Intel Xeon X5472

Intel's Xeon X5472 is a quad-core server/workstation processor built on the Core 2 architecture, manufactured on Intel's 45 nm process. Codenamed Harpertown, the chip contains 820 million transistors across a dual-die package with two 107 mm² dies. It offers four cores and four threads at a fixed 3.00 GHz base clock, with no boost clock and a locked multiplier. Released on 2007-11-10, the X5472 was aimed at Intel Socket 771 platforms with dual-channel DDR2 or DDR3 memory depending on motherboard, ECC support, and PCIe Gen 2 connectivity. A 120 W TDP signals a high-power part in the server segment. In current benchmark suites, it records a Cinebench R15 multi-core score of 188, a Cinebench R20 multi-core score of 784, a Cinebench R20 single-core score of 110, a Cinebench R23 multi-core score of 1867, and a Cinebench R23 single-core score of 263. Those results place the X5472 at the 15th percentile of all tracked CPUs, with an average benchmark score of 642.

How It Compares

The average benchmark score of 642 puts the X5472 in a tightly clustered group of low-end parts. Against the Intel Celeron G3930T, the Xeon trails by 0.1%: the Celeron averages 643. That difference is trivial in aggregate testing, and the data shows two processors that would trade positions depending on the workload. The gap to the Intel Pentium G3440 is similarly narrow. The Pentium averages 644, a 0.2% advantage over the Xeon. A 0.2% delta is well within normal run-to-run variance, so the average scores do not support declaring either chip consistently faster.

The picture flips against the Intel Core i5-3437U, where the X5472 leads by 0.4% with a 642 average against 639. The nominal edge is real but still tiny. The same relationship holds versus the Intel Core i3-3240T, which also averages 639 and shows a 0.4% delta in the Xeon's favor. In short, the X5472 occupies the same performance envelope as all four rivals, despite coming from a completely different market segment and era.

The 15th percentile ranking reinforces that positioning. Benchmark results indicate the X5472 finishes below the large majority of CPUs in the database. Its server heritage does not translate into modern muscle; the multi-core scores place it alongside entry-level desktop and mobile parts from the rival list.

Power and Thermals

A 120 W TDP is a defining trait of the X5472. For a quad-core 45 nm part, that envelope demands a serious cooling solution, not a slim or passive heatsink. The dual-die construction, with two 107 mm² dies, spreads heat generation across the package, but it also means the cooler must cover two hotspots rather than one concentrated die. Since the chip has no boost clock, it runs at a constant 3.00 GHz under load, producing steady heat output instead of the thermal spikes associated with turbo behavior.

The server/workstation market segment suggests the intended environment was a chassis with strong airflow. The 120 W figure and end-of-life status mean anyone installing this chip today should verify that their Socket 771 board's mounting and case airflow can handle the sustained thermal load. A high-performance air cooler appropriate for that power class is the sensible match; the data gives no indication that a low-profile or fanless design would suffice.

Who Should Consider It

Looking at the Cinebench numbers, the X5472 is not a candidate for modern gaming. The R23 single-core score of 263 and the R20 single-core score of 110 sit far below the level needed for contemporary game engines, which assume dramatically higher per-thread throughput. For legacy titles or non-gaming applications, the four threads can still function, but the 15th percentile position warns against expecting smooth performance in demanding scenarios.

For creation work, the multi-core results are modest: R15 multi-core 188, R20 multi-core 784, and R23 multi-core 1867. Those figures translate into usable performance for office documents, email, web browsing, and light single-threaded applications, but heavy rendering, video encoding, or 3D compositing would quickly expose the chip's age. The data draws a clear line: the X5472 is acceptable for basic productivity and not acceptable for serious creation workloads.

There is a specific audience for which this chip still makes sense. Users maintaining an existing Socket 771 system will appreciate ECC memory support, which matters for storage servers or workstation tasks where data integrity is important. DDR2 or DDR3 flexibility, depending on motherboard, gives builders options with older memory kits. A locked multiplier and no boost clock simplify behavior but remove overclocking as a way to extend its usefulness. Anyone building a new system or expecting competitive performance should look elsewhere; the end-of-life status makes the X5472 a stopgap for legacy hardware rather than a component for new ones.

FAQ

Q: What socket does the Intel Xeon X5472 use?

A: It uses the Intel Socket 771 and is built on the Core 2 architecture with the Harpertown codename.

Q: What memory does it support?

A: The X5472 supports DDR2 or DDR3 depending on motherboard, over a dual-channel memory bus. ECC memory support is present.

Q: Does it have integrated graphics?

A: The fact pack lists no integrated graphics, so a discrete graphics adapter is required for display output.

Q: What are the clock specifications?

A: The base clock is 3.00 GHz. No boost clock is listed, and the multiplier is locked.

Q: How does it rank among all tracked CPUs?

A: It sits at the 15th percentile of all tracked CPUs, with an average benchmark score of 642.

Q: When did it launch and what is its status?

A: It was released on 2007-11-10 and is end-of-life. Launch MSRP was $958.

Platform and Compatibility

The X5472 is a Socket 771 processor designed for the server/workstation segment. Its Core 2 architecture and Harpertown codename tie it to Intel's 45 nm era, with a dual-die package containing two 107 mm² dies. The cache layout is 64 KB of L1 per core and 6 MB of L2 per die, with no L3 cache listed; each die carries its own 6 MB L2 slice.

Memory support is DDR2 or DDR3, depending on motherboard, so the same CPU can be dropped into boards using either memory generation if the platform provides the right slots. The memory bus is dual-channel, with ECC as a supported option. PCIe connectivity is Gen 2, which was appropriate for the systems of its time but dated by current expansion-card standards.

The upgrade path for an existing Socket 771 user is constrained by the platform's end-of-life status. The chip is no longer in production, and the 15th percentile performance leaves little headroom within the same socket. A meaningful improvement would require migrating to a different platform. For anyone staying on Socket 771, compatibility hinges on the motherboard's memory type, its ability to handle a 120 W processor, and its PCIe Gen 2 expansion capabilities. The server/workstation designation also implies boards that expect ECC memory and discrete graphics, consistent with the data showing no integrated graphics.
