NVIDIA GeForce 7800 GT

The NVIDIA GeForce 7800 GT uses the G70 chip on NVIDIA's Curie architecture and belongs to the GeForce 7 PCIe (7800) generation. TSMC produced the 302-million-transistor, 333 mm² die on a 110 nm process, giving a listed transistor density of 906.9K per mm². The database names the GeForce 6 PCIe family as its predecessor and the GeForce 8 as its successor. Release is dated August 10, 2005, and the launch MSRP was 449 USD. The card is end-of-life, and the aggregate rank is the 50th percentile across all GPUs, with an empty benchmark array and an average benchmark score of 0.

Power and Cooling — TDP, PSU recommendation, connector requirements

The power section of the record is compact: a 65 W TDP, a single-slot form factor, one 6-pin power connector, and a suggested PSU of 250 W. The connector requirement is specifically 1x 6-pin, and the slot width is single-slot. The bus interface is PCIe 1.0 x16, which is the electrical connection used by this generation. A 65 W TDP paired with a 250 W suggested PSU defines the thermal and system-level power envelope: the card is rated to dissipate 65 W, while the supply recommendation is 250 W for the system. No other power draw figure is recorded, so the 65 W TDP is the only thermal reference point in the data.

The physical dimensions are 226 mm (8.9 inches) in length and 111 mm (4.4 inches) in height, with no width value supplied. The single-slot width captures the cooler envelope. These figures specify chassis clearance: one expansion slot, a 226 mm by 111 mm footprint, and a single 6-pin lead for power. The 250 W PSU figure is the database's recommendation for system integration, while the 65 W TDP is the card-level thermal limit. The 1x 6-pin connector is the only power connector listed, and the single-slot width indicates the cooler does not extend beyond one slot. Together, the checklist for installation is: 65 W thermal budget, 250 W PSU recommendation, one 6-pin connector, single-slot width, and the 226 mm by 111 mm board dimensions.

Ray Tracing and Feature Set

The database does not list RT cores or tensor cores for this card; both fields are null. Therefore, the record contains no hardware ray tracing acceleration data and no tensor processing data. The API section lists DirectX 9.0c (9_3), OpenGL 2.1, and no Vulkan version. Those are the only software feature ceilings in the entry. The rendering pipeline is further quantified by 20 TMUs, 16 ROPs, a pixel rate of 6.400 GPixel/s, and a texture rate of 8.000 GTexel/s. The pixel rate describes the output stage defined by the 16 ROPs, and the texture rate describes the work handled by the 20 TMUs.

Because RT core and tensor core fields are null, there is no ray tracing or tensor acceleration feature set to describe. The absence of a Vulkan value completes the API picture; no Vulkan compatibility is represented in the data. The DirectX version is recorded as 9.0c with the 9_3 version string, and OpenGL is recorded as 2.1. The Curie architecture label is the only microarchitectural name associated with the card. The combination of the API list and the 6.400 GPixel/s and 8.000 GTexel/s throughput figures constitutes the full feature set record in this database.

Memory Subsystem

The memory specification is a 256 MB frame buffer of GDDR3 attached via a 256-bit bus, running at 500 MHz with an effective 1000 Mbps data rate. The resulting bandwidth is recorded as 32.00 GB/s. These are the only memory-related figures in the database; there are no FP32 or FP16 throughput fields populated. For high-resolution use, the data provides two key numbers: capacity, 256 MB, and bandwidth, 32.00 GB/s. The 256-bit bus is the interface width over which that bandwidth is delivered, and the GDDR3 type is the memory technology used.

The record does not include benchmark results at any resolution, so how the 256 MB capacity and 32.00 GB/s bandwidth behave under load is not documented. The 50th percentile aggregate rank is the only performance-adjacent metric tied to the card, and it is not specific to memory behavior. The memory clock figures are 500 MHz and 1000 Mbps effective; the bandwidth figure is given as 32.00 GB/s. In short, the memory section states exactly what is physically fitted — 256 MB GDDR3, a 256-bit bus, and 32.00 GB/s of bandwidth — but does not quantify what those components achieve in actual workloads.

How It Compares

The nearestRivals field is empty. No rival names, scores, or deltaPct values are available for the GeForce 7800 GT in this database, so no computed comparison against competitor cards can be presented. The only comparative datum is percentileVsAllGpus = 50, which places the card at the midpoint of the GPU distribution. The average benchmark score of 0 and the empty benchmark array mean this percentile is not backed by any measured workload in the entry; it is a rank within the database, not a result from a specific test.

The generation field places the card in the GeForce 7 PCIe (7800) family, with GeForce 6 PCIe shown as predecessor and GeForce 8 as successor. Those lineage entries position the card between two neighboring NVIDIA families in the product sequence, but they do not provide performance deltas. Since the database lacks nearest rivals, any statement beginning with "the 7800 GT is ahead of" or "behind" cannot be written from the available data. The 50th percentile is the single quantifiable position: exactly halfway through the ranked list of all GPUs. No measured competitor deltas exist to refine that position.

Who Should Consider It

With no benchmark score array, the database cannot offer a measured frame-rate-based recommendation. The card's listed profile consists of a 50th percentile aggregate rank, a 65 W TDP, a 250 W suggested PSU, 256 MB GDDR3 on a 256-bit bus, 32.00 GB/s bandwidth, DirectX 9.0c (9_3) and OpenGL 2.1 support, and no RT or tensor core entries. Users who need those specific conditions are the audience indicated by the data.

Users planning high-resolution work should note that the only capacity figure is 256 MB; no high-resolution benchmark evidence is stored for this card. Users requiring Vulkan or hardware ray tracing will find no support in the record, since the Vulkan field is null and the RT/tensor core fields are null. The pixel rate of 6.400 GPixel/s and texture rate of 8.000 GTexel/s are the throughput figures available for assessing the output stage, but how they translate into game settings is not quantified by any benchmark score in this entry. The 50th percentile rank can be read as a middle-of-the-road placement, but with an average benchmark score of 0 and an empty benchmark array, that placement does not come with a specific performance envelope.

The practical checklist from the data is: 65 W power, a 250 W PSU recommendation, one 6-pin connector, a 226 mm by 111 mm footprint, single-slot width, 256 MB GDDR3, 32.00 GB/s bandwidth, DirectX 9.0c (9_3), and OpenGL 2.1. Those are the figures that define what this card is and what the database can say about it.
