About ATI Radeon HD 4670 X2
The ATI Radeon HD 4670 X2, manufactured by AMD on the TeraScale architecture with the RV730 chip, holds the 50th percentile position among all GPUs in the benchmark database — a squarely mid-pack ranking. The card packs 320 shading units, 32 texture mapping units, and 8 ROPs, delivering 480.0 GFLOPS of FP32 compute, a 6.000 GPixel/s pixel rate, and a 24.00 GTexel/s texture rate. Released on 2008-09-09, it belongs to the Radeon R700 (HD 4600) generation and is now end-of-life, built on TSMC's 55 nm process with 514 million transistors on a 146 mm² die.
Benchmark Performance
The database records an average benchmark score of 0 for the HD 4670 X2, meaning no validated benchmark submissions exist in the current dataset. The 50th percentile ranking is therefore the primary performance signal: the card outperforms 50 percent of all recorded GPUs and trails the remaining 50 percent. This places it firmly in the middle of the performance distribution — not a bottom-tier part, but far from a performance leader.
The raw compute figures corroborate this mid-range positioning. FP32 throughput of 480.0 GFLOPS is the theoretical ceiling for shader work. The pixel rate of 6.000 GPixel/s and texture rate of 24.00 GTexel/s show a texture-to-pixel ratio heavily skewed toward texture fetch, meaning the card can sample textures far faster than it can write pixels. The 8 ROPs are the limiting factor for pixel output, a common constraint in mid-range cards of this generation. Texture-heavy scenes would therefore fare better than those dominated by fill-rate demands.
The manufacturing context reinforces the picture. The 55 nm process, 514 million transistors, and 146 mm² die size yield a transistor density of 3.5M / mm², reflecting the lithography of the era. With a 118 W TDP, the card's performance-per-watt is consistent with its mainstream positioning. The 50th percentile standing, combined with the compute and fill-rate metrics, indicates a card designed for mainstream 3D workloads rather than enthusiast gaming.
Who Should Consider It
The HD 4670 X2 is suited for users running DirectX 10.1-era games at modest settings. Its 320 shading units and 480.0 GFLOPS of compute are adequate for titles from its release period, but the 512 MB frame buffer is the binding constraint. Gamers who favor lower resolutions and reduced texture quality will find the card serviceable; those expecting high-detail gaming on modern titles will not.
The card's 4x DVI outputs make it a viable option for multi-monitor productivity setups. The 50th percentile performance is sufficient for 2D desktop work, video playback, and light 3D applications. The lack of Vulkan support and the DirectX 10.1 (10_1) API ceiling limit its utility for contemporary software. Users building retro gaming rigs or period-correct systems from the late-2000s era are the primary audience.
The 22.40 GB/s memory bandwidth and 128-bit bus width are adequate for the card's compute capability, but the 512 MB capacity will cause texture swapping in memory-intensive scenes. Users should plan to run games with reduced texture detail and lower resolution settings. The card is not recommended for modern AAA titles, as the feature set and memory configuration are firmly rooted in its 2008-09-09 release era.
How It Compares
The nearestRivals field in the database is empty, so no direct competitor comparisons with percentage deltas are available for the HD 4670 X2. The product lineage, however, provides context. The predecessor is the Radeon R600 series, and the successor is the Evergreen family. The card sits within the Radeon R700 (HD 4600) generation, which is consistent with its 50th percentile mid-pack ranking.
Without rival benchmark data, the comparison must rely on internal specifications. The 480.0 GFLOPS FP32 throughput, 6.000 GPixel/s pixel rate, and 24.00 GTexel/s texture rate define the card's capability envelope. The 118 W TDP and 300 W suggested PSU rating indicate a moderate power footprint relative to the performance on offer. The empty nearestRivals list means the database currently has no validated comparison points, a situation that may change as more historical GPUs are added to the database.

Ray Tracing and Feature Set
The HD 4670 X2 has no ray tracing cores and no tensor cores — both fields are null in the database. This is consistent with the TeraScale architecture, which predates hardware ray tracing by more than a decade. The feature set is defined by its API support: DirectX 10.1 (10_1) and OpenGL 3.3, with no Vulkan support. This means modern Vulkan-based titles and applications are not compatible with the card.
The DirectX 10.1 (10_1) feature level is the highest API supported, which limits the card to games and applications designed for that era. OpenGL 3.3 provides a moderately modern feature set for its time. The 4x DVI display outputs are the only connectivity options listed in the database, with no HDMI or DisplayPort support documented. The absence of tensor cores means no AI acceleration features, and the absence of RT cores means no hardware-accelerated ray tracing — features that would not appear in GPUs until much later generations.
Power and Cooling
The HD 4670 X2 has a TDP of 118 W, a moderate power draw for a dual-slot card of its generation. The suggested power supply rating is 300 W, which accounts for the system-level power requirements including the CPU and other components. The card requires a 6-pin power connector, a standard configuration for mid-range GPUs of the late-2000s.
The dual-slot form factor is an important consideration for chassis compatibility. The PCIe 2.0 x16 bus interface provides the connection to the motherboard, and the 55 nm process with 514 million transistors on a 146 mm² die determines the thermal density. The 118 W TDP is the thermal design power that the cooling solution must dissipate, and the dual-slot cooler is designed to handle this load. Users should ensure their power supply has a 6-pin PCIe power connector and a rated capacity of at least 300 W.
Memory Subsystem
The HD 4670 X2 is equipped with 512 MB of GDDR3 memory operating at 700 MHz, or 1400 Mbps effective. The 128-bit memory bus delivers a bandwidth of 22.40 GB/s. This memory configuration is the card's most significant limitation for high-resolution gaming. At 512 MB, the frame buffer can be exhausted by high-resolution textures, causing performance degradation in memory-intensive scenes.
The 22.40 GB/s bandwidth is determined by the 128-bit bus width and the 700 MHz memory clock. The GDDR3 memory type was standard for the era, and the 1400 Mbps effective data rate is achieved through double data rate signaling. For the card's 480.0 GFLOPS compute capability, the memory bandwidth is often the limiting factor, particularly at higher resolutions where pixel fill and texture fetch demands increase. The 512 MB capacity is the most restrictive element — users running games at higher resolutions with detailed textures will encounter the frame buffer limit quickly, making lower resolution and reduced texture quality settings necessary for smooth performance.
