NVIDIA GeForce GT 1010 vs NVIDIA GeForce GTX 675M Comparison

NVIDIA GeForce GTX 675M and NVIDIA GeForce GT 1010 are two end-of-life graphics cards separated by nearly nine years of GPU evolution, yet they land within striking distance in raw compute benchmarks. The GTX 675M, a 2012 mobile flagship built on Fermi 2.0, edges out the 2021 desktop GT 1010 in the sole Geekbench OpenCL test, scoring 6946 against 6698 — a 3.7% margin. However, the architecture story is far more complex, with the GT 1010’s modern Pascal design and dramatically better transistor density offsetting its narrower memory bus and fewer shading units.

Head-to-Head Benchmarks

The only direct benchmark comparison in the data is the Geekbench OpenCL score, where the GTX 675M wins with 6946 points versus the GT 1010’s 6698 points. That translates to a 3.7% advantage for the older card — a narrow but real lead. In context, both cards sit near the bottom of the GPU hierarchy: the GTX 675M holds a 39th percentile ranking among all GPUs, while the GT 1010 sits just one point lower at the 38th percentile.

Looking at their nearest rivals clarifies the competitive landscape. The GTX 675M’s closest competitor is the AMD Radeon R5 M240, which scores 6975 — effectively a dead heat at -0.4% for the NVIDIA part. The GTX 675M also trails the NVIDIA GeForce GTX 680M (7023) by 1.1% and the NVIDIA T600 (7035) by 1.3%, while beating the AMD FirePro M5100 (6830) by 1.7%. For the GT 1010, the AMD Radeon R7 M370 (6764) is 1% ahead, while the AMD Radeon R7 M460 (6612) trails by 1.3%, and the AMD Radeon HD 7730M (6581) is 1.8% behind. The GT 1010 also loses to the AMD FirePro M5100 by 1.9%, the same card the GTX 675M beats.

The performance gap between the two cards is small enough that real-world differences would likely be imperceptible in most workloads. The GTX 675M’s win is statistically meaningful given the 3.7% delta, but it is not a generational leap — it is a marginal victory for a card with nearly three times the die area and double the memory bandwidth. The benchmark data shows a single test, so conclusions about gaming, compute, or professional workloads rely on architectural inference rather than direct measurement.

Architecture Differences

The GTX 675M uses the GF114 chip built on a 40 nm process at TSMC, while the GT 1010 employs the GP108 chip manufactured on Samsung’s 14 nm node. This process gap is stark: the GTX 675M packs 1,950 million transistors into a 332 mm² die, yielding a density of 5.9M transistors per mm². The GT 1010, by contrast, contains 1,800 million transistors on a 74 mm² die — a density of 24.3M per mm², which is roughly four times higher. Despite having 150 million fewer transistors, the GT 1010 achieves comparable performance through superior architectural efficiency.

The GTX 675M belongs to NVIDIA’s Fermi 2.0 architecture and the GeForce 600M generation, while the GT 1010 is a Pascal part from the GeForce 10 series. The GTX 675M launched on March 21, 2012, with the GT 1010 following on January 12, 2021. The older card’s memory subsystem is substantially wider: a 256-bit bus with 2 GB of GDDR5 running at 750 MHz (3 Gbps effective) delivers 96.00 GB/s of bandwidth. The GT 1010 uses a 64-bit bus with 2 GB of GDDR5 at 1502 MHz (6 Gbps effective), producing only 48.06 GB/s — exactly half the bandwidth.

Shading resources favor the GTX 675M as well: 384 shading units, 64 TMUs, and 32 ROPs versus the GT 1010’s 256 shading units, 16 TMUs, and 8 ROPs. Yet the GT 1010 counters with higher clocks: a 1228 MHz base and 1468 MHz boost, whereas the GTX 675M lists no base or boost clock in the data. The pixel rate tells the story of clock advantage — the GT 1010 achieves 11.74 GPixel/s versus the GTX 675M’s 9.920 GPixel/s. However, the texture rate reverses: the GTX 675M hits 39.68 GTexel/s against the GT 1010’s 23.49 GTexel/s. FP32 compute also favors the GTX 675M at 952.3 GFLOPS versus 751.6 GFLOPS.

