Intel Core i7-960

The Intel Core i7-960 is a 45 nm desktop processor built on the Nehalem architecture under the Bloomfield codename. It provides 4 cores and 8 threads, runs at a 3.20 GHz base clock with a 3.47 GHz boost clock, and carries a 130 TDP. Its average benchmark score is 986, which places it at the 26th percentile of all CPUs in the database. The four nearest rivals all sit within a narrow band around that average, so the i7-960 occupies a tightly contested performance position.

Benchmark Performance

The Cinebench results form the core of the performance picture. In Cinebench R15 multi-core, the i7-960 scores 288. In Cinebench R20, it scores 1203 multi-core and 169 single-core. In Cinebench R23, it scores 2865 multi-core and 404 single-core. The R20 and R23 results both show the same shape: multi-core output is much larger than single-core output, which is consistent with a 4-core, 8-thread design. There is no R15 single-core figure in the data, so the single-thread comparisons rest on R20 and R23.

The aggregate average score of 986 anchors the nearest-rival comparisons. The AMD FX-9830P has an average score of 987 and a delta of -0.1%, meaning the i7-960 is 0.1% slower. The Intel Core i3-4130T averages 989 with a -0.3% delta, so the i7-960 trails by 0.3%. The Intel Core i3-4370T averages 983 with a +0.3% delta, marking the one nearest rival that the i7-960 leads. The Intel Xeon W3565 averages 990 with a -0.4% delta, giving the i7-960 its largest deficit in this group. Across the four rivals, the deltas range from -0.4% to +0.3%, meaning the aggregate performance difference is very small.

The 26th percentile position places the i7-960 in the lower part of the overall database distribution. That global ranking is consistent with a processor from the early Core i7 era, while the nearest-rival comparisons show that it is still competitive with the parts directly around it in aggregate score.

Single-Thread vs Multi-Thread Behavior

The split between single-core and multi-core performance is the defining behavioral trait of the i7-960. Cinebench R20 reports 169 single-core and 1203 multi-core. Cinebench R23 reports 404 single-core and 2865 multi-core. The single-core scores are the ceiling for any workload that depends on one thread, while the multi-core scores represent the throughput available when all 8 threads are active.

The 4 cores and 8 threads matter more for multi-threaded tasks. Rendering, encoding, and batch processing can use the full thread count, and that is where the i7-960 produces its far larger scores. The 3.20 GHz base clock and 3.47 GHz boost clock define the clock operating range, but the observed single-core scores show that the CPU does not transform into a high-single-thread performer at any clock state. The multi-core scores, by contrast, indicate that parallel workloads can extract a much larger share of the processor’s capacity.

The cache hierarchy supports this behavior with 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3. The shared L3 provides a common storage area for all 4 cores and 8 threads, while the per-core L1 and L2 caches keep local data close to each core.

How It Compares

AMD FX-9830P. The FX-9830P posts an average score of 987, which is 0.1% above the i7-960. This is the closest aggregate comparison in the nearest-rival group, and the two processors can be treated as essentially equivalent in the data.

Intel Core i3-4130T. The i3-4130T averages 989, putting it 0.3% ahead of the i7-960. The -0.3% delta means the i7-960 trails this rival in aggregate performance.

Intel Core i3-4370T. The i3-4370T averages 983, and the +0.3% delta means the i7-960 is 0.3% faster. This is the only nearest rival where the i7-960 holds a positive performance edge.

Intel Xeon W3565. The Xeon W3565 averages 990, the highest average score among the four nearest rivals. The -0.4% delta makes this the largest gap in the group, with the i7-960 trailing the Xeon part by 0.4%.

FAQ

Q: What socket does the Intel Core i7-960 use?

A: It uses Intel Socket 1366.

Q: What memory support does it have?

A: It supports DDR3 memory with a triple-channel memory bus. ECC memory is not supported.

Q: Does the Core i7-960 include integrated graphics?

A: No. The integrated graphics entry is null, so a separate graphics solution is required for display output.

Q: Is the multiplier unlocked?

A: No. The multiplier is locked.

Q: What is the production status and release date?

A: The production status is end-of-life, and the release date is 2009-10-19.

Q: How much cache does it have?

A: It has 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3 cache.

Who Should Consider It

For multithreaded creation workloads, the i7-960 is the most capable in the areas where the scores are highest. Cinebench R20 multi-core at 1203 and Cinebench R23 multi-core at 2865 show that all 8 threads can generate substantial aggregate throughput. Rendering, video encoding, and other parallel content-creation tasks can make use of that capacity, especially with a shared 8 MB L3 cache feeding the 4 cores.

For office productivity, the 4 cores and 8 threads provide enough parallelism for multi-tasking, but the single-core scores of 169 in R20 and 404 in R23 are the limiting factor. Light office work will run, but tasks that depend heavily on a single thread will not have a large performance cushion. The 3.20 GHz base clock and 3.47 GHz boost clock are the only clock-related facts in the data, and the benchmark scores place the practical ceiling on single-thread work at those R20 and R23 values.

For gaming, there is no gaming-specific score in the data. The closest proxy is single-thread performance, and the single-core scores indicate a low single-thread ceiling. Games with heavy single-threaded game logic will be constrained by that ceiling, while games that scale across 8 threads can draw on the multi-core scores. The processor’s market segment is Desktop, which means it is positioned for desktop use rather than server or mobile systems.

Platform and Compatibility

The Core i7-960 is built for Intel Socket 1366. It supports DDR3 memory over a triple-channel memory bus, and ECC memory is not supported. The PCIe interface is Gen 2, and there is no integrated graphics, so a discrete GPU is mandatory. The multiplier is locked, which limits clock tuning through the multiplier. The TDP is 130, and the production status is end-of-life, with a release date of 2009-10-19.

The physical package is built on Intel’s 45 nm process, containing 731 million transistors and measuring 263 mm². The matching part number is SLBEU. The cache layout consists of 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3. For upgrade questions, the socket and end-of-life status are the main boundaries: the processor fits Socket 1366, the memory path is DDR3 triple-channel, and the PCIe generation is Gen 2. Any upgrade path is therefore constrained by these platform characteristics.
