Intel Core 2 Extreme X7800

The Intel Core 2 Extreme X7800 is a mobile Intel processor from the Core 2 Extreme generation, built on the Core 2 architecture with the Merom XE codename. Released in 2007, it is end-of-life in the database. The chip has 2 cores and 2 threads, a 2.60 GHz base clock, 64 KB of L1 cache per core, and a shared 4 MB L2 cache. Its TDP is 44 W, it uses Intel Socket P, and its launch MSRP was $851. The data places it at the 50th percentile among all CPUs, with an avgBenchmarkScore of 0 and an empty nearestRivals array.

Benchmark Performance

The benchmarks array is empty. The avgBenchmarkScore field is 0, and the percentileVsAllCpus value is 50. Because the nearestRivals array is empty, no exact percentage deltas to named competitors are available in this record. The 50th percentile is the only positional performance datum. This rank places the X7800 at the midpoint of the aggregate CPU distribution. With no benchmark entries, the 0 in avgBenchmarkScore is not a measured workload score; it reflects an empty benchmarks array. That empty array also means no game, office, or creation score has been recorded.

The performance discussion therefore rests on the listed specification: 2 cores, 2 threads, 2.60 GHz base clock, 64 KB per-core L1, and 4 MB shared L2. No boost clock is present, so 2.60 GHz is the only frequency in the data. No memory bandwidth figure is included either, leaving the memory subsystem characterized only by its DDR2 support and dual-channel bus. The 50th percentile rank is a position, not a magnitude of performance. It does not provide a distance from the immediately faster or slower CPUs in the distribution. The absence of a boost clock also means the CPU has no listed higher frequency state.

How It Compares

The nearestRivals field is empty. This means there are no rival names, no rival scores, and no deltaPct values to report. Without that array, a paragraph-by-paragraph comparison against nearest rivals cannot be constructed. The only comparative context in the data is the 50th percentile vs all CPUs. That context is global, not head-to-head. It does not identify which CPUs sit just above or below the X7800.

The X7800 therefore appears in this record as a standalone part with a central aggregate rank. Any specific statement about being ahead of or behind a particular rival would require competitor data that is not present. The absence of nearest rivals is itself a data finding: the database has not paired this CPU with comparable parts for a direct comparison. Without named rivals, the data cannot be used to position the X7800 in a performance ladder. The 50th percentile is the only ladder-like value, and it is an aggregate result rather than a head-to-head result.

Platform and Compatibility

The X7800 uses Intel Socket P. The architecture is Core 2 with the Merom XE codename. It was fabricated by Intel on a 65 nm process, with 291 million transistors and a 143 mm² die. The cache hierarchy has 64 KB of L1 per core, 4 MB of shared L2, and no L3 entry in the data. Memory support is DDR2 and depends on the motherboard. The memory bus is dual-channel, but no memory bandwidth figure is recorded. ECC memory is not supported.

Integrated graphics appears only on certain motherboards as a chipset feature. The PCIe field in the data is null, so no PCIe specification is available. The multiplier is unlocked, and the part number is SLA6ZQZXR. Production status is end-of-life. The upgrade path is therefore tied to existing Socket P boards and their specific DDR2 support. Because memory support is motherboard-dependent, compatibility must be assessed against each board's DDR2 implementation. The memory support field is explicitly tied to the motherboard, which makes the board a central compatibility variable. The unlocked multiplier and Core 2 Extreme generation label both point to a CPU positioned for extreme-tier users, but the record contains no further overclocking data.

Who Should Consider It

The X7800 is a 2-core, 2-thread processor with a 2.60 GHz base clock. Because the benchmarks array is empty and the avgBenchmarkScore is 0, there is no measured score to anchor workload advice. The specification alone suggests workloads that stay within 2 threads. Office tasks with a single active thread fit within that envelope. Applications that can use no more than 2 threads can access both cores.

Games are not covered by any recorded benchmark, so the data cannot support a specific gaming performance claim. Creation workloads that scale beyond 2 threads would meet a hard ceiling at 2 hardware threads. Users considering this CPU should check the thread demand of their software first. Software that can run with a single thread or 2 threads fits the hardware profile. Software designed for more than 2 threads will not be able to use more than the 2 listed threads.

The cache layout provides 64 KB per core and a shared 4 MB L2. The mobile Socket P platform and 44 W TDP also indicate that this part belongs in a mobile system rather than a high-core-count workstation. The unlocked multiplier could appeal to users who want to adjust the CPU ratio on a compatible Socket P board. The end-of-life status means any system build would rely on existing Socket P and DDR2 motherboard support.

Single-Thread vs Multi-Thread Behavior

The thread configuration is 2 cores and 2 threads, so the part lists no additional logical threads. A single-threaded workload uses a core with its private 64 KB L1 and can access the shared 4 MB L2. A 2-thread workload uses both cores and both private L1 caches, while the L2 remains shared. The 64 KB per-core L1 is private to each core, and the 4 MB L2 is the shared pool. In a 2-thread workload, both threads contend for that shared L2. In a single-thread workload, the active thread has its private L1 and the shared L2 without competition from another thread.

The L1 size is expressed per core, and the L2 size is expressed as shared, so the data directly describes a private/shared split. The L3 field is null, meaning no L3 cache appears in the record. The boost clock field is null, so 2.60 GHz is the only frequency information. The data does not include benchmark scores to quantify a performance ratio between single-thread and multi-thread execution. What the configuration does establish is that multi-thread work is capped at 2 threads. For real workloads, this means the CPU can only split work across 2 hardware threads.

Power and Thermals

The TDP in the record is 44 W. This is the only power figure available for the X7800. The 65 nm process node and the mobile market segment are the surrounding thermal facts. No cooler or thermal solution is recorded, so the cooling tier is defined by the 44 W envelope. A compatible Intel Socket P mobile cooling solution would need to handle that TDP.

The record does not include cooler sizes or thermal ratings, so no specific cooling product can be identified. The 65 nm process node is the only manufacturing process listed, and the mobile market segment indicates the intended thermal environment. The 44 W TDP is the value a compatible cooling solution must handle. With end-of-life status, the thermal design is tied to the original platform rather than to an active upgrade ecosystem.
