ATI Mobility Radeon HD 5850

AMD’s ATI Mobility Radeon HD 5850 is a mobile GPU built around the Broadway chip using the TeraScale 2 architecture. TSMC manufactured it on a 40 nm process, with 1,040 million transistors on a 166 mm² die, and the GPU is rated at 30 W TDP. It was released on January 6, 2010 as part of the Manhattan generation (Mobility HD 5800), with the M9x as predecessor and Vancouver as successor. The database’s benchmark array is empty, the average benchmark score is 0, and the nearestRivals list contains no entries, so the analysis below is based on the listed specifications and the GPU’s 50th-percentile rank among all GPUs.

Benchmark Performance

Because there are no recorded benchmarks for this GPU, there are no measured frame rates or synthetic scores to place against other parts. The nearestRivals list is empty, which means exact percentage deltas cannot be calculated from the data on file. The only relative signal is percentileVsAllGpus: a value of 50 places the Mobility Radeon HD 5850 at the midpoint of the database’s GPU population. That is a broad positional statement, not a substitute for benchmark data.

The theoretical throughput figures define the performance envelope. The GPU has 800 shading units, 40 TMUs, and 16 ROPs. Single-precision compute peaks at 800.0 GFLOPS, texture filtering at 20.00 GTexel/s, and pixel throughput at 8.000 GPixel/s. These are the raw ceilings for shader work, texture work, and raster output. The pixel rate is notably low compared with the texture rate, which suggests the design leans toward shading and texture-bound workloads rather than high-resolution pixel pushing.

Clocks are only partially specified in the database. Base and boost clocks are not listed, while memory is listed at 1000 MHz, or 4 Gbps effective. The memory clock feeds a 128-bit bus to produce 64.00 GB/s of bandwidth. Without base or boost clock entries, shader clock behavior cannot be reconstructed from the data. The 800.0 GFLOPS figure stands as the stated reference point for compute performance.

The API support is also part of the performance context. DirectX 11.2 (11_0) and OpenGL 4.4 are listed, while Vulkan is not. These API versions describe which software interfaces the GPU can target, but they do not supply benchmark scores. For a 30 W mobile GPU with an empty benchmark record, the performance story rests on these theoretical rates and the mid-pack percentile.

Who Should Consider It

With no game scores on file, resolution and settings guidance has to be inferred from the memory and fillrate data. The GPU has 1024 MB of GDDR5, a 128-bit memory bus, 64.00 GB/s bandwidth, and 8.000 GPixel/s pixel rate. That combination points toward workloads where frame buffer capacity and memory bandwidth are not stretched by large high-resolution render targets. In practice, that means lower resolutions and modest detail settings; the database does not contain frame-rate evidence to be more specific.

Users who specifically need a GPU with DirectX 11.2 (11_0) and OpenGL 4.4 support for older or lightweight software can find those APIs here. Vulkan is not listed, so Vulkan-only applications are outside the feature set. Display outputs are portable-device dependent, meaning compatibility with a particular laptop’s display or output ports is determined by the original equipment design, not by the GPU data.

The 30 W TDP is the only power figure in the data. Slot width, power connectors, and suggested PSU are all absent from the record, so system integration is tied to the original laptop design. Since the production status is end-of-life and no measured performance scores exist, this is a part for legacy hardware rather than for current high-load gaming. Any recommendation based on settings must remain conditional because there is no benchmark evidence to confirm how the specification limits translate into actual performance.

Ray Tracing and Feature Set

Ray tracing hardware is absent from this GPU. The rtCores field is null, and tensorCores are also null. The feature set is therefore built entirely around the TeraScale 2 shader array of 800 shading units, with 40 TMUs and 16 ROPs. This is a pre-dedicated-RT architecture, and the null core fields confirm that no hardware ray tracing or tensor acceleration blocks are present.

Supported graphics APIs are DirectX 11.2 (11_0) and OpenGL 4.4. Vulkan is not listed. The host interface is PCIe 2.0 x16. Display outputs are portable-device dependent, so the physical output options are tied to the laptop implementation rather than to the GPU package.

Without RT or tensor cores, any ray-traced or tensor-accelerated workload would have to be handled through general-purpose shader execution on the 800 shading units. The 20.00 GTexel/s texture rate and 8.000 GPixel/s pixel rate define the traditional rendering limits. The API list shows a DirectX 11.2 feature level of 11_0, which is the relevant API-generation marker for this chip.

FAQ

Q: How much memory does the ATI Mobility Radeon HD 5850 have?

A: It has 1024 MB of GDDR5 memory on a 128-bit bus, with 64.00 GB/s bandwidth. The memory clock is 1000 MHz, or 4 Gbps effective.

Q: Does this GPU support Vulkan?

A: No. The database lists DirectX 11.2 (11_0) and OpenGL 4.4 as supported APIs; Vulkan is not listed.

Q: Is there hardware ray tracing?

A: No. The rtCores and tensorCores fields are null, so there is no dedicated ray tracing or tensor hardware in the data.

Q: What is the manufacturing process?

A: The Broadway chip is made by TSMC on a 40 nm process, with 1,040 million transistors on a 166 mm² die, for a transistor density of 6.3M / mm².

Q: What is the power draw?

A: The TDP is 30 W. Power connectors, slot width, and suggested PSU are not listed.

Q: What generation does it belong to?

A: It belongs to the Manhattan generation (Mobility HD 5800), with the M9x as its predecessor and Vancouver as its successor. Its production status is end-of-life.

Memory Subsystem

The memory subsystem is fully specified: 1024 MB GDDR5, 128-bit bus, 64.00 GB/s bandwidth, and a memory clock of 1000 MHz with 4 Gbps effective. The 128-bit bus is the path over which all frame buffer data moves. At high resolutions, the combination of a 128-bit bus and 64.00 GB/s bandwidth limits how quickly textures and render targets can be accessed.

The GPU’s 16 ROPs deliver a pixel rate of 8.000 GPixel/s, while the 40 TMUs deliver 20.00 GTexel/s. These rates, alongside the 64.00 GB/s bandwidth, are the practical ceilings for memory-bound rendering. The 1024 MB frame buffer is the listed capacity, and the database does not record a larger variant. For a 30 W mobile design, this memory configuration represents a modest bandwidth-to-compute balance, but with no benchmark scores, the real-world impact cannot be quantified.

The host connection is PCIe 2.0 x16. Display outputs are portable-device dependent, so the memory subsystem is the fixed part of the display path while external connectivity depends on the laptop. The data lists one memory configuration, with no expansion details. All of this points to a GPU that is capacity- and bandwidth-limited relative to its 800.0 GFLOPS compute rate, especially when frame sizes grow beyond what the 128-bit bus and 64.00 GB/s pipe can comfortably feed.
