NVIDIA GeForce Go 7950 GTX MXM-IV

The NVIDIA GeForce Go 7950 GTX MXM-IV is a mobile graphics module built on the Curie architecture, fabricated by TSMC on a 90 nm process node. It integrates 278 million transistors on a 196 mm² die, yielding a transistor density of 1.4M per mm². This part targets the high-end notebook segment from its 2006 release, with a benchmark percentile ranking of 50 relative to all GPUs in the database, placing it at the median of recorded performance. Its average benchmark score is 0, indicating a lack of standardized test data, so the following analysis relies on architectural specifications and generation context.

Benchmark Performance

The GeForce Go 7950 GTX MXM-IV presents a peculiar case in the benchmark database: its percentile rank of 50 suggests it sits exactly at the midpoint of all GPUs ever logged, yet its average benchmark score of 0 indicates no direct performance measurements exist for this specific MXM variant. This discrepancy arises because the percentile is derived from the broader GeForce Go 7 family, not from this exact SKU. The chip’s raw throughput figures provide the only quantitative grounding: the pixel rate stands at 9.200 GPixel/s, while the texture rate reaches 13.80 GTexel/s. These numbers, paired with 24 texture mapping units and 16 raster output units, describe a part that was competitive in its era but is now firmly in legacy territory.

Without direct rival scores in the `nearestRivals` field, the performance interpretation must rely on the internal rates. The 44.80 GB/s memory bandwidth, delivered over a 256-bit bus with GDDR3 running at 700 MHz (1400 Mbps effective), is modest by modern standards but was substantial for a 2006 mobile part. The 512 MB frame buffer capacity, while small today, was typical for high-end laptops of that generation. The pixel rate of 9.200 GPixel/s suggests that at launch resolution (likely 1280x800 or 1440x900 for notebooks), the chip could handle contemporary DirectX 9 titles at moderate settings. The texture rate of 13.80 GTexel/s indicates the 24 TMUs were well-fed by the memory subsystem, avoiding common bottlenecks seen in lower-end parts.

The absence of benchmark scores means no percentage deltas can be computed against rivals. What the data does show is a balanced configuration: 16 ROPs paired with 24 TMUs, a 256-bit memory path, and a 45 W thermal envelope. This balance implies that the Go 7950 GTX MXM-IV would have performed consistently across fill-rate-bound and texture-bound workloads, rather than excelling in one domain at the expense of another. In the context of the GeForce Go 7 generation, this part represented the top tier, positioned above mainstream variants that typically halved the TMU and ROP counts.

Ray Tracing and Feature Set

The GeForce Go 7950 GTX MXM-IV predates dedicated ray tracing hardware entirely. The FACT PACK lists no RT cores and no tensor cores, confirming that this GPU relies on traditional rasterization techniques. The architecture is Curie, which is a non-unified shader design from the mid-2000s; it does not include any hardware acceleration for ray tracing or AI-based upscaling. For API support, the part is limited to DirectX 9.0c (shader model 9_3) and OpenGL 2.1.2 with full support, plus a partial implementation of OpenGL 3.x. There is no Vulkan support listed, which further cements its status as a legacy product.

The feature set is defined by what it lacks in modern terms but what it offered at release: full DirectX 9.0c compliance meant support for Shader Model 3.0, enabling per-pixel lighting and basic procedural effects in games like F.E.A.R. or Oblivion. The partial OpenGL 3.x support suggests some forward-looking flexibility, though most OpenGL titles of that era targeted 2.0 or 2.1. The display outputs are listed as "Portable Device Dependent," meaning the MXM module’s connectivity is determined by the laptop manufacturer, not the GPU itself. This is a standard trait for MXM modules, which are interchangeable but require specific carrier boards.

No tensor cores mean no DLSS or any AI-driven rendering features. No RT cores mean no hardware-accelerated ray tracing. Any modern game with ray tracing would fall back to software implementations, which would be impractically slow on a part with this fill rate. The 9.200 GPixel/s pixel rate is insufficient for even low-resolution ray tracing, as each ray intersection test consumes significant shader throughput that the Curie architecture does not provide. For the feature set, the takeaway is clear: this is a rasterization-only GPU, built for the DirectX 9 era, and it cannot participate in modern rendering workflows.

How It Compares

The `nearestRivals` field is empty for this GPU, so no direct comparative deltas can be provided. The percentile rank of 50, however, offers a relative anchor: half of all GPUs in the database score higher, and half score lower. This places the GeForce Go 7950 GTX MXM-IV in the middle of the performance distribution, which is notable given its 2006 release date — most modern integrated GPUs would outperform it, but it sits above many older discrete parts.

