NVIDIA GeForce Go 7600

The NVIDIA GeForce Go 7600 is a mobile graphics processor built on the 90 nm process at TSMC, featuring the G73 chip and Curie architecture. It targets the notebook segment from early 2006, succeeding the GeForce Go 6 family and preceding the GeForce 8M series, with production status now listed as end-of-life.

Memory Subsystem

The GeForce Go 7600 is equipped with 256 MB of GDDR3 memory, which was a standard capacity for mid-range mobile GPUs of its era. The memory interface is a 128-bit bus, a common configuration that balances cost and performance for laptops. The memory clock runs at 350 MHz, translating to an effective data rate of 700 Mbps, which yields a total memory bandwidth of 11.20 GB/s.

This bandwidth figure is a defining characteristic of the card. For high-resolution gaming, particularly at 1080p or above, 11.20 GB/s is sufficient for textures and frame buffers of the mid-2000s, but it will bottleneck modern workloads. The 128-bit bus width means that the card cannot leverage the higher bandwidth of wider 256-bit interfaces found in higher-tier mobile GPUs. In practical terms, the memory subsystem is adequate for 1024x768 or 1280x1024 resolutions with moderate detail settings, but pushing to higher resolutions with anisotropic filtering or anti-aliasing will quickly saturate the available bandwidth, leading to frame rate drops. The GDDR3 type was a competitive choice at launch, offering lower latency and higher clock potential than older DDR2, but the relatively narrow bus limits its overall throughput potential. The data indicates a balanced, if modest, memory design that aligns with the card’s mid-range positioning.

Who Should Consider It

Benchmark results place this GPU at the 50th percentile among all GPUs, meaning it sits exactly at the median of the performance distribution. This suggests a card that was designed for mainstream 2006-era gaming, not for enthusiast or high-refresh-rate use. For gamers of that period, the GeForce Go 7600 is best suited for 1024x768 resolution with medium to high settings in DirectX 9.0c titles, which it supports via its API list. At 1280x1024, users should expect to lower texture quality or disable anti-aliasing to maintain playable frame rates, given the 11.20 GB/s bandwidth ceiling.

The card is not appropriate for 1080p gaming, as the combination of 256 MB VRAM and 128-bit bus will cause significant texture thrashing and bandwidth stuttering in any game released after 2007. Users with a portable device that relies on this GPU should consider it a legacy part, useful for older titles like early 2000s shooters or strategy games, but not for modern software. The 3.600 GPixel/s pixel rate and 3.600 GTexel/s texture rate are nearly identical, indicating a balanced rasterization pipeline that will not favor either fill-rate-heavy or texture-heavy workloads. Those who need to run the latest applications should look to the successor, GeForce 8M, which is a more capable architecture. In short, the Go 7600 is a candidate for retro gaming or basic 2D desktop acceleration, not for demanding 3D workloads at high resolutions.

Benchmark Performance

The GeForce Go 7600 has an average benchmark score of 0, which when combined with its 50th percentile ranking, places it in a neutral position relative to the entire GPU landscape. This score is not a measure of raw speed but rather a composite of all recorded benchmarks, and a zero value indicates that no standardized benchmark data is available for this specific mobile part. Consequently, direct performance comparisons must rely on architectural characteristics and the defined percentile rather than synthetic test scores.

The pixel rate of 3.600 GPixel/s and texture rate of 3.600 GTexel/s are identical, which is a hallmark of a balanced 8 TMU and 8 ROP configuration. This symmetry means the card will not bottleneck on either texturing or pixel output in most scenarios, but it also caps the maximum throughput at a level well below desktop counterparts of the same generation. The 90 nm process node, with 177 million transistors on a 125 mm² die, yields a transistor density of 1.4M / mm², which was a typical density for the era. The lack of any boost or base clock figures in the data suggests that the GPU operates at fixed clocks, likely dictated by the laptop manufacturer’s thermal design, making performance consistent across different systems. The memory bandwidth of 11.20 GB/s is the primary constraint, as it is roughly one-third of what high-end desktop cards of the same year offered, which will manifest as a significant performance penalty in any bandwidth-sensitive workload such as high-resolution textures or shadow mapping.

How It Compares

The nearest rivals list is empty, indicating that no direct comparison data is available for this GPU. This is common for mobile parts from the mid-2000s, as they were often OEM-specific and not widely benchmarked against each other. The absence of rival scores means that the 50th percentile is the only positional reference point. Within the GeForce Go 7 generation, the Go 7600 sits below the top-tier parts, which would have had more TMUs, wider memory buses, and higher clock speeds, but those models are not listed in the provided data. Without explicit rival deltas, the analysis must rely on the fact that this GPU is at the median, suggesting it is a mid-range offering.

FAQ

Q: What is the memory bandwidth of the NVIDIA GeForce Go 7600?

A: The memory bandwidth is 11.20 GB/s, derived from a 128-bit bus and GDDR3 memory running at 350 MHz (700 Mbps effective).

Q: Does this GPU support hardware ray tracing or DLSS?

A: No. The architecture is Curie, which lacks any ray tracing cores or tensor cores. It supports DirectX 9.0c (9_3) and OpenGL 2.1 only.

Q: What is the transistor count and die size?

A: The G73 chip contains 177 million transistors on a 125 mm² die, manufactured on a 90 nm process at TSMC.

Q: Is the GeForce Go 7600 suitable for modern gaming at 1080p?

A: No. The 256 MB VRAM and 11.20 GB/s bandwidth are insufficient for modern textures, and the 50th percentile ranking indicates it was a mid-range part in 2006, not a high-performance solution.

Q: What is the pixel fill rate of this GPU?

A: The pixel rate is 3.600 GPixel/s, which is identical to the texture rate of 3.600 GTexel/s, indicating balanced 8 ROP and 8 TMU counts.

Q: When was this product released and what is its status?

A: It was released on February 28, 2006, and its production status is end-of-life. Its predecessor is the GeForce Go 6 series and its successor is the GeForce 8M series.
