About ATI Radeon HD 4720
The ATI Radeon HD 4720 is an entry-level graphics card from AMD, built on the 55 nm TeraScale architecture with the RV730 chip. It features 320 shading units, 32 texture mapping units, and 8 ROPs, paired with 1024 MB of GDDR3 memory on a 128-bit bus, delivering a memory bandwidth of 21.34 GB/s. Its modest specifications place it in the mid-low tier of the performance spectrum, evidenced by its 50th percentile ranking among all GPUs.
Benchmark Performance
The benchmark data for the ATI Radeon HD 4720 is notably sparse, with no synthetic or real-world test scores recorded in the current database. Its average benchmark score is listed as 0, which offers no direct numerical comparison to other cards. However, the 50th percentile ranking against all GPUs provides a meaningful positional anchor. This percentile indicates that the HD 4720 sits exactly at the median of the entire GPU landscape, meaning it outperforms half of all graphics cards ever released while being outperformed by the other half. For context, this places it well above integrated graphics solutions that typically occupy the lower quartiles, but far below any modern discrete GPU.
The card’s theoretical compute metrics offer a clearer picture of its raw capabilities. The FP32 performance is rated at 384.0 GFLOPS, which is a modest figure for its generation. Its pixel fill rate of 4.800 GPixel/s and texture fill rate of 19.20 GTexel/s further underscore its limited throughput. These numbers suggest that the HD 4720 was designed for 720p gaming at low to medium settings in its era, not for high-resolution or high-refresh-rate workloads. With 8 ROPs, the card is heavily constrained in pixel processing, which directly impacts its ability to handle modern games that demand higher fill rates. The 32 TMUs, while adequate for the core count, do not compensate for the ROP limitation in texture-heavy scenes.
How It Compares
The FACT PACK lists no nearest rivals for the ATI Radeon HD 4720, leaving a gap in direct comparative analysis. This absence is itself informative, as it suggests the card occupies a niche position with no close competitors in the current database’s tracking. Historically, the HD 4720 would have competed with other entry-level offerings of its time, but without specific rival scores or deltaPct values, any such comparison would be speculative. What can be stated is that its 50th percentile standing puts it in a crowded field of mid-low tier cards, where performance differences of a few percent often decide market placement. The lack of rival data means the HD 4720’s relative strengths—such as its 55 nm process efficiency—cannot be quantified against specific alternatives. The card’s predecessor, the Radeon R600 series, and its successor, the Evergreen architecture, bracket its generation, but no performance deltas are provided for either.
Ray Tracing and Feature Set
The ATI Radeon HD 4720 does not include any dedicated ray tracing or tensor cores, as these technologies were not introduced into AMD’s consumer lineup until much later generations. This card is built on the TeraScale architecture, which predates the compute-centric designs of modern GPUs. Consequently, any ray tracing workload would be entirely unsupported in hardware, and software-based implementations would be impractical given the card’s 384.0 GFLOPS FP32 throughput. The absence of these cores is a defining limitation, making the card unsuitable for any modern rendering pipeline that relies on accelerated ray tracing.
In terms of API support, the HD 4720 is limited to DirectX 10.1 (feature level 10_1) and OpenGL 3.3. It does not support Vulkan, which is a significant drawback for contemporary gaming, as most modern titles require at least DirectX 11 or Vulkan for optimal functionality. The DirectX 10.1 support means the card can run games built for that API, but it will fail to launch or exhibit severe graphical glitches in titles that mandate DirectX 11 or 12. OpenGL 3.3 is similarly aged, limiting compatibility with modern emulators or professional applications that require newer OpenGL versions. This feature set firmly locks the HD 4720 into legacy use cases, such as running older Windows XP/Vista-era games or serving as a basic display adapter for non-gaming tasks.
Who Should Consider It
Given its 50th percentile ranking and the lack of benchmark scores, the ATI Radeon HD 4720 is only suitable for a very specific audience: those running legacy software from its release era around late 2011. The card’s 1024 MB of GDDR3 memory and 21.34 GB/s bandwidth are sufficient for 720p resolutions at low detail settings in games released before 2010. For example, titles from the DirectX 9 and early DirectX 10 era would be playable, provided the user is willing to accept frame rates below 30 FPS in demanding scenes. The card’s 4.800 GPixel/s pixel rate becomes a bottleneck at higher resolutions, so 1080p gaming is not recommended unless the user is playing very lightweight 2D or indie titles.
At 720p with low settings, the HD 4720 could deliver playable performance in older strategy games, MMORPGs, or console ports from the early 2000s. However, the card’s 8 ROPs and 19.20 GTexel/s texture rate will struggle with any game that uses modern post-processing effects or high-resolution textures. The absence of DirectX 11 support also excludes a vast library of games from 2010 onward, including popular titles like Civilization V or Battlefield 3, which require DX11 for full functionality. Users considering this card today should have a specific need for a low-power, single-slot PCIe 2.0 x16 adapter with legacy DVI or S-Video outputs, rather than a gaming performance expectation. Its 50th percentile status means it is not the worst card available, but it is far from capable of handling modern workloads.
Power and Cooling
The ATI Radeon HD 4720 has a thermal design power (TDP) of 55 W, which is exceptionally low by modern standards. This low power draw means the card can be cooled by a simple single-slot heatsink and fan design, as indicated by its single-slot form factor. The suggested power supply unit (PSU) rating is 250 W, which is another indicator of its efficient power profile. A 250 W PSU is common in older or budget office systems, making the HD 4720 a drop-in replacement for integrated graphics in such machines, provided the PSU has a spare PCIe power connector. However, the FACT PACK does not list any power connectors for this card, which suggests it may draw all its power solely from the PCIe 2.0 x16 slot, further simplifying installation.
The card’s physical dimensions are 193 mm (7.6 inches) in length, which is compact enough to fit in most standard mid-tower cases, though the single-slot design is beneficial for small form factor builds. The lack of a power connector requirement minimizes cable management needs, making installation straightforward. The 55 W TDP also means that the card generates minimal heat, so a case with basic airflow will suffice; no additional cooling considerations are necessary. This power efficiency is a double-edged sword: while it enables quiet operation and low energy costs, it also caps the card’s performance ceiling, as the 55 W budget must be shared across the 320 shading units, memory controller, and display outputs. For users with a 250 W PSU and a need for a legacy display output (2x DVI and 1x S-Video), this card is a functional, low-risk option, but it offers no headroom for overclocking or future upgrades.