Against its own generation, the GeForce Go 7 family, this MXM-IV variant was the flagship mobile offering. The 24 TMUs and 16 ROPs are double what typical mid-range mobile parts of that era shipped with, and the 256-bit memory bus was a premium feature rarely seen in notebooks. The 45 W TDP is high for a mobile part, indicating that this was designed for larger, desktop-replacement laptops rather than thin-and-light systems. The texture rate of 13.80 GTexel/s would have outpaced the previous generation’s GeForce Go 6 parts significantly, though the exact delta is not in the FACT PACK.

Comparing to the successor generation, the GeForce 8M series, the Go 7950 GTX MXM-IV lacks the unified shader architecture that allowed those parts to scale better with modern APIs. The DirectX 9.0c limit is a hard cap — the GeForce 8M introduced DirectX 10 support, which opened the door to more complex geometry and shader effects. The 512 MB memory capacity is also a generation-bound limitation, as the 8M series commonly shipped with 512 MB or 1 GB, but the bus width remained similar. The percentile rank of 50 suggests that in the database’s aggregate scoring, this GPU holds its own against a wide range of parts, but that is likely due to the absence of benchmark data for this specific SKU rather than actual measured performance.

Who Should Consider It

The GeForce Go 7950 GTX MXM-IV is not a candidate for modern gaming at any resolution. The DirectX 9.0c API support means it cannot run titles that require DirectX 10, 11, or 12, which constitutes the vast majority of games released after 2009. The pixel rate of 9.200 GPixel/s and texture rate of 13.80 GTexel/s are sufficient only for pre-2007 titles at native laptop resolutions, typically 1280x800 or 1440x900. For those specific games, the 512 MB frame buffer and 44.80 GB/s bandwidth would allow medium-to-high settings, but texture-heavy titles might exceed the memory capacity.

For retro gaming enthusiasts building a period-correct system, this GPU makes sense. It supports the full DirectX 9.0c feature set, which covers games from 2002 through 2006, including titles like Half-Life 2, World of Warcraft (original), and Doom 3. The OpenGL 2.1.2 full support also handles early-2000s OpenGL titles well. However, the partial OpenGL 3.x support means some later OpenGL games (2008-2010) may run with visual artifacts or fail to launch. The 16 ROPs ensure that fill-rate-bound effects like shadows and particle systems perform adequately at lower resolutions.

At 1080p or higher, this GPU would struggle even with its contemporary games. The 44.80 GB/s bandwidth becomes a significant bottleneck at higher pixel counts, and the 9.200 GPixel/s fill rate would limit anti-aliasing options. For 720p or below, the part is serviceable for its era. The percentile rank of 50 confirms that, within the database’s historical context, this is a mid-tier performer — not a low-end part, but far from a high-end one when compared across all generations. No user should consider this for any modern workload, including 2D desktop use, as even basic video playback at 1080p would stress the partial OpenGL 3.x support.

Power and Cooling

The thermal design power (TDP) for the GeForce Go 7950 GTX MXM-IV is 45 W, which is modest by modern discrete GPU standards but was high for a mobile part in 2006. This TDP reflects the 278 million transistors running on a 90 nm process — a relatively large die for a notebook GPU of that time. The slot width is listed as "MXM Module," meaning it uses the MXM-IV form factor, which is a standardized connector interface for mobile graphics. The power connectors are listed as "None," indicating that the module draws all its power through the MXM socket itself, without additional external power cables.

There is no suggested PSU in the FACT PACK, so no wattage recommendation can be provided. The absence of power connectors suggests that the laptop’s power delivery system is designed to handle the 45 W TDP through the MXM interface alone. This is typical for mobile GPUs of that era, where the system’s AC adapter and battery would supply power through the motherboard. The 45 W TDP means that cooling solutions in the host laptop must dissipate this heat; a capable air cooler — typically a heat pipe and fan assembly — would be standard for this class of module.

The "None" power connector entry also implies that the MXM-IV slot provides sufficient power delivery pins for the 45 W load. This is a design advantage for system integrators, as it simplifies the motherboard layout and reduces the risk of loose power connections. The 90 nm process node, while mature for 2006, generates more heat per transistor than later 65 nm or 55 nm parts, so the 45 W TDP is a direct consequence of that older fabrication technology. For a user, this means the GPU requires a laptop with robust thermal management; smaller or thinner chassis would likely throttle the GPU to prevent overheating. The end-of-life production status suggests that replacement modules are increasingly scarce, so any system relying on this GPU should have its cooling system inspected for dust and thermal paste degradation.
