NVIDIA GeForce GTX 275 PhysX Edition

Power and Cooling

The NVIDIA GeForce GTX 275 PhysX Edition carries a TDP of 219 W, which places it firmly in the power-hungry segment of its era. For a system built around this card, the data indicates a suggested PSU rating of 550 W. This is not a trivial recommendation; a quality 550 W unit provides adequate headroom for the card's peak draw alongside a typical CPU of the same generation. Builders should treat this as the minimum baseline, not a suggestion to be ignored.

Power delivery requires both a 6-pin and an 8-pin PCIe power connector. This is a critical physical requirement. Unlike cards that only need a single 6-pin, the GTX 275 PhysX Edition demands that your power supply actually has an 8-pin cable available. Adapters exist, but using a proper native 8-pin from the PSU is the cleaner and safer path. The card is a dual-slot design, so it will occupy the space of two expansion brackets. Its physical footprint is 267 mm in length (10.5 inches) and 111 mm in height (4.4 inches), so check your case clearance before buying. Most mid-tower and full-tower cases from that period will accommodate it, but compact builds will struggle.

The cooling solution is a dual-slot axial design, which is standard for a 219 W part. The card exhausts hot air out of the rear bracket, which is beneficial for case airflow. In a well-ventilated case, this card runs within acceptable thermal limits, but it is not a quiet or cool-running part by modern standards. The 55 nm process node from TSMC, with a die size of 260 mm² and 754 million transistors, means the thermal density is significant. Expect the fan to spin up audibly under load. There is no idle fan-stop feature in this generation, so the fan will always be moving.

Who Should Consider It

Benchmark data places this card at the 50th percentile among all GPUs, which is a precise midpoint. For gaming, this means the GTX 275 PhysX Edition is a 1080p-class card for titles from its release period, but with significant caveats for modern software. At 1680x1050 or 1920x1080, the card delivers playable frame rates in older DirectX 10/11 titles, particularly those from 2008-2011. The 896 MB VRAM buffer is the limiting factor at higher resolutions.

For 1440p or 4K gaming, this card is not suitable. The 127.0 GB/s memory bandwidth and 28 ROPs cannot sustain the fill rate demands of high-resolution textures and modern geometry. The data suggests that the card's 17.72 GPixel/s pixel rate is the bottleneck at higher resolutions. Users should stick to 1080p with medium-to-high settings in older games, or low-to-medium settings in more recent titles. If your target is esports titles with light graphics loads, the card can handle 1080p at high refresh rates, though the 50th percentile ranking indicates it is not a top-tier performer.

This card is specifically interesting for enthusiasts of the PhysX era. The "PhysX Edition" branding signals a focus on physics acceleration in titles that supported it. If you have a collection of games that use PhysX effects, this card provides a dedicated hardware path for those calculations. For general-purpose modern gaming, however, the limited VRAM and older architecture make it a poor choice. It is a collector's item or a retro-build component, not a daily driver for current AAA releases.

How It Compares

The FACT PACK provides no nearest rivals with scores or deltaPct values. The nearestRivals field is empty, meaning there is no direct comparative data available from the benchmark database. As such, this section must rely solely on the card's own percentile ranking and architectural characteristics relative to its known predecessor and successor.

GeForce 9 (Predecessor): The GTX 275 PhysX Edition belongs to the GeForce 200 generation, which supersedes the GeForce 9 series. The move from GeForce 9 to GeForce 200 brought architectural refinements in shader processing and memory management. The 240 shading units and 80 TMUs in this card represent a substantial increase over typical GeForce 9 parts, which generally had fewer unified shaders. The 448-bit memory bus is also a defining feature that separates it from the narrower buses common in the predecessor line.

GeForce 400 (Successor): The GeForce 400 series followed this card. The successor introduced a new architecture (Fermi) that brought support for newer DirectX features and a different shader model. While the GTX 275 PhysX Edition supports DirectX 11.1 (10_0 feature level), the actual feature set is limited to DirectX 10-level hardware. The GeForce 400 series moved to DirectX 11 as a native feature. The 50th percentile ranking versus all GPUs indicates that this card sits exactly in the middle of the performance distribution, which suggests it was a mid-range performer even in its own time.

FAQ

Q: Does this card support DirectX 11?

A: The card reports support for DirectX 11.1, but only at the 10_0 feature level. This means it can run DirectX 11 applications in API compatibility mode, but it does not have the full hardware features of a true DirectX 11 GPU. For practical purposes, treat it as a DirectX 10 card.

Q: What is the maximum resolution I can use with this card?

