About Intel Core 2 Extreme X7900

The Intel Core 2 Extreme X7900 is a mobile processor built around Intel's Core 2 architecture and the Merom XE codename. The fact pack lists a 65 nm manufacturing process, an Intel foundry, 291 million transistors, and a die size of 143 mm². It has two physical cores, two threads, and a base clock of 2.80 GHz, with no boost clock recorded. The chip is assigned a 44W TDP, uses Intel Socket P, and was released on 2007-08-21. Production status is end-of-life, the database lists no benchmark scores, and the overall percentile versus all CPUs is 50.

Platform and Compatibility

The X7900 fits Intel Socket P motherboards. Memory support is DDR2, but the motherboard determines the exact support details; the memory bus is dual-channel and ECC memory is not supported. The fact pack does not record a PCIe specification, so any expansion details are left to the motherboard and chipset rather than the processor package. Integrated graphics are listed as a chipset feature available on certain motherboards, not as a block inside the CPU die. Because the chip is end-of-life and mobile, the platform's upgrade path is defined by existing Socket P boards and their DDR2 support.

The launch MSRP was $851. The multiplier is unlocked, which allows the multiplier to be changed from its base value. The recorded part number is SLAF4SLA33QVVFQZDX. This is a part that depends heavily on motherboard features for its final capabilities: memory support, integrated graphics, and expansion all appear in the fact pack as motherboard-level or chipset-level details rather than as fixed on-chip specifications.

Power and Thermals

At 44W TDP, the X7900 sits in a modest thermal class for a mobile dual-core processor. The 65 nm process and 291 million transistors on a 143 mm² die provide the transistor budget for two cores at 2.80 GHz within that envelope. A cooling solution designed around roughly 44W of heat output should be enough for a laptop or compact mobile chassis. The lack of a boost clock means the CPU does not have a higher opportunistic frequency state recorded in the fact pack, so thermal planning can focus on the 2.80 GHz base clock and the 44W TDP. For an end-of-life mobile part, this is a relatively contained thermal design that does not appear to demand exotic cooling infrastructure.

Single-Thread vs Multi-Thread Behavior

The core and thread configuration is 2 cores and 2 threads, meaning each core handles one thread and there is no simultaneous multithreading. This makes the X7900 a physical dual-core design with no logical extra threads. The L1 cache is 64 KB, the L2 cache is 4 MB, and no L3 cache is listed. For single-threaded workloads, the operating reference is 2.80 GHz, as there is no boost clock to increase frequency under lighter load. For multi-threaded workloads, the ceiling is exactly two threads running at once.

The data does not include a measured split between single-thread and multi-thread performance, but the specification split is clear. A program that uses one thread will see one core at 2.80 GHz. A program that can use two threads will see both physical cores. A program that wants more than two threads will simply not have extra threads available. This is a predictable execution model, and it caps parallel scaling at two threads.

Who Should Consider It

The 50th percentile placement against all CPUs in the database indicates a mid-pack position. That is not a high-end ranking, and with only two threads the X7900 is not suited to workloads that scale across many cores. Office-style productivity and lightly threaded applications are more plausible use cases because they often need only one or two execution threads. Creation workloads that render, compile, or encode with many threads would hit the two-thread limit quickly.

Gaming use depends on thread utilization. Games that keep to two threads could align with the X7900's structure, while games that spread work across more threads would not be fully served. The unlocked multiplier and 44W TDP make the part potentially interesting to users who prioritize adjusting a mobile Socket P system rather than maximizing core count. The 50th percentile suggests an average position, so this is not a processor for users chasing top-tier multi-thread performance.

Benchmark Performance

The benchmark fields in the fact pack are empty. The benchmarks array contains no entries, and the average benchmark score is 0. This means there is no measured score available to place against rival CPUs. The nearestRivals array is also empty, so no named competitor scores or deltaPct values exist for comparison.

What does a 50th percentile placement actually mean? In this database, it means the X7900 sits exactly at the median of all tracked CPUs. Half of the tracked CPUs are above it and half are below it. Without nearestRivals data, exact percentage deltas cannot be computed. The data can show a middle-of-the-pack global position, but it cannot show whether the X7900 leads or trails any specific rival. The empty nearestRivals list is itself part of the profile: this processor is not currently clustered with any named nearest competitors.

FAQ

Q: What socket does the X7900 use?

A: It uses Intel Socket P.

Q: How many cores and threads does it have?

A: It has 2 cores and 2 threads.

Q: What memory does it support?

A: It supports DDR2, with support depending on the motherboard. The memory bus is dual-channel, and ECC memory is not supported.

Q: Does the processor have integrated graphics?

A: Integrated graphics are listed as a chipset feature on certain motherboards, not as a feature built into the processor itself.

Q: Is the multiplier unlocked?

A: Yes, the multiplier is unlocked.

Q: What is the production status?

A: The production status is end-of-life, and the release date is 2007-08-21.

How It Compares

The nearestRivals list is empty, so there are no rival-specific paragraphs to write. The single positional data point is the 50th percentile across all CPUs in the database, which places the X7900 in the middle of the distribution. No names, scores, or deltaPct percentages are available for comparison. Without nearestRivals entries, exact comparative statements about this processor versus specific competitors cannot be made from the fact pack. The available data shows only the global percentile placement, not a relative standing against any named chip.
