ATI Mobility Radeon X2300 HD

The ATI Mobility Radeon X2300 HD is an end-of-life mobile graphics solution from AMD, built on the 80 nm TSMC process with the M71 chip. It utilizes the Ultra-Threaded SE architecture and integrates 107 million transistors on a 100 mm² die, yielding a transistor density of 1.1M per mm². Released in early 2007 as part of the M7x generation, it sits between the M6x predecessor and M8x successor lines. Its benchmark percentile ranking places it at the 50th percentile among all GPUs, indicating a strictly mid-pack historical position, though the absence of direct benchmark scores or rival data in the available records limits quantitative comparison.

Benchmark Performance

The available data for the ATI Mobility Radeon X2300 HD does not include synthetic benchmark scores, average performance figures, or a list of nearest rivals with percentage deltas. The avgBenchmarkScore field is recorded as 0, and the nearestRivals array is empty. Consequently, any precise performance analysis must rely on the hardware specifications and architectural characteristics rather than measured results. The pixel rate is 1.916 GPixel/s, and the texture rate is equally 1.916 GTexel/s, indicating a balanced design where each of the 4 texture mapping units (TMUs) and 4 render output units (ROPs) operate at the same effective throughput. This symmetry suggests that the card is not bottlenecked in either pixel shading or texture fetching at its native clock speeds.

Given the 50th percentile ranking, the X2300 HD sits exactly at the median of all GPUs tracked in the database. This implies that half of all historical graphics processors performed better, and half performed worse. However, without specific rival scores, the practical interpretation is that this was a mainstream or entry-level mobile part during its era. The lack of FP32 or FP16 throughput figures means shader performance cannot be quantified directly, but the architecture's 4 TMUs and 4 ROPs point to a design intended for casual gaming and multimedia acceleration rather than high-end 3D workloads. The DirectX support is limited to 9.0c with shader model 9_3, which places it firmly in the pre-DirectX 10 generation, capping its feature set for modern graphical effects.

Power and Cooling

The FACT PACK does not specify a thermal design power (TDP) for the ATI Mobility Radeon X2300 HD, nor does it list a suggested power supply unit (PSU) rating or power connector requirements. This absence of data is typical for a mobile GPU, where system-level power delivery is handled by the laptop manufacturer rather than an end-user PSU. The card interfaces via PCIe 1.0 x16, which provides up to 75 watts of power through the slot itself, but the actual consumption of the X2300 HD remains unquantified in the records. Given its 80 nm manufacturing process and modest specifications—4 TMUs, 4 ROPs, and a 32-bit memory bus—the power draw was likely modest by desktop standards, but no exact figure can be cited.

For cooling, the absence of slot width, length, height, or dimension data suggests this was a chip-level solution integrated onto a mobile motherboard, relying on the laptop's thermal solution. The 80 nm node was relatively mature for 2007, typically associated with moderate heat generation compared to newer processes, but again, no thermal numbers are provided. The lack of power connector details reinforces that this is not a card for desktop installation; it is a mobile part where the OEM determines the cooling and power architecture. Benchmark analysts should treat the X2300 HD as a low-power component, but the data does not support any specific wattage or cooler recommendation.

Who Should Consider It

The ATI Mobility Radeon X2300 HD, with its 256 MB of DDR2 memory and 32-bit memory bus, is not suited for modern high-resolution gaming or compute-intensive tasks. The 3.024 GB/s memory bandwidth is severely constrained—a figure that would bottleneck even light 3D workloads at resolutions above 720p. The DirectX 9.0c (9_3) API support means it cannot run titles requiring DirectX 10 or later, effectively excluding it from the vast majority of games released after 2007. For historical or legacy software, the 1.916 GPixel/s fill rate can handle simple 2D interfaces and very old 3D games at low resolutions, but the 32-bit bus width will cause significant frame pacing issues in any scene with high texture complexity.

Users who might consider this GPU are those running vintage operating systems or software from the mid-2000s, where DirectX 9.0c was the standard. At 800x600 or 1024x768 with minimal detail settings, the X2300 HD could deliver playable framerates in titles from its era, but the 256 MB VRAM would require texture quality reductions. The 50th percentile ranking confirms it was never a performance leader, even at launch. For any modern use case—web browsing with hardware acceleration, video playback beyond standard definition, or productivity suites with GPU-accelerated effects—the lack of Vulkan support and OpenGL 2.1 limit makes it unsuitable. This is strictly a collector's item or a curiosity for hardware historians, not a functional daily driver.

How It Compares

The nearestRivals array in the FACT PACK is empty, meaning no direct comparison data is available for the ATI Mobility Radeon X2300 HD against specific competing GPUs. This absence is notable because most benchmark databases populate this field with at least a few comparable parts, but the records indicate zero rivals. Consequently, the X2300 HD cannot be positioned against any specific NVIDIA or other AMD mobile solution using quantitative deltas. The 50th percentile ranking provides a general anchor, implying it performed on par with the median mobile GPU of its time, but without rival names or scores, any attempt at direct comparison would be speculative.

The predecessor and successor designations—M6x and M8x, respectively—offer generational context. The X2300 HD is part of the M7x generation, which typically represented an incremental update over M6x parts, but no performance deltas are given. The successor M8x generation would presumably offer improvements, but again, no data supports this. In the absence of rival metrics, the only defensible statement is that the X2300 HD occupied a middle-tier position in the 2007 mobile GPU landscape, as evidenced by its median percentile score. Users seeking comparative analysis will find no specific rival to benchmark against, making this entry an isolated data point in the database.

Memory Subsystem

The memory configuration of the ATI Mobility Radeon X2300 HD is one of its most defining and limiting characteristics. It features 256 MB of DDR2 memory operating at 378 MHz, which translates to 756 Mbps effective data rate. The memory bus is only 32 bits wide, resulting in a total bandwidth of 3.024 GB/s. This bandwidth figure is exceptionally low by any standard—even for 2007—and directly impacts performance at higher resolutions. For context, a 32-bit bus means that each clock cycle transfers only 4 bytes of data, which severely restricts how quickly textures and frame buffers can be accessed.

At resolutions of 1024x768 or higher, the 3.024 GB/s bandwidth becomes a primary bottleneck, as the GPU must constantly wait for memory operations to complete. The 256 MB capacity limits the size of textures and the number of buffered frames, forcing the driver to swap data aggressively. For high-resolution gaming, this effectively caps playable settings to the lowest possible levels. The combination of 4 TMUs and 4 ROPs means the chip can generate pixels and textures at 1.916 GPixel/s and 1.916 GTexel/s, but these rates are meaningless if the memory cannot feed the pipeline. The DDR2 type, while common for the era, offers lower bandwidth per pin compared to GDDR3 or GDDR4, exacerbating the narrow bus issue. Any workload that exceeds the 256 MB VRAM capacity will spill into system memory over the PCIe 1.0 x16 interface, which further degrades performance. This memory subsystem is the definitive constraint of the X2300 HD, making it unsuitable for any application requiring high data throughput.
