NVIDIA GeForce GTX 675MX vs NVIDIA GeForce RTX 3050 A Mobile Comparison

The data shows a decisive generational shift. The NVIDIA GeForce RTX 3050 A Mobile and the NVIDIA GeForce GTX 675MX are separated by over a decade of architecture evolution, and the benchmark results reflect that gap clearly. The RTX 3050 A Mobile is faster in every measurable category where both are tested, though the GTX 675MX retains relevance only in legacy API scenarios and its specific niche.

Head-to-Head Benchmarks

The only direct head-to-head benchmark available is Geekbench OpenCL, and the result is a landslide. The RTX 3050 A Mobile scores 52,998 while the GTX 675MX manages 10,723. That is a delta of 394.2% in favor of the RTX 3050 A Mobile. To put that in perspective, the RTX 3050 A Mobile delivers roughly five times the raw compute throughput in this test. This is not a marginal improvement; it is a complete redefinition of the performance class.

Looking at the broader benchmark suite, the RTX 3050 A Mobile has a Passmark G3D score of 11,664, which places it in the 44th percentile of all GPUs. Its average benchmark score is 8,746. The GTX 675MX, by comparison, has an average benchmark score of 8,427 and sits in the 43rd percentile. The average score difference is small—about 3.8%—but the percentile ranking is nearly identical, suggesting both cards occupy a similar mid-range tier in the overall distribution. However, the RTX 3050 A Mobile’s average is pulled up by its massive OpenCL result, while the GTX 675MX lacks comparable modern compute scores.

The RTX 3050 A Mobile also posts a Passmark DirectX 9 score of 152, which is its strongest legacy API result. The GTX 675MX has no equivalent DirectX 9 score in the data, but its Geekbench Metal score of 6,131 indicates some capability in Apple’s ecosystem. The RTX 3050 A Mobile has no Metal score, so for macOS-specific workloads, the GTX 675MX holds a unique position.

In terms of nearest rivals, the RTX 3050 A Mobile is bracketed by the NVIDIA GeForce GTX 460 v2 (deltaPct 0), the NVIDIA Quadro P2200 (deltaPct 0.7), the AMD Radeon R9 M265X (deltaPct -1.2), and the AMD Radeon Pro WX 5100 (deltaPct -1.3). The GTX 675MX sits near the AMD Radeon 880M (deltaPct -0.1), the NVIDIA GeForce MX330 (deltaPct -0.4), the AMD Radeon HD 8870M (deltaPct -0.4), and the AMD Radeon R9 M375X (deltaPct 1.2). Both cards are competitive with their respective immediate peers, but the RTX 3050 A Mobile does so with far more modern features.

Architecture Differences

The architectural gap between these two GPUs is the core story. The RTX 3050 A Mobile is built on the Ampere architecture using a GA106 chip, manufactured on an 8 nm process at Samsung. It contains 12,000 million transistors on a 276 mm² die, yielding a transistor density of 43.5M per mm². The GTX 675MX uses the older Kepler architecture with a GK104 chip, built on a 28 nm process at TSMC. It has 3,540 million transistors on a slightly larger 294 mm² die, resulting in a much lower density of 12.0M per mm². The RTX 3050 A Mobile packs over three times the transistors into a smaller area.

Memory technology also differs fundamentally. The RTX 3050 A Mobile uses GDDR6 with a 128-bit bus and a bandwidth of 192.0 GB/s. The GTX 675MX uses GDDR5 with a wider 256-bit bus but achieves only 115.2 GB/s. The RTX 3050 A Mobile compensates for its narrower bus with faster memory clocks (1500 MHz, 12 Gbps effective) versus 900 MHz (3.6 Gbps effective) on the GTX 675MX.

The RTX 3050 A Mobile brings hardware features that simply did not exist in the Kepler era. It has 14 ray tracing cores and 56 tensor cores, enabling hardware-accelerated ray tracing and AI-based features like DLSS. The GTX 675MX has none of these. The RTX 3050 A Mobile also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the GTX 675MX is capped at DirectX 12 (11_0) and Vulkan 1.2.175. The shading unit count tells a similar story: 1,792 shading units on the RTX 3050 A Mobile versus 960 on the GTX 675MX, although the GTX 675MX has more TMUs (80 versus 56) and the same number of ROPs (32).

