CPU Comparison

The Intel Core i7-970 is the outright winner in every benchmark recorded, delivering a consistent performance advantage over the Intel Core i3-8300T. The data shows a clean sweep: the i7-970 wins all six head-to-head Cinebench tests, with a lead ranging from 19.7% to 20% across both single-core and multi-core workloads. For any user prioritizing raw compute throughput, the i7-970 is the clear choice from these two options. However, the i3-8300T is not without merit; it brings a modern platform with DDR4 memory support, a smaller process node, and integrated graphics, making it a more balanced, low-power option for a basic desktop build. The verdict is simple: choose the i7-970 for maximum performance, and the i3-8300T for a more modern, efficient, and feature-complete platform.

Architecture Differences

The two processors represent vastly different eras of Intel design, which explains their divergent characteristics. The Intel Core i7-970 is built on the Westmere architecture with the Gulftown codename, using a 32 nm process node. It is a six-core, twelve-thread processor with a die size of 239 mm² and 1,170 million transistors. Its cache hierarchy includes 64 KB of L1 and 256 KB of L2 per core, plus a shared 12 MB L3 cache. This processor supports DDR3 memory over a triple-channel memory bus and uses PCIe Gen 2. It does not include integrated graphics and does not support ECC memory.

In contrast, the Intel Core i3-8300T is a Coffee Lake part built on a more advanced 14 nm process node. It is a four-core, four-thread processor with a smaller die size of 126 mm². Its cache structure includes the same per-core L1 and L2 sizes (64 KB and 256 KB), but the shared L3 cache is smaller at 8 MB. The i3-8300T supports DDR4 memory over a dual-channel bus with a stated memory bandwidth of 38.4 GB/s, and it includes integrated UHD Graphics 630. It also supports ECC memory and uses PCIe Gen 3 with 16 lanes from the CPU. The i3-8300T has a base clock of 3.20 GHz with no listed boost clock, while the i7-970 has a base clock of 3.20 GHz and a boost clock of 3.47 GHz.

Head-to-Head Benchmarks

The benchmark data is unambiguous: the i7-970 outperforms the i3-8300T in every recorded test. In Cinebench R15 multi-core, the i7-970 scores 562 against 469 for the i3-8300T, a 19.8% advantage. The single-core test in R15 shows a similar pattern, with the i7-970 at 79 and the i3-8300T at 66, a 19.7% lead. This consistency is striking; the performance gap is nearly identical across all tests, suggesting a fundamental advantage in execution capability rather than a workload-specific edge.

Moving to Cinebench R20, the i7-970 scores 2342 in multi-core and 330 in single-core, while the i3-8300T scores 1955 and 275, respectively. The deltas are 19.8% for multi-core and 20% for single-core. The pattern holds in Cinebench R23, where the i7-970 achieves 5577 multi-core and 787 single-core, versus the i3-8300T's 4656 and 657. Again, the i7-970 leads by 19.8% in both tests. The i3-8300T has additional Geekbench scores listed, but no corresponding i7-970 scores are available for direct comparison; the i3-8300T scores 3436 in Geekbench multi-core and 1171 in single-core.

The average benchmark score for the i7-970 is 1613, placing it in the 39th percentile of all CPUs. The i3-8300T has an average score of 1586, also in the 39th percentile. While the raw scores are close, the head-to-head Cinebench results show a clear and repeated 20% performance gap. The i7-970's nearest rivals include the Intel Core i7-10610U at 1611 (0.2% delta) and the Intel Core i3-9100T at 1620 (-0.5% delta). The i3-8300T's nearest rivals include the Intel Core i7-1060G7 at 1591 (-0.3% delta) and the Intel Core i3-8300 at 1564 (1.4% delta).
