About ATI Radeon X1900 XTX
The ATI Radeon X1900 XTX is a GPU record listed under AMD, built around the R580 chip and the Ultra-Threaded SE architecture. It belongs to the Radeon R500 PCIe (X1900) generation; the database fields for series and codename are empty. The chip was manufactured by TSMC on a 90 nm process. The die contains 384 million transistors and measures 352 mm², yielding a transistor density of 1.1M / mm². The release date is 2006-01-23, the launch MSRP is 399 USD, and the production status is end-of-life. The board is dual-slot, 242 mm / 9.5 inches long, with a PCIe 1.0 x16 interface, a 1x 6-pin power connector, a 135 W TDP, and a 300 W suggested PSU. Display outputs are 2x DVI and 1x S-Video. The memory clock is the only clock listed; base, boost, and game clocks are null. The shading-unit, FP32, and FP16 fields are also null.
Memory Subsystem
Memory capacity is 512 MB of GDDR3 on a 256-bit bus. The memory clock is 775 MHz, with an effective data rate of 1550 Mbps. That configuration produces 49.60 GB/s of bandwidth. The record also lists 16 TMUs and 16 ROPs. These yield a texture rate of 10.40 GTexel/s and a pixel rate of 10.40 GPixel/s. For high-resolution workloads, the 512 MB frame buffer is the on-card storage limit for geometry, texture, and framebuffer data, and the 49.60 GB/s bandwidth is the maximum rate at which that data can cross the memory bus. The 256-bit bus width is the physical path that supports that transfer rate. The data does not include resolution-specific benchmarks, so these figures are the only memory-related indicators in the record.
The memory clock of 775 MHz and the effective 1550 Mbps data rate are the only clock-domain values in the entire record; there is no base, boost, or game clock to compare. The 16 TMUs and 16 ROPs align with the 10.40 GTexel/s and 10.40 GPixel/s rates, respectively. With the shading-unit count null, the record cannot be used to calculate per-shader throughput. The frame buffer size is 512 MB, the bus width is 256 bit, and the bandwidth is 49.60 GB/s; together these are the full set of memory-subsystem numbers in the FACT PACK. No resolution-specific tests are attached, so any statement about high-resolution behavior must remain at the level of these capacity and bandwidth figures.
Ray Tracing and Feature Set
The X1900 XTX is built on the Ultra-Threaded SE architecture, but the record lists no RT cores and no tensor cores; both fields are null. The API set is DirectX 9.0c (9_3), OpenGL 2.1 in full, and OpenGL 3.0 in partial; Vulkan is not listed. No ray tracing API appears in the API list. The card's feature set also includes the PCIe 1.0 x16 bus interface, dual-slot cooling, a 1x 6-pin power connector, a 135 W TDP, and a 300 W suggested PSU. Display connectivity is 2x DVI and 1x S-Video. Physical length is 242 mm / 9.5 inches.
The lack of a Vulkan field and the absence of RT and tensor core entries mean that those acceleration features cannot be confirmed from the record. The OpenGL 2.1 full and OpenGL 3.0 partial distinction is the only partial-API note in the data. DirectX 9.0c (9_3) is the highest DirectX version listed in the record. The record's API list consists of DirectX 9.0c (9_3), OpenGL 2.1 full, OpenGL 3.0 partial, and a null Vulkan entry. There are no RT cores and no tensor cores in the data, so there is no hardware-level ray tracing or tensor acceleration to describe. The physical list is equally explicit: dual-slot width, 242 mm / 9.5 inches length, PCIe 1.0 x16 bus interface, 1x 6-pin power connector, 135 W TDP, and 300 W suggested PSU.
Benchmark Performance
The benchmark portion of this record contains no entries. The benchmarks array is empty, so the database has no measured performance scores for the X1900 XTX. The average benchmark score is 0; that value is a placeholder for missing data, not a test result. The percentileVsAllGpus field assigns a value of 50, placing the card at the midpoint of the database's GPU distribution. However, because no nearest rivals are listed and no benchmark scores are attached, the percentile cannot be cross-checked against competing products. There are no deltaPct figures in the record, so there are no percentage differences to report.
The only performance figures in the benchmark section are the peak fill rates: 10.40 GPixel/s and 10.40 GTexel/s. The pixel rate is derived from 16 ROPs, and the texture rate is derived from 16 TMUs. These are peak throughput limits rather than application scores. The absence of FP32 and FP16 throughput values means those fields cannot be used for comparison. The record therefore supports statements about the memory interface and fill-rate configuration, but not about measured benchmark performance. The percentile field is not accompanied by any score in the benchmarks array, so it stands alone. The average benchmark score of 0 is listed alongside the empty benchmarks array, which is consistent with a database entry that has no results. The nearestRivals field is empty, so no competitor scores or deltaPct values can be cited. In short, the benchmark section provides a positional rank and peak fill rates, but no application-level evidence.
How It Compares
The comparison data for the ATI Radeon X1900 XTX is defined by what is absent. The nearestRivals array is empty, meaning the database entry has no rival names, no rival scores, and no deltaPct values. Consequently, no rival-by-rival comparison can be written from the FACT PACK. What the record does contain is chronological context: the predecessor is Radeon R400 PCIe and the successor is Radeon R600. These are generation boundaries, not benchmark competitors. The only quantitative placement is the 50th percentile among all GPUs in the database. That rank places the card at the middle of the database distribution, but the 0 average benchmark score offers no measured performance to support that rank.
The physical attributes in the record define the installation footprint: dual-slot width, 242 mm / 9.5 inches length, 135 W TDP, a 1x 6-pin power connector, a 300 W suggested PSU, and a PCIe 1.0 x16 interface. The predecessor and successor are Radeon R400 PCIe and Radeon R600, respectively, but neither is accompanied by benchmark scores in the record. The X1900 XTX is therefore bracketed by generation, not by performance. The 50th percentile rank is the only comparative statistic in the data. It is a database-level placement, not a measurement against a named rival. In the absence of nearestRivals entries, the X1900 XTX can be positioned only by its lineage, its 50th percentile database rank, and its listed physical characteristics.
