Intel Core i5-1145G7E vs Intel Core i5-8500T Comparison

Head-to-Head Benchmarks

The recorded data shows a clear sweep in the head-to-head comparisons: the Intel Core i5-1145G7E wins all six shared benchmark tests, with the Intel Core i5-8500T failing to take a single victory. The margins are consistent and meaningful, ranging from 14.0% to 14.5% depending on the test.

In Cinebench R15, the i5-1145G7E scores 757 in multi-core against 662 for the i5-8500T, a 14.4% advantage. The single-core result in the same test is 106 versus 93, a 14.0% lead. Those are substantial gaps for processors from different eras and market segments.

Cinebench R20 follows the same pattern. The i5-1145G7E posts 3156 multi-core and 445 single-core, while the i5-8500T manages 2759 multi-core and 389 single-core. Both deltas sit at 14.4%. The consistency of the margin across different rendering workloads suggests the performance difference is structural rather than workload-specific.

Cinebench R23 confirms the trend with the largest recorded delta. The i5-1145G7E reaches 7516 multi-core and 1061 single-core. The i5-8500T trails at 6571 multi-core and 927 single-core. The multi-core gap is 14.4%, and the single-core gap widens slightly to 14.5%.

The i5-8500T does have one additional recorded benchmark in the database: Geekbench multi-core at 4293 and single-core at 1187. No comparable Geekbench result exists for the i5-1145G7E in the provided data, so those numbers cannot be used for a direct head-to-head comparison.

Looking at overall standing, the i5-1145G7E holds an average benchmark score of 2174 across all tests in the database, placing it in the 47th percentile of all CPUs. The i5-8500T averages 2110 and sits in the 46th percentile. The difference in average score is only 64 points, which is modest, but the head-to-head results tell a more decisive story: in every directly comparable workload, the i5-1145G7E wins by roughly 14%.

Architecture Differences

The two processors come from different Intel generations and are built for different sockets. The i5-1145G7E uses the Tiger Lake architecture, specifically the Tiger Lake-U codename, and mounts on Intel BGA 1449. The i5-8500T uses the older Coffee Lake architecture and mounts on Intel Socket 1151.

Process technology separates them clearly. The i5-1145G7E is fabricated on Intel's 10 nm node with a die size of 144 mm². The i5-8500T is built on the 14 nm node, and the database does not record a die size for it. This node difference helps explain why the newer chip achieves higher performance despite having fewer cores.

Core and thread counts differ substantially. The i5-1145G7E has 4 cores and 8 threads, while the i5-8500T has 6 cores and 6 threads. The i5-8500T has more physical cores but no hyper-threading, whereas the i5-1145G7E leverages simultaneous multithreading to reach 8 threads from 4 cores. This partially explains why the smaller core count still wins multi-core workloads.

Cache layouts are different as well. The i5-1145G7E has 80 KB of L1 per core and 1.25 MB of L2 per core, with 8 MB of shared L3. The i5-8500T has 64 KB of L1 per core and 256 KB of L2 per core, with 9 MB of shared L3. The newer chip has more private cache per core, while the older chip has slightly more shared L3.

Memory support diverges. The i5-1145G7E supports both DDR4 and LPDDR4X in dual-channel configuration. The i5-8500T supports only DDR4, also dual-channel, with a recorded memory bandwidth of 42.7 GB/s. Neither chip supports ECC memory.

PCIe capabilities differ by generation and lane count. The i5-1145G7E provides PCIe Gen 4 with 4 CPU lanes. The i5-8500T provides PCIe Gen 3 with 16 CPU lanes. The newer chip has faster per-lane bandwidth but far fewer lanes, reflecting its mobile design target.

Integrated graphics also differ. The i5-1145G7E carries Iris Xe Graphics G7 with 80 execution units. The i5-8500T carries the older UHD 630. The database does not include graphics benchmark scores for either chip, so the comparison here is limited to architectural presence.

Clock speeds show the i5-1145G7E with a base clock of 1500 MHz and a boost clock of 4100 MHz. The i5-8500T has a base clock of 2100 MHz and a boost clock of 3500 MHz. The newer chip starts lower but boosts significantly higher, which helps explain its single-core advantage.

The i5-1145G7E has a TDP of 28 watts and is classified as a mobile part. The i5-8500T has a TDP of 35 watts and is classified as desktop. The i5-8500T consumes more power, yet still loses in every shared benchmark.

Production status separates them further. The i5-1145G7E is listed as Active, while the i5-8500T is End-of-life. Release dates also differ: the i5-1145G7E launched in September 2020, and the i5-8500T launched in April 2018.

Where Each One Wins

The i5-1145G7E wins every workload category that has matching benchmark data. In multi-core rendering, it leads by 14.4% across Cinebench R15, R20, and R23. In single-core rendering, it leads by 14.0% to 14.5% across the same tests. No test in the head-to-head set favors the i5-8500T.

For users prioritizing single-threaded responsiveness, the i5-1145G7E is the clear choice. Its boost clock of 4.10 GHz against the i5-8500T's 3.50 GHz, combined with the newer architecture and larger per-core cache, produces a consistent 14% single-core edge. Applications that are latency-sensitive or lightly threaded will favor this chip.

For multi-threaded workloads, the i5-1145G7E still wins despite having fewer physical cores. The combination of hyper-threading, higher boost clock, and newer process node overcomes the i5-8500T's two extra physical cores. The 14.4% multi-core delta across all three Cinebench versions indicates this is not a fluke of a single test.

The i5-8500T does have advantages in platform flexibility. It uses the Socket 1151 platform with 16 PCIe Gen 3 lanes, which is far more expandable than the i5-1145G7E's 4 PCIe Gen 4 lanes. For a desktop build with multiple add-in cards or NVMe drives, the i5-8500T platform offers more connectivity options.

The i5-8500T also has more shared L3 cache at 9 MB versus 8 MB, though the per-core cache on the i5-1145G7E is substantially larger. The practical impact of the L3 difference is likely small given the benchmark results.

The i5-8500T's Geekbench results, which have no direct counterpart for the i5-1145G7E in the data, show 4293 multi-core and 1187 single-core. These numbers place it in a specific performance tier, but without a matching i5-1145G7E result, they cannot be used to establish a relative ranking.

The Verdict

The benchmark data is unambiguous. The Intel Core i5-1145G7E outperforms the Intel Core i5-8500T in every directly comparable test, with margins between 14.0% and 14.5%. This holds for both single-core and multi-core workloads across three different Cinebench versions.

The i5-1145G7E achieves this with a lower TDP of 28 watts versus 35 watts, fewer physical cores, and a smaller process node. It is the newer design, launched in September 2020 versus April 2018, and remains in active production while the i5-8500T is end-of-life.

Buyers should choose the i5-1145G7E if they want the stronger performer in rendering workloads, single-threaded tasks, or any application that matches the Cinebench benchmark pattern. It also offers the advantage of newer PCIe Gen 4 support and a more modern integrated GPU, though with only 4 CPU lanes.

The i5-8500T retains appeal only for those building on the Socket 1151 desktop platform who need 16 PCIe Gen 3 lanes for expansion. It has more physical cores and slightly more L3 cache, but the recorded benchmarks show those advantages do not translate into faster results. Its Geekbench scores are recorded in the database, but no matching i5-1145G7E result exists for comparison.

For a system where raw CPU performance matters, the i5-1145G7E is the data-supported choice. The i5-8500T is a capable older desktop part, but it loses every head-to-head test and carries a higher power draw while doing so.
