AMD Radeon HD 6750M Mac Edition

The AMD Radeon HD 6750M Mac Edition is an AMD mobile GPU built around the Whistler chip using the TeraScale 2 architecture. It was released on 2011-04-17, fabricated by TSMC on a 40 nm process, and packs 716 million transistors into a 118 mm² die, giving a transistor density of 6.1 million per square millimeter. The part belongs to the Vancouver generation (HD 6700M), uses an MXM-A (3.0) interface in an MXM Module form factor, carries a 35 W TDP, and is listed as end-of-life.

Benchmark Performance

The benchmark data for this GPU is sparse. There are no individual benchmark results in the listing, the average benchmark score is 0, and the nearest-rivals list is empty. The only comparative marker is the 50th-percentile position among all GPUs in the database. That places this part in the middle of the distribution, but with no sample scores and no rival deltas, the percentile cannot be turned into concrete percentage leads or deficits against specific products.

What can be analyzed is the fixed throughput ceiling. The GPU has 480 shading units, 24 texture mapping units, and 8 raster output units. That configuration yields a peak FP32 rate of 574.1 GFLOPS, a texture fill rate of 14.35 GTexel/s, and a pixel fill rate of 4.784 GPixel/s. These are the hardware limits for compute, texture work, and pixel output. The 40 nm TSMC process with 716 million transistors and a 118 mm² die supplies the logic, while the memory clock is set to 794 MHz, or 3.2 Gbps effective.

Because no nearest rivals are given, there are no deltaPct values to quote. No statement such as “X percent ahead of Y in multi-core” can be made from this listing. The 50th-percentile figure is the only placement anchor, and it indicates median standing within the database rather than a measured run. Performance conclusions therefore have to come from the architectural specifications rather than from game or synthetic benchmark data.

Who Should Consider It

This is a low-power mobile module rather than a desktop card. At 35 W TDP and with an MXM-A (3.0) interface, it is aimed at portable systems that accept replaceable MXM modules. The display outputs are portable-device dependent, so real-world use is tied to the laptop’s panel and output wiring rather than to a fixed set of desktop connectors.

The memory subsystem is the biggest practical constraint. With 512 MB of GDDR5, the frame buffer is small. Combined with a 128-bit bus and 50.82 GB/s of bandwidth, this GPU is better matched to lower-resolution frame buffers than to high-resolution ones. The pixel fill rate of 4.784 GPixel/s points the same way: lower pixel counts keep the ROPs from becoming the limiting factor. The texture rate of 14.35 GTexel/s is the matching cap for filtered texture work.

Without recorded benchmark scores, this analysis cannot name specific games or settings. The combination of 574.1 GFLOPS FP32 throughput, 512 MB VRAM, and 24 TMUs suggests modest detail levels and lower resolutions for 3D workloads. It is only a candidate for systems that use the same MXM-A (3.0) connection and stay within the same 35 W power envelope. End-of-life status means that availability is from legacy stock or used units.

Ray Tracing and Feature Set

The feature set is defined by TeraScale 2. The API table lists DirectX 11.2 with feature level 11_0, plus OpenGL 4.4. No Vulkan support is listed. The specification data also lists no RT cores and no tensor cores, so dedicated ray tracing hardware is not part of this GPU’s feature set.

Without tensor cores, tensor-based acceleration is absent from the listed specification. The absence of Vulkan in the API list means the supported low-level paths are DirectX 11_0 and OpenGL 4.4. The 480 shading units and 24 TMUs carry the geometry and texture work, while the 8 ROPs finish the raster pipeline. The 40 nm process and 716 million transistor budget define the area and power envelope for those units.

How It Compares

No nearest rivals are listed for this part. The nearest-rivals data is empty, so there are no rival GPU names, no scores, and no deltaPct values to reference. Without those entries, no direct comparison against other specific GPUs can be stated.

The product lineage does place it between two named parts: the predecessor is Manhattan and the successor is London. Those are generation markers, not benchmark rivals. The only quantitative placement available is the 50th-percentile figure. That puts the HD 6750M Mac Edition at the median of the database’s GPU population, but it does not say which GPUs are nearby or by how far. In the absence of comparator data, the accurate comparison is: no direct comparison is available.

Memory Subsystem

The memory subsystem consists of 512 MB of GDDR5 on a 128-bit bus. The memory clock is 794 MHz, translating to 3.2 Gbps effective, and the resulting bandwidth is 50.82 GB/s. These figures govern how quickly data can move between the GPU and its frame buffer.

For high-resolution output, capacity is the first limitation. 512 MB must hold color buffers, depth buffers, textures, and other render targets. The 128-bit bus then restricts peak transfer rate, with 50.82 GB/s as the aggregate ceiling. GDDR5’s 3.2 Gbps effective data rate helps make use of that narrow bus, but it does not add capacity. On the compute side, the 574.1 GFLOPS FP32 figure is paired with that bandwidth; memory-bound work is ultimately capped by the 50.82 GB/s transfer rate.

The 8 ROPs can write up to 4.784 GPixel/s, which is directly tied to pixel output. At high resolutions, more pixels are written per frame, so both the ROP rate and the 512 MB frame buffer become pressure points. The 24 TMUs with 14.35 GTexel/s set texture throughput limits independent of bus width.
