NVIDIA GeForce2 MX + nForce 420

The NVIDIA GeForce2 MX + nForce 420 is an end-of-life integrated graphics part built around the Crush11 chip and the Celsius architecture. It belongs to the GeForce 2 MX IGP generation, uses a 180 nm process, contains 20 million transistors on a 65 mm² die, and has a transistor density of 307.7K / mm². The product provides 4 TMUs and 2 ROPs, with a pixel rate of 350.0 MPixel/s and a texture rate of 700.0 MTexel/s. It relies entirely on system shared memory, connects through AGP 4x, and was released on 2001-06-03. Its successor is the GeForce 4 MX IGP. The database record contains no benchmark entries, no nearest rival entries, and an average benchmark score of 0; the only ranking value is the 50th percentile among all GPUs.

Who Should Consider It

The data describes a motherboard-integrated solution rather than a standalone expansion card: the slot width is IGP and the display outputs are motherboard dependent. Any system built around this part has no fixed video memory capacity to plan around, because memory size, memory type, memory bus width, and memory clock are all listed as system shared. The practical effect is that graphics memory capacity and bandwidth are determined by the host system. The bandwidth field makes this explicit: it is “System Dependent.” That means no single memory bandwidth figure can be applied to every configuration.

For resolution and settings planning, the empty benchmark array and zero average score mean no score-derived frame-rate guidance exists. The usable quantitative limits are 350.0 MPixel/s for pixel throughput and 700.0 MTexel/s for texture throughput. These values indicate a part that is more suitable for lower resolutions and lighter texture workloads than for high resolutions or heavy texture filtering. The API set reinforces the same expectation: DirectX 7.0 and OpenGL 1.2 are the only listed APIs, and Vulkan is absent. Therefore, the likely audience is a system targeting software from the DirectX 7.0 / OpenGL 1.2 era and not requiring newer graphics features. The end-of-life status and the 2001 release date further indicate a product whose practical relevance is tied to older platforms.

How It Compares

The nearestRivals list in the FACT PACK is empty. There are no rival names, no rival scores, and no deltaPct values for this product. Consequently, the record cannot express performance relative to any named alternative. The only comparative value is the percentileVsAllGpus figure of 50, which places the GeForce2 MX + nForce 420 at the midpoint of the all-GPU distribution. That percentile is not supported by a non-zero average benchmark score; the benchmarks array is empty and the average benchmark score is 0. Without benchmark scores, deriving a percentage lead or deficit is impossible. The comparison story for this record is the absence of measured comparison data.

Ray Tracing and Feature Set

The FACT PACK lists null values for rtCores and tensorCores, so there is no dedicated ray tracing core count and no tensor core count to report. The feature set that is present centers on the Celsius architecture and the Crush11 IGP chip. The manufacturing details include a 180 nm process, 20 million transistors, a 65 mm² die, and a transistor density of 307.7K / mm². The fixed-function pipeline is defined by 4 TMUs and 2 ROPs, producing 350.0 MPixel/s and 700.0 MTexel/s. On the API side, DirectX 7.0 and OpenGL 1.2 are explicitly listed, while Vulkan is not. No shading unit count is listed, and the FP32 and FP16 throughput fields are null, so the record supports no compute-throughput claims. The null RT and tensor core fields similarly provide no basis for ray-traced or tensor-accelerated workload claims.

FAQ

Q: How much memory does the GeForce2 MX + nForce 420 have?

A: There is no dedicated memory capacity in the record. Memory size, memory type, and memory bus width are all listed as “System Shared.” Bandwidth is “System Dependent,” and the memory clock is also “System Shared.”

Q: Does it support ray tracing?

A: No ray tracing core count is present; the rtCores field is null. The tensorCores field is also null. The listed APIs are DirectX 7.0 and OpenGL 1.2, with no Vulkan entry.

Q: What processor technology is used?

A: The chip is Crush11, and the architecture is Celsius. It is manufactured on a 180 nm process with 20 million transistors and a 65 mm² die, giving a transistor density of 307.7K / mm².

Q: What is the successor to this product?

A: The successor is the GeForce 4 MX IGP. No predecessor is listed in the FACT PACK.

Q: What APIs does it support?

A: It supports DirectX 7.0 and OpenGL 1.2. The Vulkan field is null, so no Vulkan support is indicated.

Q: What is the bus interface and display output configuration?

A: The bus interface is AGP 4x. The display outputs are “Motherboard Dependent,” meaning the motherboard determines the available display connectors.

Benchmark Performance

The benchmarks array is empty, and the average benchmark score is 0. This makes the 50th percentile difficult to interpret as a measured performance rank; it is a position in the distribution, but it is not backed by any actual benchmark average. The only quantitative performance indicators in the record are the raw throughput rates of 350.0 MPixel/s and 700.0 MTexel/s. With 4 TMUs and 2 ROPs, those rates bound the pixel-fill and texturing work the part can perform per second. No base, boost, or game clock values are listed, so the pixel and texture rates serve as the primary throughput figures. There are no nearestRivals objects, so there are no exact deltaPct values to cite. A statement that this part is a specific percentage faster or slower than a named product cannot be made from this record. The zero average score and empty benchmark list also rule out benchmark-derived comparisons beyond the single 50th-percentile field. In short, the benchmark section of this record contains no measured performance data; the only defensible performance analysis uses the listed pixel rate and texture rate.

Memory Subsystem

The memory subsystem is entirely system shared. The memory size field, the memory type field, and the memory bus width field all read “System Shared.” The bandwidth field reads “System Dependent,” which means no fixed bandwidth figure can be quoted for this part. There is no dedicated frame buffer and no dedicated memory bus width. This matters for high resolutions because any increase in resolution or texture work must draw on the same system memory resources used by the rest of the platform. Because bandwidth is system dependent, each host platform will present a different memory configuration. The memory clock is also listed as “System Shared,” reinforcing that no on-card memory timing is specified. The AGP 4x bus interface is the defined path to the system, but the actual behavior of that path depends on the memory architecture of the motherboard. Therefore, the FACT PACK can confirm that high-resolution behavior will be tied to the platform, but it cannot quantify that behavior.

Power and Cooling

The TDP field is null, the suggested PSU field is null, and the power connectors field is null. No power draw figure, no power supply recommendation, and no connector requirement appear in the record. The slot width is listed as IGP, indicating an integrated processor rather than an expansion card. As an IGP, it does not carry its own power connector in the way a discrete add-in board might. The display outputs are motherboard dependent, and the physical integration means the motherboard determines the thermal environment. Because no TDP is provided, this record cannot state a thermal power requirement or validate a specific cooling solution. The absence of a suggested PSU is consistent with an IGP that is not specified as a standalone card.
