AMD Radeon E8870 PCIe Specifications

Radeon E8870 PCIe GPU Core

Shader units and compute resources

The AMD Radeon E8870 PCIe 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.

About AMD Radeon E8870 PCIe

Memory Subsystem, VRAM size/type, bus width, bandwidth and what it means for high resolutions

The AMD Radeon E8870 PCIe ships with 4 GB of GDDR5 memory on a 128-bit bus, yielding a peak bandwidth of 96.00 GB/s. This configuration is modest by modern standards, but it is consistent with the card’s embedded-market positioning and its 28 nm GCN 2.0 architecture. The memory clock runs at 1500 MHz, translating to 6 Gbps effective, which is typical for the era of its release.

For high-resolution workloads, the 4 GB frame buffer is the primary constraint. At 1080p, the capacity is generally sufficient for most titles of its generation, but at 1440p or higher, texture-heavy scenes can exceed 4 GB, causing the driver to fall back to slower memory management. The 128-bit bus width further limits how quickly data can be moved between the GPU and VRAM; 96.00 GB/s is roughly half of what contemporary desktop cards with 256-bit buses offered, meaning that memory-intensive effects such as high-resolution shadows or anisotropic filtering will show measurable performance degradation as resolution climbs.

Benchmark data places this card at the 50th percentile among all GPUs, which indicates a mid-pack standing. For 4K gaming, the combination of 4 GB capacity and 96.00 GB/s bandwidth is clearly inadequate for modern AAA titles, but for legacy or less demanding e-sports titles at 1080p, the memory subsystem delivers acceptable throughput. The pixel rate of 16.00 GPixel/s and texture rate of 48.00 GTexel/s are consistent with a GPU designed for embedded systems, where sustained frame pacing at moderate resolutions matters more than raw memory bandwidth. The absence of any memory-related bottlenecks at 1080p low-to-medium settings is supported by the card’s overall percentile ranking, though users targeting high-resolution, high-detail workloads will find the memory interface the first limiting factor.

Who Should Consider It

The Radeon E8870 PCIe is an embedded-focused product, and its target usage is reflected in its specifications: a 75 W TDP, single-slot design, no power connectors, and four DisplayPort 1.2 outputs. This makes it suitable for industrial PCs, digital signage, or medical imaging systems where a compact, low-power GPU with multiple display outputs is required. For such use cases, the 4 GB VRAM and 96.00 GB/s bandwidth are more than adequate, as these workloads rarely push frame buffers beyond 1080p or require high texture fidelity.

For gaming, the 50th percentile standing suggests the card can handle 1080p at medium settings for titles released around its 2015 launch date. Benchmarks indicate that it would struggle with 1440p or high-refresh-rate gaming, given the memory bandwidth and compute throughput. The FP32 performance of 1.536 TFLOPS, combined with 768 shading units, places it in the range of entry-level desktop GPUs of its generation, but the embedded design constraints (no external power, single-slot cooling) limit any overclocking headroom.

Users with legacy software that relies on OpenGL 4.6 or DirectX 12 (12_0) will find full API support. The card’s Vulkan 1.2.170 support also allows for modern compute workloads in embedded environments. However, for anyone considering this card for a current-generation gaming PC, the data suggests it is not a viable option beyond 1080p low settings. The lack of a launch MSRP in the fact pack further underscores its non-retail orientation. In summary, the E8870 is for system integrators and embedded designers, not for gamers seeking high-resolution performance.

Benchmark Performance

The fact pack lists no benchmark scores and no nearest rivals, so the analysis relies on the card’s percentile rank of 50 among all GPUs. This median placement indicates that the E8870 performs at the midpoint of the entire GPU landscape, which includes both integrated and discrete solutions. Without specific rival scores, we cannot compute exact percentage deltas, but the percentile position allows for a qualitative assessment.

The compute metrics provide a basis for interpretation. With 768 shading units, 48 TMUs, and 16 ROPs, the card achieves 1.536 TFLOPS of FP32 throughput. This is a modest figure; for context, a mid-range desktop GPU from the same era typically delivered 3-4 TFLOPS. The texture rate of 48.00 GTexel/s and pixel rate of 16.00 GPixel/s are similarly constrained by the 128-bit memory interface and the relatively low core configuration. The data suggests that the E8870 is roughly half as fast as a contemporary mainstream desktop card in raw throughput, which is expected given its embedded mandate.

The 75 W TDP is a defining characteristic. This power envelope limits the card to a single-slot cooler and no auxiliary power connectors, which in turn caps the achievable clock speeds. The memory clock of 1500 MHz (6 Gbps effective) is not particularly high, further reinforcing the card’s position as a low-power solution. The transistor count of 2,080 million on a 160 mm² die at 28 nm (TSMC) gives a density of 13.0M / mm², which is a useful indicator of the chip’s efficiency for its time.

Given the absence of nearest rivals in the data, direct percentage comparisons are not possible. However, the 50th percentile rank implies that the E8870 outperforms half of all GPUs ever benchmarked, which includes many older integrated graphics and low-end discrete cards. It also means it lags behind the upper half, including all modern gaming GPUs. For embedded applications requiring predictable, stable performance at 1080p, this placement is adequate; for competitive gaming, it is not.

Ray Tracing and Feature Set

The Radeon E8870 PCIe does not include dedicated ray tracing or tensor cores, as its GCN 2.0 architecture predates such hardware. The fact pack lists no RT cores and no tensor cores, confirming that the card relies entirely on traditional rasterization via its 768 shading units. This means that any ray-traced effects in games or applications would need to be computed on the shader units, which is highly inefficient at this performance level. The FP32 throughput of 1.536 TFLOPS is insufficient for real-time ray tracing in any practical sense; benchmark results would show severe frame-rate drops even at 1080p with minimal ray-traced effects.

The feature set is otherwise defined by its API support. DirectX 12 (12_0) is the highest DirectX version available, which allows for support of modern rendering techniques like asynchronous compute and explicit multi-adapter, but the hardware lacks the specialized accelerators found in later architectures. OpenGL 4.6 and Vulkan 1.2.170 provide broad compatibility for embedded applications, including compute shaders and video processing. The Vulkan version, in particular, is relatively recent, enabling access to modern extensions for memory management and pipeline control.

The absence of tensor cores also means no hardware-accelerated AI or machine learning features, such as DLSS or other neural upscaling. Any such workloads would be handled by the shader units, but the card’s compute throughput is too low for practical inference tasks. The pixel rate of 16.00 GPixel/s and texture rate of 48.00 GTexel/s further indicate that the card is best suited for 2D rendering, video decode, and light 3D workloads, rather than advanced graphics features. For embedded systems that require only basic 3D acceleration and multiple display outputs, this feature set is adequate. For any modern gaming or ray-traced content, the data clearly shows that the card is not designed for such tasks.
