ATI Radeon X1600

ATI Radeon X1600 is an end-of-life AMD graphics card built on the RV516 chip with the Ultra-Threaded SE architecture. It belongs to the Radeon R500 PCIe generation, was made on UMC's 90 nm process, and integrates 105 million transistors across a 100 mm² die. The card uses a PCIe 1.0 x16 interface and occupies a single slot. The database lists an average benchmark score of 0 and an empty benchmark array; its only positional score is the 50th percentile among all GPUs.

Who Should Consider It

Because the benchmark array is empty, there is no measured performance data from which to derive resolution- or settings-specific recommendations. The 50th percentile placement is too coarse to distinguish playable settings. What the record does show is a card with a DirectX 9.0c (9_3) feature level and OpenGL 2.1 support, no Vulkan support, and a 512 MB DDR2 frame buffer on a 128-bit bus. That combination points toward older DirectX 9-oriented software rather than modern API-heavy applications. The 27 W TDP, single-slot design, and absence of power connectors make it mechanically simple to install in any PCIe 1.0 x16 slot. With 2x DVI and 1x S-Video outputs, it can drive two digital displays and one analog output. Users who need to bring an older PCIe system back to life with a low-power card are the natural audience. Users expecting benchmark-validated high-resolution performance should look elsewhere, as this card's 12.80 GB/s bandwidth and 512 MB VRAM are the data-imposed limits.

Power and Cooling

The card's TDP is 27 W. AMD's suggested PSU rating is 200 W. No power connectors are present, so no auxiliary PSU cables are needed. The single-slot design keeps chassis footprint minimal. On a 90 nm UMC process with 105 million transistors and a 100 mm² die, the 27 W figure is consistent with a low-power device. There are no power connectors to route, and the database states a 200 W PSU recommendation. That makes the card suitable for systems with modest power supplies. The transistor density is 1.1M transistors per square millimeter, which contextualizes the small die and low thermal load. Builders should verify that a spare PCIe 1.0 x16 slot is available, since the bus interface is PCIe 1.0 x16.

Ray Tracing and Feature Set

RT core and tensor core counts are not listed. This means no hardware ray tracing or tensor-based acceleration can be confirmed from the data. The available APIs are DirectX 9.0c with feature level 9_3 and OpenGL 2.1. Vulkan is null in the fact pack, so Vulkan support is absent. The feature set is therefore bound to the Radeon R500 PCIe generation and the Ultra-Threaded SE architecture. Fixed-function throughput is 2.540 GPixel/s and 2.540 GTexel/s, driven by 4 TMUs and 4 ROPs. Those rates define the card's fill-rate ceiling for DirectX 9-era workloads. Without RT cores or tensor cores, the card has no hardware blocks for ray tracing or AI-based features. Any rendering work must be handled by the traditional pixel and texture pipeline.

FAQ

Q: How much memory does the X1600 have?

A: It has 512 MB of DDR2 on a 128-bit bus, with 12.80 GB/s bandwidth and a 400 MHz memory clock running at 800 Mbps effective.

Q: What power supply does it need?

A: The suggested PSU is 200 W. The card's TDP is 27 W, and no power connectors are required.

Q: Does it support Vulkan?

A: No. Vulkan is not listed. The available APIs are DirectX 9.0c (9_3) and OpenGL 2.1.

Q: What display outputs are built in?

A: The card includes 2x DVI and 1x S-Video outputs.

Q: What is the manufacturing process?

A: It was manufactured on a 90 nm process at UMC, with 105 million transistors on a 100 mm² die.

Q: Can it do hardware ray tracing?

A: No. The database does not list RT cores or tensor cores for this card, so hardware ray tracing acceleration is absent.

How It Compares

The nearestRivals field is empty, so there are no nearest rival entries to analyze. The only comparative data point is percentileVsAllGpus: 50, which means the card is placed at the midpoint of the database's GPU distribution. The average benchmark score is 0 and the benchmarks list is empty, so no deltaPct values can be computed against any chosen rival. Without rival names or delta percentages, direct head-to-head statements are impossible. The predecessor is Radeon R400 PCIe and the successor is Radeon R600, but these are lineage facts, not nearest-rival comparison scores. No rival paragraphs follow because none are defined in the database.

Memory Subsystem

The memory subsystem is 512 MB of DDR2 on a 128-bit bus. The memory clock is 400 MHz, with an effective data rate of 800 Mbps. Total memory bandwidth is 12.80 GB/s. For high resolutions, that bandwidth is the limiting resource: each frame must fit into 512 MB, and the 128-bit path can move only 12.80 GB/s between the frame buffer and the GPU. The pixel rate of 2.540 GPixel/s and texture rate of 2.540 GTexel/s are the complementary fill-rate figures. With 4 ROPs handling pixel output and 4 TMUs handling texture fetches, the memory bus has no obvious headroom for large frame buffers. The 400 MHz memory clock and DDR2 type define the data rate ceiling. In practice, the combination of 512 MB capacity and 12.80 GB/s bandwidth means high-resolution workloads will be constrained by the memory subsystem before the 4 TMUs and 4 ROPs reach their full output.
