About ATI Mobility Radeon HD 5770
ATI Mobility Radeon HD 5770 is a mobile graphics processor from AMD, built on the TeraScale 2 architecture and fabricated on a 40 nm process at TSMC. The chip, codenamed Madison, packs 627 million transistors into a 104 mm² die, yielding a transistor density of 6.0M per mm². This GPU is positioned within the Manhattan generation of Mobility HD 5700 parts, and it has reached end-of-life status, having been released on the 2010-01-06. The benchmark percentile places it at the 50th percentile against all GPUs, indicating a mid-pack standing in the overall performance distribution.
Benchmark Performance
The ATI Mobility Radeon HD 5770 delivers a raw compute throughput of 520.0 GFLOPS in FP32 operations, a figure that reflects its 400 shading units operating in a TeraScale 2 arrangement. The pixel fill rate is 5.200 GPixel/s, while the texture fill rate reaches 13.00 GTexel/s, derived from 20 texture mapping units and 8 ROPs. These numbers position the GPU as a capable performer for its era, though the absence of nearest rival data means direct percentage comparisons cannot be established. The 50th percentile ranking suggests that in a broad field of GPUs, this part sits exactly at the median — neither a standout nor a laggard, but representative of typical mobile graphics capability at the time of its release.
Benchmark results indicate that the FP32 throughput of 520.0 GFLOPS is the primary driver of overall performance, as TeraScale 2 architectures rely heavily on shader core count for computational tasks. The texture rate of 13.00 GTexel/s and pixel rate of 5.200 GPixel/s are balanced for a 128-bit memory interface, ensuring that texture-heavy workloads do not starve the render output stage. In practical terms, the data shows a GPU that can handle mainstream gaming at moderate settings, but the 50th percentile standing implies it will struggle against higher-end parts from the same generation. The lack of rival comparisons in the data pack means no exact deltas can be cited; however, the percentile alone suggests a mid-tier position where performance gains over integrated graphics are substantial, but discrete high-end mobile GPUs would offer significantly more headroom.
Ray Tracing and Feature Set
This GPU does not include dedicated ray tracing cores or tensor cores, as neither field is populated in the specification data. The feature set is instead defined by its API support: DirectX 11.2 (11_0) and OpenGL 4.4, with no Vulkan support listed. This places the ATI Mobility Radeon HD 5770 firmly in the pre-ray-tracing era, where rendering relied on traditional rasterization techniques rather than hardware-accelerated ray tracing. The absence of tensor cores also means no AI-accelerated features such as DLSS are available, which is consistent with a TeraScale 2 architecture that predates such technologies.
The DirectX 11.2 support is notable, as it enables tessellation and other DX11-era effects, but the lack of Vulkan compatibility limits modern API adoption. For users of this GPU, the feature set is sufficient for games designed around DirectX 11, but any title requiring newer APIs or ray tracing will be outright incompatible. The 40 nm process node and 30 W thermal design power (TDP) indicate that this is a power-efficient part, but the feature set is strictly legacy by modern standards. The display outputs are described as "Portable Device Dependent," meaning connectivity varies by laptop implementation, and the PCIe 2.0 x16 bus interface is standard for its generation.
Who Should Consider It
The ATI Mobility Radeon HD 5770 is suited for users running games at lower resolutions and modest settings, given its 520.0 GFLOPS FP32 performance and 5.200 GPixel/s pixel rate. At a 50th percentile standing, the GPU can handle 720p gaming with medium to low detail in titles from its era, but modern releases will likely require significant compromises. The 1024 MB VRAM is adequate for 720p, but at higher resolutions the 128-bit memory bus becomes a limiting factor, as texture data will exceed the available bandwidth. For 1080p gaming, the data suggests the GPU will struggle with high-quality settings, and users should expect to lower resolutions or graphical presets to achieve playable frame rates.
This GPU is not recommended for users seeking high-refresh-rate or ultra-high-definition experiences, as the pixel rate and texture rate are insufficient for such demands. Instead, it is a viable option for legacy gaming, media playback, or as a basic display adapter for productivity workloads where 3D performance is secondary. The 30 W TDP makes it suitable for thin-and-light laptops where battery life is prioritized over raw performance. The lack of ray tracing and tensor cores further restricts its use case to traditional rasterized content, ruling out any modern AAA titles that leverage those features. The 50th percentile ranking reinforces that this is a mainstream part, not a performance or enthusiast offering.

Memory Subsystem
The memory subsystem consists of 1024 MB of GDDR5 memory, connected via a 128-bit bus. The memory clock runs at 800 MHz, translating to 3.2 Gbps effective data rate, which yields a total bandwidth of 51.20 GB/s. This bandwidth is moderate by modern standards, but for a 2010-era mobile GPU, it is sufficient for the pixel and texture rates achieved. The 128-bit bus width is a key constraint — it limits the amount of data that can be transferred to and from the GPU, which becomes critical at higher resolutions where texture and framebuffer data grow substantially.
At 1024 MB, the VRAM capacity is adequate for 720p gaming, but at 1080p or higher, the 51.20 GB/s bandwidth can become a bottleneck. The pixel rate of 5.200 GPixel/s and texture rate of 13.00 GTexel/s are well-matched to this memory bandwidth, suggesting that the GPU is balanced rather than memory-starved at its intended performance level. However, any workload that exceeds the VRAM capacity will incur spillover to system memory, degrading performance further. The GDDR5 type is a step up from DDR3, offering higher bandwidth per pin, but the 128-bit bus caps the overall throughput at 51.20 GB/s. For users with high-resolution displays, this memory subsystem will limit the effective resolution and detail settings, making the GPU better suited to 1366x768 or 1600x900 panels with reduced quality settings.
