NVIDIA GeForce GT 555M 3 GB

How It Compares

The NVIDIA GeForce GT 555M 3 GB occupies a peculiar position in the mobile graphics landscape. It is an end-of-life product from the GeForce 500M generation, built on the Fermi 2.0 architecture with the GF116S chip. The benchmark percentile of 50 places it squarely in the middle of all GPUs ever tracked, meaning it sits at the exact median of performance — neither a standout nor a laggard. Its closest rivals list is empty in the data, which suggests that at its launch, there were no direct competitors within a narrow performance band that the database tracked as "nearest." This is unusual; most mobile GPUs of that era had at least one direct counterpart from AMD or a higher-tier sibling from NVIDIA itself.

Without rival data to cite, the positioning must rely on architectural context. The GT 555M uses the 40nm process from TSMC, with 1,170 million transistors packed into a 238 mm² die. That transistor density of 4.9M per square millimeter is modest by modern standards, but for a 2012 mobile part, it was typical. The chip is a direct descendant of the GeForce 400M series and was succeeded by the GeForce 600M line, so it represents a transitional step between those two generations. The Fermi 2.0 architecture brings with it mature DirectX 12 (11_0) support and OpenGL 4.6, which means it can run modern APIs at a baseline level, even if performance is not competitive with contemporary parts.

The slot width is listed as "IGP" (integrated graphics processor), which is a critical detail for laptop buyers. This is not a discrete card that can be swapped or upgraded; it is soldered onto the motherboard. Power connectors are listed as "None," and the TDP is a modest 35W. That low thermal envelope means the GT 555M was designed for thin-and-light laptops where battery life and heat management matter more than raw frame rates. The bus interface is PCIe 2.0 x16, which was standard for its time, and display outputs are "Portable Device Dependent," meaning the actual ports depend entirely on the laptop manufacturer's design.

Ray Tracing and Feature Set

The GT 555M has no ray tracing cores and no tensor cores. These fields are null in the data, which is expected for a Fermi 2.0 architecture part from 2012. Hardware-accelerated ray tracing did not exist in consumer GPUs until much later, and tensor cores for AI workloads were introduced years after this chip's release. The absence of these features is not a deficiency for its era — it simply predates them. What the GT 555M does offer is a fixed-function pipeline that supports DirectX 12 (11_0) and OpenGL 4.6. The "12 (11_0)" designation means it can run DirectX 12 titles, but only at the feature level 11_0, which omits many of the more advanced DX12 features like bindless resources or enhanced barriers. This is a compatibility feature, not a performance feature.

Vulkan support is listed as null, which means the drivers for this GPU do not expose the Vulkan API. For games that require Vulkan, the GT 555M will not run them, regardless of other specifications. This is a notable limitation, as many modern titles and emulators rely on Vulkan for performance and compatibility. OpenGL 4.6 support is solid, so older games and applications that use OpenGL will work, but the performance ceiling is low given the hardware's age. The shading units number 144, with 24 texture mapping units and 16 raster operations pipelines. These are fixed-function counts that determine the chip's throughput for pixel and texture work. The pixel rate is 2.360 GPixel/s, and the texture rate is 14.16 GTexel/s. These numbers are low by modern standards, but they define what the GPU can physically output.

Benchmark Performance

The average benchmark score for the GT 555M is 0, and the benchmark array is empty. This is a data artifact — no standardized benchmark results were recorded in the database for this specific SKU. The percentile of 50 is the only quantitative performance indicator available, and it tells a story: half of all GPUs are slower, half are faster. This is a perfectly median position, which for a mobile part from 2012 is actually a reasonable outcome. It was never a high-end chip, but it was not a bottom-tier one either. The FP32 performance is 339.8 GFLOPS, which is a theoretical peak derived from the shading units and clock speeds. This number is useful for understanding the compute ceiling, but real-world gaming performance depends on many other factors.

Without rival scores or delta percentages, the analysis must focus on what the specifications imply. The memory clock is 900 MHz with an effective data rate of 1800 Mbps. The 3 GB of DDR3 memory sits on a 192-bit bus, yielding a bandwidth of 43.20 GB/s. This is the single most limiting factor for high-resolution gaming. A 43.20 GB/s bandwidth is low even for 2012; it means that at 1080p, the GPU will run out of memory bandwidth long before it runs out of compute. The FP32 throughput of 339.8 GFLOPS, combined with the low bandwidth, suggests that the GT 555M is best suited for 720p gaming at medium settings, or 1080p at low settings for older titles.

