ATI Mobility Radeon X1300

The ATI Mobility Radeon X1300 is an entry-level mobile graphics processor from AMD, built on the M52 chip using the Ultra-Threaded SE architecture. Manufactured by TSMC on a 90 nm process, this end-of-life part integrates 107 million transistors on a 100 mm² die, yielding a transistor density of 1.1M per mm². With no benchmark scores recorded and a 50th percentile ranking among all GPUs, the data positions this part strictly as a basic solution for its generation, not a performance contender.

How It Compares

The FACT PACK lists no nearest rivals, no benchmark scores, and no percentile deltas against other specific GPUs. Consequently, a direct quantitative comparison against named competitors is not possible from the available data. What can be stated is that the X1300 holds a median percentile position (50th) across all GPUs, indicating it sits exactly in the middle of the historical performance distribution when considering the entire database of graphics processors.

Without rival data, the analysis must rely on the absolute specifications provided. The pixel rate of 1.568 GPixel/s and texture rate of 1.568 GTexel/s are identical, which points to a balanced design where each of the 4 ROPs and 4 TMUs processes one operation per clock cycle at the memory clock. This symmetry is typical of low-end parts. The lack of any benchmark entries in the FACT PACK further confirms that this GPU was not intended for measured performance comparisons; its role was purely functional.

Given the absence of nearestRivals data, position statements must be framed qualitatively. The X1300 is a predecessor to the M6x series and a successor to the M2x series, placing it in the middle of the M5x generation timeline. Its 64 MB memory capacity and 64-bit bus width are the smallest configuration possible for a discrete mobile GPU of that era, suggesting it competed at the absolute bottom tier, likely against integrated graphics rather than other discrete parts.

Ray Tracing and Feature Set

The ATI Mobility Radeon X1300 has no dedicated ray tracing cores and no tensor cores, as indicated by the null values in the FACT PACK. The architecture does not support any form of hardware-accelerated ray tracing, which is consistent with its DirectX 9.0c (9_3) API support. This GPU predates the introduction of ray tracing acceleration by over a decade, so any ray-traced workloads would be entirely software-based and impractical.

The feature set is defined by its API support: DirectX 9.0c with shader model 9_3 and OpenGL 2.1. There is no Vulkan support listed, which further limits its modern compatibility. The Ultra-Threaded SE architecture was AMD's unified shader approach for that generation, but without core counts or shading unit data in the FACT PACK, the compute capabilities cannot be quantified. The DirectX 9_3 feature level indicates support for pixel shader 3.0 and vertex shader 3.0, which was standard for mid-2000s games.

The memory clock of 300 MHz (600 Mbps effective) with DDR type memory and a 64-bit bus width yields 4.800 GB/s of bandwidth. This bandwidth figure is the primary constraint on the feature set, as it limits texture fetching and framebuffer operations. The 4 TMUs and 4 ROPs are directly tied to the pixel and texture rates of 1.568, which means the GPU can fill or texture one pixel per clock per unit. This is a minimal configuration, suitable only for legacy DirectX 9 titles at low resolutions and detail settings.

Who Should Consider It

Benchmark results are absent, but the hardware specifications define a clear usage envelope. The 64 MB VRAM and 4.800 GB/s bandwidth are the deciding factors. At 800×600 or 1024×768 resolution, this GPU could handle games from the DirectX 9.0c era (circa 2004-2006) at low to medium settings, provided the frame buffer demands stay within 64 MB. Texture-heavy titles or those requiring more than 64 MB of video memory would either fail to load or experience severe stuttering due to memory swapping.

The 50th percentile ranking, while not a performance score, suggests that the X1300 is not the worst GPU ever made, but it is also nowhere near average for its time. For 1280×800 or higher resolutions, the 4.800 GB/s bandwidth becomes a hard bottleneck. Modern applications, even those that can run on OpenGL 2.1, would be impractical due to the lack of Vulkan support and the minimal memory footprint.

This GPU is only viable for users running legacy operating systems and software from the 2003-2006 timeframe. It is not suitable for any contemporary gaming, video playback beyond standard definition, or GPU-accelerated computing. The absence of FP32 and FP16 throughput figures in the FACT PACK indicates that these metrics were either negligible or not measured, reinforcing the notion that this part has no compute role.

Power and Cooling

The FACT PACK lists no TDP, no power connector requirements, and no suggested PSU wattage. The absence of this data means the power draw cannot be quantified. However, the 90 nm process node and the modest specifications—4 TMUs, 4 ROPs, 64-bit memory interface—strongly suggest a very low power envelope. A mobile GPU from this era with these specs would typically draw well under 20 W, but since no number is provided, no specific figure can be cited.

Cooling requirements are likewise unspecified. The lack of a slot width and dimensions fields implies this is a mobile chip, not a desktop card, so it would use a passive heatsink or small fan as part of a laptop cooling solution. The bus interface is PCIe 1.0 x16, which is a standard slot that provides up to 75 W from the motherboard, but the X1300 would draw far less than that limit. No auxiliary power connectors are listed, indicating the card, if it existed as a standalone product, would rely solely on slot power.

Given the production status is end-of-life and the release date is January 2006, the hardware is obsolete. Users handling such a device today must account for aging capacitors and thermal interface material degradation. The absence of a suggested PSU means any modern power supply with a PCIe slot would technically suffice, but the lack of a TDP figure prevents any meaningful recommendation.

FAQ

A: No. The FACT PACK lists no TDP, no power connectors, and no suggested PSU. The bus interface is PCIe 1.0 x16, which carries its own power limits.

Memory Subsystem

The memory subsystem is the most defining characteristic of the ATI Mobility Radeon X1300. It consists of 64 MB of DDR memory operating at 300 MHz, with an effective data rate of 600 Mbps. The 64-bit bus width is the narrowest discrete memory interface available, and when combined with the DDR data rate, it produces a total bandwidth of 4.800 GB/s.

This bandwidth figure is critically low by any modern standard. For high-resolution rendering, the bandwidth dictates how much texture data and framebuffer information can be moved per second. At 4.800 GB/s, the GPU can sustain a 1024×768 framebuffer at 32-bit color (about 3.15 MB per frame) at roughly 150 frames per second for pure framebuffer writes, but real-world workloads require texture reads, depth buffer operations, and shader data, which quickly saturate the 64-bit interface.

The 64 MB capacity is another hard limit. Textures larger than 64 MB cannot be stored locally, forcing the GPU to stream them from system memory over the PCIe 1.0 x16 bus, which is far slower than the 4.800 GB/s local bandwidth. For high-resolution gaming, 64 MB is insufficient for any modern title, and even for DirectX 9 games from the release era, it limits texture resolution to 1024×1024 or smaller with reduced mipmap levels. The pixel rate of 1.568 GPixel/s and texture rate of 1.568 GTexel/s are directly constrained by this memory throughput; the 4 ROPs and 4 TMUs cannot operate at full speed when the memory bus is the bottleneck.