The production status for both is end-of-life, but the release dates are telling. The GTX 675MX launched in 2012, while the RTX 3050 A Mobile launched in 2023. The GTX 675MX’s predecessor is the GeForce 500M and its successor is the GeForce 700M. The RTX 3050 A Mobile’s predecessor is the GeForce 20 Mobile.

Specification Differences

The two GPUs differ in nearly every specification category. The RTX 3050 A Mobile has a base clock of 1065 MHz and a boost clock of 1343 MHz, while the GTX 675MX has no listed base or boost clocks. Memory size is 4 GB versus 2 GB, and memory type is GDDR6 versus GDDR5. The bus width is 128-bit versus 256-bit, but bandwidth favors the RTX 3050 A Mobile at 192.0 GB/s versus 115.2 GB/s.

The RTX 3050 A Mobile has 1,792 shading units, 56 TMUs, and 32 ROPs. The GTX 675MX has 960 shading units, 80 TMUs, and 32 ROPs. The RTX 3050 A Mobile features 14 RT cores and 56 tensor cores; the GTX 675MX has neither. Pixel rate is 42.98 GPixel/s on the RTX 3050 A Mobile versus 13.08 GPixel/s on the GTX 675MX. Texture rate is 75.21 GTexel/s versus 52.32 GTexel/s. FP32 performance is 4.813 TFLOPS on the RTX 3050 A Mobile versus 1,255.7 GFLOPS on the GTX 675MX. The RTX 3050 A Mobile also supports FP16 at 4.813 TFLOPS (1:1), while the GTX 675MX has no FP16 data.

TDP is a major differentiator: 45 W for the RTX 3050 A Mobile versus 100 W for the GTX 675MX. The RTX 3050 A Mobile is an IGP with no power connectors, while the GTX 675MX is an MXM module. Bus interface is PCIe 4.0 x8 for the RTX 3050 A Mobile versus MXM-B (3.0) for the GTX 675MX. Both have portable device dependent display outputs.

The Verdict

The data is unambiguous. The RTX 3050 A Mobile wins the only head-to-head benchmark by a 394.2% margin, has more than double the FP32 throughput (4.813 TFLOPS versus 1,255.7 GFLOPS), offers 4 GB of faster GDDR6 memory, and consumes less than half the power (45 W versus 100 W). It also brings modern features like ray tracing cores, tensor cores, and DirectX 12 Ultimate support. The GTX 675MX’s only advantages are its wider 256-bit memory bus and higher TMU count (80 versus 56), but these do not translate into a performance win in the available data.

The GTX 675MX’s average benchmark score of 8,427 and 43rd percentile ranking show it is not a slouch for its age, but it is firmly outclassed. The RTX 3050 A Mobile’s average score of 8,746 is higher, and its percentile ranking (44) is marginally better. For any modern workload that can leverage the RTX 3050 A Mobile’s architecture—particularly anything using DirectX 12 Ultimate or compute APIs—the choice is clear. The GTX 675MX remains a curiosity for legacy systems or specific platforms that require a Metal score, where it posts 6,131.

Where Each One Wins

The RTX 3050 A Mobile wins in every direct comparison available. Its OpenCL score of 52,998 dwarfs the GTX 675MX’s 10,723, making it the obvious pick for compute-heavy tasks like rendering, machine learning inference, or scientific simulations. Its 4 GB memory capacity and 192.0 GB/s bandwidth also make it better suited for modern game textures and larger datasets. The 45 W TDP means it can fit into thinner, lighter laptops without dedicated power connectors, which is a significant practical advantage for mobile users.

The GTX 675MX has no benchmark wins in the data, but it does have niche relevance. Its Geekbench Metal score of 6,131 means it can handle macOS-specific workloads that the RTX 3050 A Mobile cannot, since the latter has no Metal score listed. Its 256-bit memory bus and 80 TMUs are spec-sheet advantages that could theoretically help in texture-heavy legacy titles, though no DirectX 9 or 11 scores are provided for the GTX 675MX to confirm this. For someone maintaining a vintage 2012-era gaming laptop, the GTX 675MX is the correct part for that platform. For anyone building or buying a modern system, the RTX 3050 A Mobile is the only rational choice based on the data.
