Intel Core 2 Extreme QX9300

The Intel Core 2 Extreme QX9300 is a mobile processor for Intel Socket P, released on 2008-07-31 and marked End-of-life. It belongs to the Core 2 architecture under the Penryn QC XE codename and the Core 2 Extreme generation. The part has four cores and four threads, a 2.53 GHz base clock, no listed boost clock, and a 45 W TDP. It is built by Intel on a 45 nm process with two 107 mm² dies. The data lists 64 KB of L1 cache, 6 MB of L2 per die, and no L3 cache. Database fields show an empty benchmark array, an average benchmark score of 0, and a percentileVsAllCpus value of 50.

Who Should Consider It

With an empty benchmark array, the database does not provide measured workload scores. The structural data still supports a recommendation profile. The QX9300 has four cores and four threads, so it is a candidate for applications that use at most four concurrently executing threads. Users whose workloads require more than four concurrent threads should look elsewhere, because the thread count is exactly four. The 2.53 GHz base clock, with no boost clock, defines the upper frequency for single-threaded portions of those workloads.

The 45 W TDP and mobile market segment point to a laptop or mobile platform, not a desktop build. Office workloads that are not heavily threaded can run on a four-core mobile part of this class, but no office benchmark record exists. Creation workloads that scale to four threads align with the four-core/four-thread layout and the 6 MB per-die L2 allocation, but no creation score is recorded. Gaming performance cannot be assessed from the data; no gaming benchmark, rival comparison, or percentage delta is present. The unlocked multiplier makes the QX9300 relevant for users on compatible Socket P boards who intend to adjust frequency, while the End-of-life status and empty benchmark array are the main caveats.

Single-Thread vs Multi-Thread Behavior

The absence of a boost clock is the defining single-thread detail. The QX9300 is listed at a 2.53 GHz base clock, and with no boost clock in the data, single-threaded work is tied to that frequency. The processor does not list a higher operating frequency for lightly threaded bursts. It has four cores and four threads, so each core can run one thread; there are no extra software threads beyond the four listed.

Multi-threaded workloads can use all four cores at the same time, but the OS does not have additional logical threads to schedule. Workloads that expect more concurrency would have to share the four available threads. The L2 cache is listed as 6 MB per die, and the package contains two 107 mm² dies, so the cache pool is physically split. There is no L3 cache to act as a shared third-level pool. For cache-sensitive data, the split L2 means locality to a given die is the relevant consideration. The practical result is that workloads with four or fewer threads map cleanly onto this processor, while anything demanding more parallelism hits the four-thread ceiling.

Power and Thermals

Power and thermal behavior is summarized by a 45 W TDP. The chip is built on Intel's 45 nm process and uses two 107 mm² dies, which defines the physical thermal surface. The mobile market segment implies a laptop-oriented thermal solution sized for a 45 W part, rather than a desktop-class cooler. No boost clock is listed, so the data does not include an additional high-frequency power state.

The multiplier is unlocked, allowing a supported Socket P board to adjust frequency from the 2.53 GHz base clock; the resulting power draw after adjustment is not specified. No thermal benchmarks or cooler compatibility details are included. The release date is 2008-07-31, and the production status is End-of-life, so the power envelope belongs to an older mobile Socket P generation. The 45 W figure is the only power-class data present.

FAQ

Q: Does the QX9300 have integrated graphics?

A: The data lists integrated graphics as "On certain motherboards (Chipset feature)," so graphics output is not a guaranteed CPU feature and depends on the motherboard/chipset.

Q: Does it support ECC memory?

A: No. ECC memory support is listed as false.

Q: What is the cache configuration?

A: The data lists 64 KB of L1 cache and 6 MB of L2 per die. There is no L3 cache listed.

Q: Is there a boost clock?

A: No. The base clock is 2.53 GHz and the boost clock field is null.

Q: What memory and PCIe specifications are listed?

A: None are listed. Memory support, memory bus, memory bandwidth, and PCIe fields are all null in the record.

Q: Is the multiplier unlocked?

A: Yes. The multiplierUnlocked field is true.

Benchmark Performance

The benchmark section of the record is empty for the QX9300. There are no benchmark result rows, no nearest rivals, and no percentage differences between rivals. The average benchmark score is 0. With an average score of 0, the percentileVsAllCpus value of 50 cannot be tied to any measured score distribution; it is a positional field with no supporting data.

The only performance-related numbers in the record are the 2.53 GHz base clock, four cores, four threads, 6 MB L2 per die, and 45 W TDP. Because the nearestRivals array is empty, this analysis has no rival score or percentage delta to quote. The database does not support claims of being faster or slower than any named processor. In short, the benchmark performance of the QX9300 is unmeasured in this record.

Platform and Compatibility

The QX9300 uses Intel Socket P and is classified in the mobile market segment. The architecture is Core 2, with the Penryn QC XE codename and the Core 2 Extreme generation label. The process node is 45 nm, and the foundry is Intel. The package consists of two 107 mm² dies.

ECC memory support is absent. Integrated graphics are a chipset feature on certain motherboards, so display capability depends on the platform. The data does not list memory support, memory bus, memory bandwidth, or PCIe connectivity. The part number is SLB5J. The multiplier is unlocked, so a compatible Socket P board can alter the multiplier from the 2.53 GHz base clock. The release date is 2008-07-31, and the production status is End-of-life. The nearestRivals array is empty, so no related processors or upgrade-path alternatives are named.

How It Compares

The nearestRivals array is empty. Therefore, there are no rival names, scores, or exact percentage deltas to compare. The only comparison field with a value is percentileVsAllCpus, set to 50. That value places the QX9300 at the midpoint of the database's all-CPU distribution if taken literally, but with zero benchmark entries it is not attached to a measured average score.

The QX9300's own specifications — four cores, four threads, 2.53 GHz base clock, no boost clock, 45 W TDP, 64 KB L1, 6 MB L2 per die, no L3, and Socket P — constitute the available data for positioning. No competitor can be singled out, and no competitor-specific conclusion is possible from this record.
