AMD Radeon HD 8730 OEM

Memory Subsystem

The AMD Radeon HD 8730 OEM is equipped with 1024 MB of GDDR5 memory, which was the standard capacity for its class at the time of release. The memory operates across a 128-bit bus interface, a configuration that directly limits the theoretical peak bandwidth to 72.00 GB/s. This figure is derived from a memory clock of 1125 MHz, translating to an effective data rate of 4.5 Gbps per pin.

For high-resolution workloads, this memory subsystem presents a clear bottleneck. At 1080p, the 72.00 GB/s bandwidth is adequate for moderate texture loads and standard detail settings, but the card's 8 ROPs and 384 shading units will saturate the memory bus well before the GPU's compute potential is reached. The effective 4.5 Gbps data rate was competitive in the entry-level segment circa 2013, yet modern titles with large texture caches will exceed the 1 GB frame buffer quickly, causing texture swapping and stuttering. The 128-bit bus width, while modest, is appropriately matched to the card's pixel rate of 6.400 GPixel/s; increasing bandwidth without more ROPs would not yield proportional gains. In essence, the memory architecture is balanced for 720p and light 1080p gaming, but it lacks the headroom for 1440p or high-detail 4K textures, where the 72.00 GB/s figure becomes a hard ceiling.

Ray Tracing and Feature Set

The HD 8730 OEM does not include dedicated ray tracing or tensor cores, as its GCN 1.0 architecture predates those hardware blocks. Instead, the card relies on 384 shading units to handle all compute and graphics workloads, including any software-based ray tracing effects. The absence of RT cores means that real-time ray tracing is not a practical feature; any such workload would fall entirely on the shader array, resulting in performance far below playable thresholds.

The feature set is defined by its API support rather than dedicated accelerators. The card supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. This API trio is notable because it allows the GPU to run modern titles that mandate DX12 or Vulkan, even if the underlying hardware lacks the specialized units found in newer generations. The DirectX 12 (11_1) feature level is significant—it means the card can execute DX12 workloads at the 11_1 feature tier, which includes bindless resources and conservative rasterization, but not the higher-tier features like mesh shaders. Vulkan 1.2.170 support similarly opens the door to recent engines, though performance will be constrained by the 614.4 GFLOPS FP32 throughput. For display connectivity, the card offers 1x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2, enabling multi-monitor setups at standard refresh rates. The lack of tensor cores also means no AI-accelerated features like DLSS; any upscaling must be done through the shader units, which further taxes the 19.20 GTexel/s texture rate.

Benchmark Performance

The benchmark data for the HD 8730 OEM is sparse, with an average benchmark score of 0 and a percentile rank of 50 among all GPUs. This percentile placement is instructive: it places the card exactly at the median of the database, meaning half of all GPUs tested perform better and half perform worse. However, the average score of 0 is a null value, indicating that no standardized benchmarks were completed successfully or that the card was not subjected to the full testing suite. This makes direct numerical comparisons difficult, but the percentile rank of 50 provides a relative anchor.

Without nearest rival data, we must interpret the card's performance from its silicon characteristics. The 384 shading units at a 28 nm process node yield 614.4 GFLOPS of FP32 compute, which is roughly half the throughput of a mid-range card from the same generation. The texture rate of 19.20 GTexel/s and pixel rate of 6.400 GPixel/s are consistent with an entry-level part designed for 720p gaming at medium settings. In synthetic benchmarks, the card would likely score below the 50th percentile in compute-heavy tests like FurMark but could approach the 50th percentile in memory-bandwidth-bound tests, given the 72.00 GB/s figure is not egregiously low for a 128-bit bus. The 1,500 million transistors on a 123 mm² die, produced by TSMC, indicate a power-efficient design, which is reflected in the 47 W TDP.

The stark reality is that the HD 8730 OEM has no recorded benchmark scores to analyze. The percentile of 50 is a default placeholder, not a measured result. Therefore, any performance claims must be extrapolated from the clock and shader specifications, which point to a card that was entry-level in 2013 and is now severely outdated for modern gaming. The FP32 throughput of 614.4 GFLOPS is less than 10% of what a contemporary mid-range GPU offers, and the 8 ROPs will limit fill-rate-bound scenarios even at low resolutions.

How It Compares

The nearestRivals array is empty, meaning no direct comparative data is available in the fact pack. Consequently, we cannot provide specific percentage deltas against named competitors. The card's position must be inferred from its percentile rank of 50, which is a neutral placement in the database. This absence of rival data is itself informative: it suggests the card was not a popular benchmark subject, likely due to its OEM-only distribution and end-of-life status.

In the absence of direct rivals, we can contextualize the HD 8730 OEM against its own family. It is part of the Sea Islands generation (HD 8700), succeeding Southern Islands and preceding Volcanic Islands. This places it as a transitional product using the GCN 1.0 architecture, which was first introduced in the Southern Islands generation. The 28 nm process and 1,500 million transistors are identical to the Cape Verde chip used in other HD 8700 variants, but the OEM designation implies a stripped-down configuration with lower clocks or disabled units. The 384 shading units and 24 TMUs are the full Cape Verde complement, suggesting no disabled shader blocks, but the 8 ROPs are notably low for a 128-bit memory bus—many cards with a 128-bit bus feature 16 ROPs. This reduction likely explains the modest 6.400 GPixel/s pixel rate. Compared to its predecessor generation, the HD 8730 OEM offers GCN 1.0 features like improved compute and async compute, but the successor Volcanic Islands generation would bring higher clock speeds and better power efficiency. Without rival scores, the card's 50th percentile rank places it in a vast middle ground, but the lack of measured benchmarks means this rank is not validated by actual test data.

FAQ

Q: What is the memory bandwidth of the AMD Radeon HD 8730 OEM?

A: The memory bandwidth is 72.00 GB/s, calculated from a 128-bit bus width and 1125 MHz memory clock (4.5 Gbps effective on GDDR5).

Q: Does the HD 8730 OEM support hardware ray tracing?

A: No, the card does not have dedicated RT cores. It uses 384 shading units for all graphics workloads, and ray tracing would run in software with severely limited performance.

Q: What is the maximum API level supported by this GPU?

A: The card supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The DX12 support is at the 11_1 feature level, not the highest tier.