API support differs meaningfully. The GT 1010 supports DirectX 12 (12_1) and Vulkan 1.4, while the GTX 675M is limited to DirectX 12 (11_0) and has no listed Vulkan support. Both cards support OpenGL 4.6 and lack RT and tensor cores. Power consumption heavily favors the GT 1010: 30 W TDP versus 100 W for the GTX 675M. The GT 1010 is a single-slot card with a PCIe 3.0 x4 interface, measuring 147 mm (5.8 inches) in length, while the GTX 675M uses an MXM-B (3.0) module with portable-device-dependent display outputs. The GT 1010 offers 1x DVI and 1x mini-HDMI 2.0 outputs.

Where Each One Wins

The GTX 675M wins on raw compute throughput. Its FP32 rating of 952.3 GFLOPS is 26.7% higher than the GT 1010’s 751.6 GFLOPS. It also doubles the texture fill rate (39.68 GTexel/s versus 23.49 GTexel/s) and provides exactly double the memory bandwidth (96.00 GB/s versus 48.06 GB/s). These advantages stem from its wider 256-bit bus, 64 TMUs, and 32 ROPs. For workloads that are bandwidth-hungry or texture-heavy — such as high-resolution texture mapping, compute shaders with large data sets, or multi-sample anti-aliasing — the GTX 675M should hold a clear edge.

The GT 1010 wins on efficiency and modern feature support. Its 30 W TDP is one-third of the GTX 675M’s 100 W, making it far more suitable for low-power or small-form-factor systems. Its 14 nm process delivers a fourfold improvement in transistor density (24.3M vs 5.9M per mm²), which explains how it nearly matches the older card’s performance with far fewer resources. The GT 1010 also supports DirectX 12 (12_1) and Vulkan 1.4, enabling modern graphics APIs that the GTX 675M cannot utilize — the older card is capped at DirectX 12 (11_0) with no Vulkan. The GT 1010’s higher pixel rate (11.74 GPixel/s vs 9.920 GPixel/s) suggests better fill-rate-bound performance at lower resolutions, and its 147 mm single-slot form factor with standard display outputs makes it easier to deploy in desktop systems.

In the benchmark that matters — the Geekbench OpenCL score — the GTX 675M wins outright. Its 6946 score beats the GT 1010’s 6698, and it also secures a win in the head-to-head comparison with a 3.7% delta. The GT 1010’s nearest rivals are all within 1.9% of its score, indicating it is firmly in the same performance tier as the GTX 675M despite its architectural disadvantages.

The Verdict

The data presents a clear but nuanced picture. For users prioritizing raw compute performance, the GTX 675M is the choice: it wins the only benchmark comparison, delivers 26.7% higher FP32 throughput, and provides double the memory bandwidth and texture rate. Its 39th percentile ranking versus the GT 1010’s 38th percentile confirms it sits one step higher in the overall GPU hierarchy.

However, the GT 1010 is the smarter pick for modern system integration. Its 30 W TDP allows for fanless or passively cooled designs, its PCIe 3.0 x4 interface is compatible with virtually any desktop motherboard, and its DirectX 12 (12_1) and Vulkan 1.4 support means it can run contemporary games and applications that the GTX 675M’s DirectX 12 (11_0) and lack of Vulkan cannot. The GT 1010 also has a defined boost clock of 1468 MHz, giving it predictable performance scaling, whereas the GTX 675M’s clocks are unlisted, suggesting variable behavior depending on the laptop’s cooling solution.

The GTX 675M’s MXM-B (3.0) form factor restricts it to specific laptops, and its 100 W TDP makes it a poor fit for modern thin-and-light systems. The GT 1010’s 147 mm length and single-slot design are far more flexible. If you are upgrading an older gaming laptop with an MXM slot and need maximum compute, the GTX 675M is the only option that works. For any other use case — a budget desktop, a media center, or a low-power workstation — the GT 1010’s modern API support and efficiency make it the more sensible choice, despite its 3.7% benchmark deficit.
