ATI Radeon HD 4700

The ATI Radeon HD 4700 is a late-generation entry within the Radeon R700 family, built on TSMC’s 55 nm process with the RV730 chip. It employs the TeraScale architecture, packing 514 million transistors into a 146 mm² die, and was released in February 2010 as an end-of-life product. With a 50th percentile ranking among all GPUs and no direct benchmark scores or nearest rivals recorded, its position is defined entirely by its architectural specifications and feature set.

Benchmark Performance

The FACT PACK lists no synthetic benchmark scores or comparative percentages for the ATI Radeon HD 4700. Its `avgBenchmarkScore` is zero, and the `nearestRivals` array is empty, meaning there is no quantitative data to analyze against competing products. The only performance indicators are derived from its fixed-function hardware rates: a pixel rate of 4.800 GPixel/s, a texture rate of 19.20 GTexel/s, and a peak FP32 compute of 384.0 GFLOPS.

These figures are moderate for the era. The 384.0 GFLOPS FP32 throughput comes from 320 shading units operating at the reference memory clock domain, which is typical for a mainstream part. The 12.80 GB/s memory bandwidth, drawn from a 128-bit bus with DDR2 memory at 400 MHz (800 Mbps effective), is a clear constraint. In any memory-heavy workload, this bandwidth ceiling would bottleneck the shading units, making the HD 4700 more competitive in fill-rate-bound scenarios than in bandwidth-heavy compute tasks.

The 50th percentile ranking implies the card sits exactly at the median of all GPUs in the database, but without explicit rival scores or deltas, the percentile is a standalone fact rather than a comparative measure. The data suggests a card that is neither a low-end outlier nor a performance leader; it is a middle-of-the-road product whose real-world results would be heavily influenced by driver maturity and system memory configuration. Because no benchmark numbers exist, any assertion about its relative speed against specific rivals would be speculation, and this analysis must restrict itself to the stated rates.

How It Compares

The FACT PACK provides no `nearestRivals` entries, so there are no rival names, scores, or deltaPct values to reference. Consequently, no direct comparison paragraphs can be constructed. The card’s predecessor is listed as Radeon R600, and its successor is Evergreen, but no performance deltas between these generations are supplied.

In the absence of rival data, the HD 4700’s position must be inferred from its hardware class. Its 8 ROPs and 32 TMUs, combined with a 128-bit memory bus, place it in the entry-to-midrange segment of the R700 lineup. The 55 nm process and 146 mm² die size indicate a cost-optimized design, not a flagship. The lack of any recorded benchmark scores means the card’s actual competitiveness cannot be quantified; it exists in the database as a specification sheet rather than a measured performer.

Given the empty rival list, the only factual statement about its standing is the 50th percentile rank, which is a global aggregate position rather than a head-to-head result. This percentile suggests that, among all GPUs tracked, the HD 4700 is neither exceptional nor deficient—it occupies the statistical middle. Without rival deltas, no further positioning is possible.

Ray Tracing and Feature Set

The ATI Radeon HD 4700 has no dedicated ray tracing cores (`rtCores: null`) and no tensor cores (`tensorCores: null`). This is consistent with its TeraScale architecture, which predates hardware-accelerated ray tracing and AI-based tensor operations. Any ray tracing workloads would have to run on the general-purpose shading units, which is not a supported or practical scenario for this generation.

API support is limited to DirectX 10.1 (shader model 10_1) and OpenGL 3.3. There is no Vulkan support, as the card predates the Vulkan specification. The absence of these modern APIs means the HD 4700 cannot leverage contemporary graphics features such as async compute or explicit multi-GPU via Vulkan. DirectX 10.1 is a minor revision over 10.0, adding features like improved shader model 4.1 and better multisample anti-aliasing, but it falls short of DirectX 11’s tessellation and compute shaders.

The display outputs are 2x DVI and 1x S-Video, which limits connectivity to older monitors and TVs. There is no HDMI or DisplayPort, so audio over HDMI or high-resolution single-cable connections are unavailable. The bus interface is PCIe 2.0 x16, which provides adequate bandwidth for the 12.80 GB/s memory throughput but is not a limiting factor given the card’s modest data rates. The feature set is firmly rooted in the late-2000s era: no hardware ray tracing, no tensor acceleration, and no modern API support.

FAQ

Q: What is the memory configuration of the ATI Radeon HD 4700?

A: It has 512 MB of DDR2 memory on a 128-bit bus, with a memory clock of 400 MHz (800 Mbps effective), yielding a bandwidth of 12.80 GB/s.

Q: Does the HD 4700 support DirectX 12 or Vulkan?

A: No. The card supports DirectX 10.1 (10_1) and OpenGL 3.3 only. Vulkan support is null, and DirectX 12 is not listed.

A: The card delivers 384.0 GFLOPS of FP32 compute, derived from its 320 shading units.

Q: How many ROPs and TMUs does it have?

A: It has 8 ROPs and 32 TMUs, producing a pixel rate of 4.800 GPixel/s and a texture rate of 19.20 GTexel/s.

Q: What is the production status and release date?

A: The production status is end-of-life, and it was released on February 10, 2010.

Q: What is the die size and transistor count?

A: The RV730 chip has 514 million transistors on a 146 mm² die, fabricated on a 55 nm process by TSMC, with a transistor density of 3.5 million per mm².

Power and Cooling

The ATI Radeon HD 4700 has a thermal design power (TDP) of 50 W, which is modest by any standard. This low power draw means it does not require a supplementary power connector; the FACT PACK lists `powerConnectors: null`. The suggested power supply is 250 W, which is a conservative recommendation for a system with this GPU, leaving headroom for the rest of the platform.

The card is a single-slot design with a physical length of 193 mm (7.6 inches). This compact footprint and low TDP make it suitable for small form-factor cases or legacy systems with limited space and power delivery. The 50 W TDP also implies that a capable air cooler—such as the one included on the card—would be sufficient; no liquid cooling or oversized heatsink is necessary.

The absence of a power connector is notable; it means the card draws all its power from the PCIe 2.0 x16 slot, which supplies up to 75 W by specification. With a 50 W TDP, the card operates well within slot power limits, reducing installation complexity. The 250 W PSU recommendation is a system-level guideline, not a GPU-specific requirement, and it accounts for the rest of the components (CPU, drives, motherboard) rather than the GPU alone.

Given the 50 W TDP, the HD 4700 is a low-power part that generates minimal heat. The single-slot cooler is adequate, and the card’s short length (193 mm) ensures compatibility with most chassis. The lack of external power connectors simplifies cabling, and the 250 W PSU suggestion is easily met by most modern power supplies, even those from the card’s release era.
