About ATI Radeon HD 4670
The ATI Radeon HD 4670 is a graphics card manufactured by AMD, built around the RV730 chip and the TeraScale architecture. It belongs to the Radeon R700 (HD 4600) generation and was released on 2008-09-09. The chip is fabricated by TSMC on a 55 nm process, integrating 514 million transistors on a die measuring 146 mm², for a transistor density of 3.5M per mm². The card is now end-of-life, with its predecessor being the Radeon R600 line and its successor being the Evergreen architecture. Its launch MSRP was 67 USD.
Benchmark Performance
The database records an average benchmark score of 0 for the ATI Radeon HD 4670, indicating that no aggregated performance measurement has been captured for this part. The percentileVsAllGpus field places the card at 50, meaning it sits exactly at the median of the entire GPU population tracked by the database. Half of all GPUs in the database outperform it, and half underperform it. This is the most informative comparative metric available, because the nearestRivals list is empty and no direct rival scores or deltas are provided.
The compute core of the HD 4670 is defined by 320 shading units, 32 texture mapping units, and 8 raster operation units. These resources produce a peak FP32 throughput of 480.0 GFLOPS. The pixel fill rate is 6.000 GPixel/s, and the texture fill rate is 24.00 GTexel/s. These three figures describe the card's raw processing limits. The pixel rate of 6.000 GPixel/s bounds how many pixels can be written per second in fill-rate-bound scenarios. The texture rate of 24.00 GTexel/s bounds how many texels can be sampled per second. The FP32 figure of 480.0 GFLOPS bounds general-purpose and shader compute workloads.
Taken together, these numbers describe a card deliberately balanced for mainstream use. The 55 nm process, the 514 million transistor count, and the 146 mm² die size all point to a mid-range chip. A transistor density of 3.5M per mm² is consistent with the era's manufacturing technology. The 59 W TDP and the absence of any power connectors mean the card draws all its power from the PCIe 2.0 x16 slot, and the suggested power supply is a modest 250 W.
Because the average benchmark score is 0, the percentile ranking of 50 is the only performance signal in the data. A median position implies that the HD 4670 was neither a performance outlier nor a bottom-tier part within the database's population. For applications that are within its fill-rate and compute limits, the card can be expected to perform adequately, but the data does not include frame-rate measurements to quantify this.
The DirectX 10.1 (10_1) and OpenGL 3.3 API support define the software boundary. Titles that require newer APIs are not supported, which constrains the card's practical performance envelope to older software.
Memory Subsystem
The HD 4670 ships with 512 MB of GDDR3 memory. The memory bus is 128 bits wide, and the memory clock is 1000 MHz, which yields an effective data rate of 2 Gbps per pin. The aggregate memory bandwidth is 32.00 GB/s.
This bandwidth figure is the key constraint for high-resolution workloads. At higher resolutions, the number of pixels and texture samples per frame increases, which raises the demand for memory bandwidth. With 32.00 GB/s, the HD 4670 can sustain a certain amount of data movement per second; beyond that, performance is limited by the memory subsystem rather than the compute units. The 128-bit bus width is the physical limit on data transferred per clock cycle, and the 1000 MHz clock determines how many cycles occur per second. The product of these two factors is the 32.00 GB/s figure.
The 512 MB frame buffer is another limiting factor. Large textures, high-resolution render targets, or multi-buffered scenes may exceed the available memory, forcing the card to spill to system memory over the PCIe 2.0 x16 bus. The display outputs — 2x DVI and 1x S-Video — support common monitors of the era, but the memory capacity and bandwidth are the practical limits for what can be displayed smoothly.
In the context of the card's overall performance, the memory subsystem is well matched to the compute resources. The 32.00 GB/s bandwidth can feed the 320 shading units and 32 TMUs at rates consistent with the 480.0 GFLOPS FP32 throughput and the 24.00 GTexel/s texture rate. A faster memory subsystem would likely be underutilized by the compute core, while a slower one would create a bottleneck. The 512 MB capacity is modest, however, and applications with large memory footprints may be constrained by capacity rather than bandwidth.
Who Should Consider It
The ATI Radeon HD 4670 is a card for users whose requirements align with its median performance position. The 50th percentile ranking means it is neither a high-end nor a low-end part in the database's GPU population. Users who need a card for basic graphical output, legacy software, or systems with limited power delivery may find it suitable.
The power profile is a strong indicator of the intended use case. With a TDP of 59 W, no power connectors, and a suggested power supply of 250 W, the card can be installed in systems with modest power supplies. The single-slot design and the 193 mm (7.6 inches) length ensure compatibility with most chassis. The PCIe 2.0 x16 interface is the connection standard.
For gaming, the card's 480.0 GFLOPS of FP32 compute, 6.000 GPixel/s pixel rate, and 24.00 GTexel/s texture rate suggest that it is best suited to lower resolutions and reduced detail settings. The 512 MB memory and 32.00 GB/s bandwidth are the relevant constraints for texture-heavy scenes. The DirectX 10.1 (10_1) support means that games written for DirectX 10.1 or earlier can run, while newer APIs are not supported.
Users who require multiple display outputs will find the 2x DVI and 1x S-Video configuration adequate for standard setups. The card's end-of-life status means it is no longer in production, so prospective users must source it from the used market. The release date of 2008-09-09 places it in a specific hardware generation, and its successor, Evergreen, is the architectural follow-up.

How It Compares
The nearestRivals list for the ATI Radeon HD 4670 is empty, so the database provides no direct rival names, scores, or delta percentages. Consequently, the card's comparative position must be derived from its percentile ranking and its generation context.
The percentileVsAllGpus value of 50 is the only quantitative comparison available. It places the card at the median of all GPUs in the database, meaning that half of the tracked GPUs perform better and half perform worse. This is a broad, population-level comparison rather than a head-to-head rival analysis.
Within its own product lineage, the HD 4670 sits between the Radeon R600 (its predecessor) and the Evergreen architecture (its successor). The Radeon R700 (HD 4600) generation is the immediate family. The card's 59 W TDP and lack of power connectors distinguish it from higher-power parts, but the database does not list any specific rivals to compare against.
The card's own specifications provide an internal benchmark of its capabilities. The 480.0 GFLOPS FP32 throughput, 6.000 GPixel/s pixel rate, 24.00 GTexel/s texture rate, and 32.00 GB/s memory bandwidth are the measurable limits of its performance. Without rival data, these figures, combined with the 50th percentile ranking, are the best available indicators of where the HD 4670 stands.
