ATI Radeon X1600 XT

The ATI Radeon X1600 XT is a PCIe 1.0 x16 graphics card from AMD, built around the RV530 chip and the Ultra-Threaded SE architecture. It is manufactured on TSMC's 90 nm process with 157 million transistors on a 150 mm² die, giving a transistor density of 1.0M/mm². The card carries 256 MB of GDDR3 memory on a 128-bit interface, with a memory clock of 690 MHz / 1380 Mbps effective and a bandwidth of 22.08 GB/s. The database record lists an average benchmark score of 0, an empty nearestRivals list, and a 50th-percentile ranking among all GPUs.

Benchmark Performance

The benchmark record for the X1600 XT does not include any sampled frame-rate or compute scores. The average benchmark score is logged as 0, and the nearestRivals field is empty. Because no rival entries are associated with the card, exact percentage deltas cannot be reported. The sole comparative metric is the 50th-percentile placement, which positions it at the median of the GPU pool stored in the database.

Without measured scores, the fill-rate figures are the strongest performance indicators available. The card sustains a pixel rate of 2.360 GPixel/s and a texture rate of 2.360 GTexel/s, both produced by 4 ROPs and 4 TMUs. The equality of these two rates means the pixel pipeline and texture pipeline are paced identically; neither stage has an obvious raw throughput advantage over the other. For a DirectX 9.0c (9_3) and OpenGL 2.1 part, that balance matters because scene complexity tends to tax texturing and pixel fill together. The two rates therefore describe a single hard ceiling rather than a lopsided configuration.

The memory clock is the only clock figure recorded. It is 690 MHz, or 1380 Mbps effective. That clock feeds 22.08 GB/s of bandwidth over the 128-bit bus. The bandwidth is sufficient to keep the 2.360 GPixel/s and 2.360 GTexel/s rates fed for simple color writes, but high-resolution texture access can saturate the bus more quickly. The database does not provide FP32 or FP16 throughput values, and the shading unit count is null, so shader-workload performance cannot be derived from the available data.

Given the absence of measured scores, the 50th-percentile rank is a position without a magnitude. It places the card in the middle of the database's GPU distribution, but it does not show by how much it trails leaders or leads laggards. A reader should treat the card as a median-performance device in this database universe, with the fill-rate and bandwidth numbers as the only concrete performance limits.

Who Should Consider It

The X1600 XT suits systems that need DirectX 9.0c (9_3) output through a PCIe 1.0 x16 slot. The display outputs cover a practical range of connection types: 1x DVI, 1x VGA, and 1x S-Video. Since the card has no listed auxiliary power connectors, it fits into systems where no extra PCIe power cable exists.

The memory side defines the practical workload. With 256 MB of GDDR3, the frame buffer is the primary constraint for resolution-heavy use. At high resolutions, geometry, color buffers, depth data, and textures must all reside within 256 MB. Titles that need more than that capacity will stream from system memory or lower detail. The 22.08 GB/s bandwidth is the ceiling for that streaming. Users should plan for high-detail 3D scenes at moderate resolutions, or reduced detail at higher resolutions, rather than maximum settings.

The 2.360 GTexel/s texture rate limits heavy texture-filtering work. The 4 TMUs and 4 ROPs suggest a narrow execution width for the era, and the equal pixel and texture rates reinforce that impression. The card is therefore more credible for lighter 3D applications and older shader-era software than for scenes that demand large texture batches. No benchmark scores are present to validate resolution-specific settings, so any recommendation must be grounded in the hardware limits: 256 MB of VRAM, 22.08 GB/s of bandwidth, and fill rates of 2.360 GPixel/s and 2.360 GTexel/s.

Power and Cooling

The TDP is listed at 42 W. The suggested PSU rating is 200 W. The power connector field is "None," so the card does not require a dedicated PCIe power cable. The slot width is single-slot, and the bus interface is PCIe 1.0 x16.

Because no external power connector is listed, all operating power is expected to come through the motherboard slot. The 42 W TDP is the only power-draw figure in the record; no current draw is given. The 200 W suggested PSU is the database's recommended system power level, not a measured consumption number.

Cooling is only partly documented. The card is single-slot, but no fan, heatsink, or cooler-size details are included. Likewise, dimensions for length, height, and width are null. Physical fit beyond the single-slot designation and the absence of power connectors is therefore not established by the data.

How It Compares

The nearestRivals field is empty, so there are no named competitors for the X1600 XT in the database. Without rival names, scores, or deltaPct values, no per-card comparison can be calculated. The only comparative data point is the 50th-percentile rank among all GPUs.

In terms of product lineage, the predecessor is Radeon R400 PCIe and the successor is Radeon R600. These are generation labels in the record, not performance comparisons. They show that the X1600 XT sits between two Radeon product stages, but they do not imply a performance advantage or disadvantage relative to either.

The empty nearestRivals list also leaves the 50th-percentile rank without context. DeltaPct values would normally describe how far above or below a rival this card sits; none exist here. Any statement that the X1600 XT is faster than one card or slower than another would be unsupported by the available data. The record simply places it in the middle of the database distribution and stops there.

Memory Subsystem

The memory configuration consists of 256 MB of GDDR3 on a 128-bit bus. The memory clock is 690 MHz, and the effective data rate is 1380 Mbps. This yields an aggregate bandwidth of 22.08 GB/s.

The 128-bit bus is a narrow path, and the 1380 Mbps effective rate is the per-pin signaling speed used to reach the aggregate bandwidth. With a smaller bus width, bandwidth is achieved through a higher effective clock rather than through more parallel lanes. The practical consequence is that the memory subsystem is balanced around 22.08 GB/s, which must serve all texture fetches, frame-buffer writes, and geometry data transfers.

At high resolutions, capacity and bandwidth operate together. The 256 MB buffer must hold the front and back color buffers, depth or stencil data, and texture working set. If the workload exceeds 256 MB, the GPU must reuse or re-upload data across the 22.08 GB/s path. This is a particular concern for high-resolution texture sets, where texture data can consume a large share of the limited 256 MB capacity.

The pixel rate of 2.360 GPixel/s further links resolution to memory pressure. As resolution rises, the number of pixels to fill increases, and the bandwidth needed to write those pixels grows with it. Texture-heavy scenes will tend to become bandwidth-bound before the pixel-fill ceiling is reached, because every texel fetched travels across the same 128-bit bus.