A: The card has 896 MB of GDDR3 memory on a 448-bit bus with 127.0 GB/s bandwidth. This is sufficient for 1080p gaming in older titles. For resolutions above 1080p, the memory capacity and 17.72 GPixel/s pixel rate are insufficient for modern games, leading to texture thrashing and low frame rates.

Q: Does the PhysX Edition require special drivers?

A: The FACT PACK does not specify driver requirements. The card is end-of-life, so driver support is limited to legacy versions. The PhysX branding indicates dedicated hardware for physics processing, but the data does not provide driver-level details.

Q: What power supply do I need?

A: The suggested PSU rating is 550 W. The card requires one 6-pin and one 8-pin PCIe power connector. Ensure your power supply has an available 8-pin cable, as some older units only provide 6-pin connectors.

Q: Can I use this card for modern gaming at 1080p?

A: The 50th percentile ranking suggests average performance. For modern AAA titles at 1080p, the 896 MB VRAM will be a severe bottleneck. The card is better suited for games from 2010-2013 or esports titles with low graphics requirements.

Q: How many monitors can I connect?

A: The card provides 2x DVI display outputs. It supports dual-monitor setups, but the 896 MB memory is shared across displays, so running two high-resolution monitors will reduce available VRAM for gaming.

Benchmark Performance

The GTX 275 PhysX Edition has an average benchmark score of 0, which is a placeholder value in the database, not a meaningful performance metric. The more informative figure is the percentileVsAllGpus of 50. This places the card at the exact median of the GPU performance distribution. In practical terms, half of all GPUs in the database perform better, and half perform worse. This is a rare and precise positioning.

Given the absence of nearestRivals data, a direct percentage comparison is impossible. The data shows no rival scores or deltaPct values to analyze. The card's raw compute figures provide context: 622.1 GFLOPS of FP32 performance, 50.64 GTexel/s texture fill rate, and 17.72 GPixel/s pixel rate. These numbers indicate a mid-range part from the GeForce 200 generation.

The 240 shading units at a memory clock of 1134 MHz (2.3 Gbps effective) suggest balanced throughput for the era. The texture rate of 50.64 GTexel/s is substantial for handling detailed textures at 1080p, but the pixel rate of 17.72 GPixel/s limits fill-rate-heavy scenarios like anti-aliasing and high resolutions. The card's 28 ROPs are the final stage for pixel output, and this is where the card shows its age. Modern GPUs have more ROPs, which is why this card falls behind.

In games from its release period (2010), the card would perform admirably at 1080p with high settings. The 50th percentile ranking suggests it was a mainstream performer, not a flagship. For comparison, a card at the 75th percentile would be significantly faster, while a card at the 25th percentile would be noticeably slower. The lack of specific rival data means we cannot quantify these gaps, but the percentile provides a solid qualitative anchor.

Memory Subsystem

The GTX 275 PhysX Edition is equipped with 896 MB of GDDR3 memory, which is an unusual capacity. This is not a standard 1 GB or 512 MB configuration. The 448-bit memory bus is wide, which is a hallmark of higher-end GPUs from that generation. The memory operates at 1134 MHz, translating to 2.3 Gbps effective. This yields a total memory bandwidth of 127.0 GB/s.

The 448-bit bus is the key differentiator here. A wider bus allows more data to be transferred per clock cycle, which mitigates the lower clockspeed of GDDR3 compared to newer memory types. The 127.0 GB/s bandwidth is respectable for 2010-era standards, but it is far below what modern GDDR6 or GDDR6X cards offer. For 1080p gaming, this bandwidth is adequate for moderate texture loads. The 896 MB capacity, however, is the limiting factor.

At 1080p with high-resolution textures, modern games can exceed 896 MB of VRAM usage easily. When the memory is exhausted, the card must fall back to system RAM over the PCIe 2.0 x16 bus, which causes stuttering and severe frame drops. For 1440p or higher, the 127.0 GB/s bandwidth becomes a bottleneck even before the capacity issue arises, as the pixel fill rate requirement exceeds what the memory can supply.

The 28 ROPs are responsible for final pixel output, and they operate at a pixel rate of 17.72 GPixel/s. This is a fixed function block that must write to the framebuffer. With 127.0 GB/s of bandwidth, the ROPs have enough throughput for 1080p at moderate frame rates. The memory subsystem as a whole is balanced for 1080p/30-60 FPS in older titles, but it is not future-proof. The 448-bit bus is a point of interest for hardware enthusiasts, as it was a feature of high-end NVIDIA parts, but the small VRAM capacity undermines its advantage in modern workloads.