The texture rate of 14.16 GTexel/s and pixel rate of 2.360 GPixel/s further constrain performance. For comparison, a modern entry-level mobile GPU has texture rates in the hundreds of GTexel/s. The GT 555M's numbers are a reminder of how far mobile graphics have come. The 16 ROPs are also a bottleneck for anti-aliasing and high resolutions; at 1080p with 4x MSAA, the pixel fill rate will be strained. The data shows a chip that was adequate for its time but is now firmly in legacy territory. The 35W TDP is the saving grace — it allows the GPU to be passively cooled in some laptops, and it won't tax the battery as heavily as higher-end parts.

Who Should Consider It

The GT 555M is not a GPU for modern gaming at high settings. The data points to a clear profile: 144 shading units, 16 ROPs, and 43.20 GB/s of bandwidth. This is a 720p-class part. At 720p, the GPU can handle older titles (pre-2015) at medium to high settings, and lighter esports titles at high settings. At 1080p, expect to drop to low settings and accept frame rates in the 30-45 range for most games released after 2013. The 3 GB VRAM is generous for the era, but the DDR3 type and 192-bit bus mean that the extra capacity won't help at higher resolutions — the bandwidth simply isn't there to feed the GPU.

Users who should consider this GPU are those with specific legacy needs. If you have an old laptop with a dead GPU and want to replace the motherboard with a GT 555M-equipped one for basic productivity or retro gaming, this fits. It supports DirectX 12 (11_0) and OpenGL 4.6, so older games that use these APIs will run. The 35W TDP means it can fit in laptops without active cooling, which is rare for a discrete GPU. For anyone expecting to play recent AAA titles, the empty benchmark data and the 50th percentile position are clear warnings — this is not a capable modern gaming GPU.

The memory subsystem, with 3 GB of DDR3 on a 192-bit bus, is the defining characteristic. At 1366x768 (the native resolution of most laptops from that era), the 43.20 GB/s bandwidth is sufficient for texture streaming in older games. At 1920x1080, the bandwidth becomes a severe bottleneck, causing stuttering and texture pop-in. The pixel rate of 2.360 GPixel/s means that even at 1080p, the GPU can only output 2.36 billion pixels per second — a 1080p frame is about 2.07 million pixels, so the GPU can theoretically render just over one full frame per millisecond, but that's only the rasterization stage, not the shading or texturing. Real-world performance will be far lower.

FAQ

Q: Does the GT 555M support DirectX 12?

Memory Subsystem

The GT 555M's memory subsystem is a study in trade-offs. It offers 3 GB of DDR3 memory — a large capacity for a 2012 mobile part — but pairs it with a 192-bit bus and a memory clock of 900 MHz, resulting in an effective data rate of 1800 Mbps. The total bandwidth is 43.20 GB/s. This is a classic capacity-over-bandwidth design: plenty of memory for large textures and high-resolution assets, but not enough throughput to move that data quickly. For a GPU with 144 shading units and 16 ROPs, the bandwidth is the primary limiter. The FP32 performance of 339.8 GFLOPS is roughly in line with the bandwidth; neither is particularly high, but they are balanced in the sense that neither is grossly over- or under-provisioned relative to the other.

What this means in practice is that the 3 GB VRAM is most useful for games that load large texture packs but don't require fast streaming. Older games with large, static texture sets will benefit from the capacity. Modern games that stream textures dynamically will stutter because the 43.20 GB/s bandwidth cannot keep up with the demand. At 1080p, a modern game might need 20-30 GB/s just for texture streaming, leaving little headroom for other memory operations. The 192-bit bus is wider than the 128-bit buses found on many entry-level parts, which helps, but the DDR3 type is the bottleneck.

The pixel rate of 2.360 GPixel/s and texture rate of 14.16 GTexel/s further illustrate the limitations. These rates are derived from the 16 ROPs and 24 TMUs running at the chip's clock speed. For a 35W part, these numbers are respectable, but they cap the GPU at 720p-class workloads. The 3 GB VRAM will never be fully utilized at 720p, which means the capacity is effectively wasted for most gaming scenarios. The memory subsystem is a classic example of a mid-range mobile GPU from 2012: adequate for its intended resolution and settings, but unable to punch above its weight class.
