AMD Radeon HD 7970 X2 Specifications

Radeon HD 7970 X2 GPU Core

Shader units and compute resources

The AMD Radeon HD 7970 X2 GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.

AMD's Radeon HD 7970 X2 Memory

VRAM capacity and bandwidth

VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The Radeon HD 7970 X2's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.

About AMD Radeon HD 7970 X2

The AMD Radeon HD 7970 X2 is an end-of-life graphics card from the Southern Islands (HD 7900) generation. It uses AMD's GCN 1.0 architecture with the New Zealand chip, built on TSMC's 28 nm process with 4,313 million transistors on a 352 mm² die, a transistor density of 12.3M/mm². The card connects via PCIe 3.0 x16 and was released on 2012-08-30 with a launch MSRP of 899 USD. In the database it holds a 50th-percentile rank among all GPUs and an average benchmark score of 0; the nearestRivals list is empty, so no comparative benchmark deltas are available.

Who Should Consider It

Because the average benchmark score is 0, there is no measured score from which to derive a conventional resolution or settings recommendation. The specification data provides the available guidance instead. The card has 3 GB of GDDR5 memory on a 384-bit bus, with 264.0 GB/s of bandwidth. That memory configuration is a high-bandwidth design aimed at large frame buffers. The GPU has 2048 shading units, 128 texture mapping units, and 32 ROPs, producing 3.789 TFLOPS of FP32 compute, 118.4 GTexel/s texture fill, and 29.60 GPixel/s pixel fill. These are strong theoretical figures for a card sitting at the 50th percentile of the database distribution. The 50th-percentile rank, however, indicates a median position rather than a top-tier standing.

Users considering this card should account for its large physical footprint. It is a triple-slot card measuring 308 mm by 137 mm by 62 mm, or 12.1 x 5.4 x 2.4 inches. It also requires three 8-pin power connectors and a suggested PSU of 900 W. The display outputs, consisting of 2x DVI, 1x HDMI 1.4a, and 2x mini-DisplayPort 1.2, allow multiple monitors to be connected. End-of-life status means it is not an actively produced product, so any purchase is from remaining inventory or the used market.

Ray Tracing and Feature Set

The FACT PACK lists no RT cores and no tensor cores for the HD 7970 X2. That means the record contains no hardware ray tracing units and no dedicated tensor core units. Feature support comes through API compatibility: DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The DirectX 12 label is qualified with the 11_1 feature level, which is the relevant detail of its API support. The architecture is GCN 1.0, and the chip is called New Zealand. No fp16 throughput value is present in the record. Display connectivity is provided by 2x DVI, 1x HDMI 1.4a, and 2x mini-DisplayPort 1.2.

Benchmark Performance

The benchmarks array in the FACT PACK is empty, and the nearestRivals array is also empty. As a result, no exact percentage deltas and no rival scores can be cited. The average benchmark score is 0. The percentileVsAllGpus value is 50, placing the card at the median of all GPUs in the database. Because the average score is 0, empirical performance cannot be measured from that metric.

The quantitative measures available are theoretical throughput values: FP32 at 3.789 TFLOPS, texture rate at 118.4 GTexel/s, and pixel rate at 29.60 GPixel/s. Memory runs at 1375 MHz for an effective 5.5 Gbps, yielding the 264.0 GB/s bandwidth already noted. No base, boost, or game clock values are listed, so clock-based analysis is limited to the memory clock. In short, the database position is median, but there is no measured performance result to support a percentage comparison with another product.

Power and Cooling

The TDP is 500 W, a high figure that explains the suggested PSU rating of 900 W. Power is delivered through 3x 8-pin connectors, so the power supply must provide three such connectors. The card occupies a triple-slot width and is 308 mm long, 137 mm tall, and 62 mm wide, or 12.1 x 5.4 x 2.4 inches. It was built on TSMC's 28 nm process with a 4,313-million-transistor die of 352 mm². The transistor density is 12.3M/mm². Despite the 28 nm process node, the TDP remains 500 W. The production status is end-of-life, and the release date is 2012-08-30.

Memory Subsystem

The memory subsystem consists of 3 GB of GDDR5 on a 384-bit bus. The memory clock is 1375 MHz, with an effective data rate of 5.5 Gbps, producing 264.0 GB/s of bandwidth. For a GPU with 2048 shading units, 128 TMUs, and 32 ROPs, this bandwidth is what feeds those units during rendering. The theoretical texture rate is 118.4 GTexel/s, and the pixel rate is 29.60 GPixel/s.

At high resolutions, the 3 GB capacity defines an absolute limit for frame buffer data, while the 264.0 GB/s bandwidth defines the rate at which data can move across the 384-bit bus. The memory clock of 1375 MHz sets the base operating frequency of the VRAM, and the 5.5 Gbps effective rate represents the data transfer speed after accounting for the GDDR5 signaling. The record does not list fp16 throughput, tensor cores, or RT cores, so the numeric profile for this card is centered on FP32 compute and the texture and pixel rates above.

How It Compares

The nearestRivals array is empty. There are therefore no rival names, scores, or deltaPct values to compare against. The only ranking data in the record is the 50th-percentile position among all GPUs and an average benchmark score of 0. That zero average score cannot serve as a measured comparison point. The card is located between two generations in the FACT PACK: Northern Islands is the predecessor, and Sea Islands is the successor. It belongs to the Southern Islands (HD 7900) generation. In the absence of rival entries, the comparative context is limited to the median database rank and the theoretical throughput values already listed.
