AMD Phenom II X4 940 BE

The AMD Phenom II X4 940 BE is a desktop processor from AMD, built on the K10 architecture under the Deneb codename and the Phenom II X4 generation. GlobalFoundries manufactured it on a 45 nm process with 758 million transistors on a 258 mm² die. It has four cores, four threads, a 3.00 GHz base clock, and no boost clock listed. The multiplier is unlocked, and the market segment is desktop. Its production status is end-of-life, with a release date of 2009-01-07. The database record contains comprehensive specifications, but the benchmark records themselves are empty.

Benchmark Performance

The benchmark section of this data is unpopulated. The average benchmark score field is listed as 0, and the nearestRivals array is empty. Because there are no benchmark scores, there are no deltaPct values to compare against other CPUs. The only aggregate positional data available is the percentileVsAllCpus field, which places the processor at the 50th percentile across all CPUs in the database. That rank indicates a midpoint placement in the overall distribution, but there is no underlying average score to corroborate it and no nearest-rival list to explain how that position was reached.

Without nearest rivals, exact percentage leads or deficits cannot be reported. The data does not name a single competitor, so no statement such as “X% ahead of” or “X% behind” can be grounded in the FACT PACK. What the data does provide is a fixed 3.00 GHz base clock and no boost clock, meaning the specification sheet offers no higher turbo frequency to consider. The cache configuration is complete: 128 KB of L1 cache per core, 512 KB of L2 cache per core, and 6 MB of shared L3 cache.

Because the benchmark array is empty, the 50th percentile should be interpreted cautiously. It is the only performance-positioning number in the record, but it is not backed by individual workload scores or rival comparisons. The practical takeaway from the benchmark data is limited: the CPU sits at the middle of the reference sample, and the database contains no measured deltas to drill into.

Platform and Compatibility

The Phenom II X4 940 BE uses AMD Socket AM2+. Memory support is DDR2, configured through a dual-channel memory bus with a listed bandwidth of 17.1 GB/s. ECC memory is supported, which is a notable feature for a desktop processor and points toward memory-error-sensitive workloads. PCIe support is Gen 2. Integrated graphics are not part of the CPU itself; the data lists integrated graphics as a chipset feature available on certain motherboards. This means display output depends on the motherboard chipset or a discrete graphics card.

The platform’s upgrade path is defined by the socket and memory support. AM2+ motherboards are the compatible socket type, and the memory controller is DDR2-only. The processor is end-of-life, so the data does not describe it as an actively produced part. The release date of 2009-01-07 places the platform in the DDR2/PCIe Gen 2 era. The part number given is HDZ940XCJ4DGIHDZ940XCGIBOX. The launch MSRP was $275.

For anyone considering this processor, the platform limitations are clear: AM2+ and DDR2 are the boundaries of the system. The CPU supports four cores and four threads, so the motherboard must be able to feed a quad-core K10 Deneb processor. PCIe Gen 2 is the available interconnect generation. ECC support may require a motherboard that specifically supports ECC DDR2, although the database does not name specific board models. The integrated graphics situation on certain motherboards via the chipset is a platform feature rather than a CPU feature.

How It Compares

The nearestRivals field is empty, so there are no rival names, no rival scores, and no deltaPct values to cite. There is no individual competitor to place against the Phenom II X4 940 BE in this database record. The only positional data point is the 50th percentile among all CPUs, which places it at the exact midpoint of the database’s overall CPU distribution. That midpoint does not reveal the distance to the next CPU in either direction, nor does it identify whether the adjacent parts are AMD or Intel processors.

Because the nearestRivals array is empty, no comparison paragraphs can be written for specific rival processors. The data does not support a claim that this processor beats or trails any named model. Any comparative statement from another source would be external to the FACT PACK and cannot be confirmed through this record. The safest summary is that the database has not assigned nearest rivals to this part, and therefore its competitive position is expressed solely by the broad 50th percentile rank.

Q: What is the launch MSRP?

A: The launch MSRP was $275.

Power and Thermals

The TDP is 125 W. This is the only thermal specification in the data. A 125 W TDP places the processor in a cooling class that requires a capable heatsink and fan solution; it is not a low-power part. The data does not list a bundled cooler, so the 125 W figure is the reference point for choosing a cooling solution.

The underlying process data is relevant to thermals as well. The processor is built on a 45 nm process by GlobalFoundries, with 758 million transistors on a 258 mm² die. The base clock is 3.00 GHz, and no boost clock is listed, so the CPU does not have a higher automatic turbo frequency in the specification sheet. The unlocked multiplier is present, which means overclocking is possible, but the data does not include any overclocked TDP figures. Under stock operation, the 125 W TDP is the rating that a cooling solution must address.

Who Should Consider It

This processor suits builds where four cores and four threads are enough. The 3.00 GHz base clock is the only operating frequency listed, and there is no boost clock to provide burst performance. That makes it a predictable choice for workloads that rely on a fixed core clock. The cache hierarchy, with 128 KB L1 per core, 512 KB L2 per core, and 6 MB shared L3, provides a complete structure for repeated data access, which matters for multithreaded and data-heavy tasks.

The unlocked multiplier makes the processor attractive to overclockers who have an AM2+ motherboard capable of supporting the 125 W TDP class. ECC memory support expands the potential use cases to memory-sensitive work, although the memory bus is DDR2 with 17.1 GB/s bandwidth. The lack of integrated graphics on the CPU means a discrete GPU is usually required, unless the motherboard chipset provides graphics as indicated in the data.

Given the 50th percentile overall rank, the processor sits in the middle of the database’s CPU distribution. The workloads it fits best are those that can use four threads and benefit from a 3.00 GHz base clock, a shared 6 MB L3 cache, and dual-channel DDR2 memory. Office, general-purpose desktop, and memory-integrity-conscious tasks align with the published specifications. Users expecting high core counts, fast automatic boosting, or modern memory support will not find those features in this data, because the processor has four threads, no boost clock, and DDR2 support only.
