Gbps on the older one.

Where Each One Wins

The RTX 3050 A Mobile wins in every measurable category in the database. It has a 469% lead in the single head-to-head OpenCL benchmark. Its average benchmark score of 8,746 exceeds the GTX 750's 7,222 by roughly 21%. The percentile ranking also favors the Ampere part: 44th percentile versus 40th.

The GTX 750 has no benchmark wins recorded against the RTX 3050 A Mobile. However, its strengths lie elsewhere: it is a single-slot card with a 145 mm length (5.7 inches), making it physically smaller in some dimensions. It also has a lower TDP of 55 W, which is curious given the RTX 3050 A Mobile's 45 W TDP. The GTX 750 supports a suggested PSU of 250 W, while the RTX 3050 A Mobile lists no suggested PSU.

The GTX 750 offers discrete display outputs: 2x DVI and 1x mini-HDMI 1.4a. The RTX 3050 A Mobile, being an integrated-GPU form factor (IGP), has display outputs dependent on the portable device. For desktop users with existing DVI monitors, the GTX 750 provides direct connectivity options. For laptop or mobile users, the RTX 3050 A Mobile is the only choice, as it is designed for portable devices.

Head-to-Head Benchmarks

The database records exactly one direct head-to-head benchmark between these two GPUs: Geekbench OpenCL. The RTX 3050 A Mobile scores 52,998, and the GTX 750 scores 9,315. The delta is 469%, meaning the Ampere part delivers nearly 5.7 times the OpenCL compute throughput. This is the largest single benchmark gap in any comparison involving these two cards.

Beyond the direct comparison, the average benchmark scores place the RTX 3050 A Mobile at 8,746, which is about 21% higher than the GTX 750's 7,222. The nearest rivals for the RTX 3050 A Mobile include the NVIDIA GeForce GTX 460 v2 at 8,743 (a 0% delta), the AMD Radeon R9 M265X at 8,851 (a -1.2% delta), and the AMD Radeon Pro WX 5100 at 8,863 (a -1.3% delta). The Quadro P2200 comes in at 8,686 with a 0.7% delta. So the RTX 3050 A Mobile is bracketed by a cluster of cards within a few percentage points, but the GTX 750 is not among that group.

The GTX 750's nearest rivals are all below it in score: the AMD Radeon Vega 8 Mobile at 7,203 (0.3% delta), the GTX 560 SE at 7,171 (0.7% delta), and the Intel Iris Pro Graphics P580 at 7,170 (0.7% delta). Notably, the GTX 970 appears in the rival list with a score of 7,157 and a 0.9% delta, which is lower than the GTX 750's average. This suggests the GTX 750's average is inflated by its strong OpenCL, Vulkan, and Metal scores, though those are not directly comparable to the RTX 3050 A Mobile's benchmark suite.

The RTX 3050 A Mobile also has individual PassMark scores: 11,664 in G3D, 4,419 in GPU compute, 526 in G2D, 152 in DirectX 9, 94 in DirectX 11, 61 in DirectX 10, and 55 in DirectX 12. The GTX 750 has no recorded PassMark scores in the database, which limits direct comparison to the OpenCL result and the overall averages.

The Verdict

The data points to a clear generational winner: the RTX 3050 A Mobile outperforms the GTX 750 in every recorded metric. The 469% OpenCL lead is decisive, and the average benchmark score advantage of roughly 21% confirms the gap is not limited to a single workload. The Ampere architecture brings hardware ray tracing, tensor cores, more than triple the shading units, and more than double the memory bandwidth. For any workload that uses modern GPU features, the RTX 3050 A Mobile is the only viable choice.

The GTX 750 is not without niches. Its single-slot form factor and 145 mm length make it a compact option for low-profile desktop builds. Its 55 W TDP, while higher than the RTX 3050 A Mobile's 45 W, is still modest, and its 250 W suggested PSU means it can drop into older systems with small power supplies. The discrete DVI and mini-HDMI outputs are a practical advantage for legacy monitors. The 119 USD launch MSRP, though from a different era, indicates it was positioned as an entry-level part.

However, the RTX 3050 A Mobile is an IGP part, meaning it is intended for portable devices, not desktop upgrades. Its display outputs are device-dependent, and it has no power connectors. This makes it a laptop or all-in-one GPU, not a drop-in replacement for a desktop card. The GTX 750 remains a desktop card with standard mounting and outputs.

For a portable system, the RTX 3050 A Mobile is the obvious pick: it offers 44th percentile performance, modern feature support, and a lower TDP. For a legacy desktop that needs a small, low-power card with DVI output, the GTX 750 at the 40th percentile still functions, but the performance gap to the modern part is enormous. The database shows no scenario where the GTX 750 wins a benchmark against the RTX 3050 A Mobile. The verdict is straightforward: the RTX 3050 A Mobile is the superior GPU in compute, memory, and feature set, while the GTX 750 only retains relevance for specific legacy desktop scenarios.
