Intel Core i3-1115G4E vs Intel Core i3-8300T Comparison

The Intel Core i3-8300T and Intel Core i3-1115G4E land in the same performance percentile, but they achieve it through very different means. The 8300T, a 35W desktop chip, uses four physical cores to grind through multi-threaded workloads, while the 1115G4E, a 15W mobile part, relies on a higher boost clock and a newer architecture to win single-threaded tests. The benchmark data shows a clear split: the 8300T wins 7 of 8 head-to-head tests, but the one loss is a decisive one.

Head-to-Head Benchmarks

The most striking result is in Geekbench single-core, where the 1115G4E scores 1702 against the 8300T’s 1171. That is a 31.2% advantage for the mobile chip, and it is the largest delta in any test. This is not a marginal win; it is a generational leap in per-thread performance. The 8300T’s older Coffee Lake architecture simply cannot match the IPC of Tiger Lake at the same clock speed.

Every other benchmark, however, favors the 8300T. In Cinebench R15 multi-core, the 8300T scores 469 versus 452, a 3.8% edge. The single-core result in the same test is closer in percentage terms — 66 versus 63, a 4.8% win for the 8300T — but the absolute scores are low for both parts. Moving to Cinebench R20, the 8300T wins multi-core 1955 to 1887 (3.6%) and single-core 275 to 266 (3.4%). The pattern continues in Cinebench R23: multi-core 4656 to 4493 (3.6%) and single-core 657 to 634 (3.6%).

The biggest multi-core gap appears in Geekbench multi-core, where the 8300T scores 3436 against 2972 for the 1115G4E. That is a 15.6% difference, far larger than the Cinebench multi-core deltas. This suggests the 8300T’s four physical cores provide a significant advantage in workloads that scale well across cores, even though the 1115G4E also has four threads via hyper-threading. The 8300T’s wins are consistent and narrow in Cinebench, but the Geekbench multi-core result shows that when the workload is properly parallelized, the desktop part pulls ahead substantially.

Architecture Differences

The two processors come from different eras and are built for different sockets. The 8300T uses Coffee Lake on a 14 nm process, with a die size of 126 mm². It is a desktop part on Intel Socket 1151. The 1115G4E uses Tiger Lake-U on a 10 nm process, with a die size of 144 mm², and is a mobile part on Intel BGA 1449. The node difference matters: 10 nm allows for denser, more efficient transistors, which helps explain the 1115G4E’s single-core superiority despite its lower base clock.

Core counts differ significantly. The 8300T has 4 cores and 4 threads, while the 1115G4E has 2 cores and 4 threads. This means the 8300T has two additional physical cores, which is the primary reason for its multi-core wins. The cache layout also reflects the architectural changes. The 8300T has 64 KB of L1 per core and 256 KB of L2 per core, with 8 MB of shared L3. The 1115G4E has 80 KB of L1 per core, a much larger 1.25 MB of L2 per core, and 6 MB of shared L3. The larger per-core caches on the 1115G4E likely contribute to its better single-threaded performance.

Memory support differs as well. The 8300T supports DDR4 and has a memory bandwidth of 38.4 GB/s, while the 1115G4E supports both DDR4 and LPDDR4X. The 1115G4E does not have a listed memory bandwidth figure in the data. ECC memory is supported on the 8300T but not on the 1115G4E. PCIe capabilities also diverge: the 8300T offers Gen 3 with 16 lanes (CPU only), while the 1115G4E offers Gen 4 with only 4 lanes (CPU only). The 8300T’s higher lane count suits a desktop platform with discrete GPUs, while the 1115G4E’s Gen 4 support is newer but limited in lane count for mobile designs.

Integrated graphics differ: the 8300T has UHD Graphics 630, while the 1115G4E has UHD Graphics G4 48EU. The 1115G4E’s graphics are part of a Tiger Lake package with a newer architecture, but the data does not include graphics benchmarks. Production status also separates them: the 8300T is end-of-life, while the 1115G4E is active. The 8300T launched in April 2018 with a launch MSRP of $138; the 1115G4E launched in September 2020 with a launch MSRP of $285.

FAQ

A: The Intel Core i3-1115G4E wins single-core tests decisively. In Geekbench single-core, it scores 1702 versus 1171 for the 8300T, a 31.2% advantage. It also wins Cinebench R23 single-core 634 to 657? No — the 8300T wins that test 657 to 634, a 3.6% edge. The Geekbench single-core result is the outlier, and it is the only single-core test the 1115G4E wins.

Q: Does the 8300T win all multi-core tests?

A: Yes. The 8300T wins every multi-core benchmark in the head-to-head set. Its margins range from 3.6% in Cinebench R20 and R23 to 3.8% in Cinebench R15 and 15.6% in Geekbench multi-core. The 15.6% Geekbench margin is the largest multi-core delta.

Q: How do their average benchmark scores compare?

A: The average benchmark scores are close. The 8300T averages 1586, while the 1115G4E averages 1559. Both sit at the 39th percentile of all CPUs, meaning they are statistically similar overall, despite the different win patterns.

Where Each One Wins

The 8300T wins in multi-threaded applications. Its four physical cores give it a structural advantage that shows up in every multi-core benchmark. The 15.6% Geekbench multi-core margin is the clearest signal: heavily parallel workloads like video encoding, compilation, or rendering will favor the 8300T. Its narrow Cinebench multi-core wins (3.6-3.8%) confirm that even in mixed workloads, the extra cores help. The 8300T also supports ECC memory and has 16 PCIe Gen 3 lanes, making it suitable for a desktop workstation where stability and expansion matter.

The 1115G4E wins in single-threaded responsiveness. Its Geekbench single-core score of 1702 is 31.2% higher than the 8300T’s, which indicates better performance in lightly-threaded tasks like web browsing, office applications, or legacy software that runs on one or two threads. The 1115G4E also has a much lower TDP (15W versus 35W), which makes it viable for fanless or passively cooled mobile designs. Its support for LPDDR4X memory and PCIe Gen 4, albeit with only 4 lanes, makes it a more modern platform for compact embedded systems.

The 8300T is the better choice for a fixed-location system where power draw is less critical and multi-core throughput is the priority. The 1115G4E is the better choice for a mobile or embedded application where the 15W TDP and single-core speed are paramount. Neither part excels at both, and the benchmark data shows that choosing between them is a trade-off between core count and architectural efficiency.

The Verdict

The data points to a clear split: pick the Intel Core i3-8300T if your workloads are multi-threaded and you can accommodate a 35W desktop processor. It wins 7 of 8 head-to-head benchmarks, including every multi-core test, and its 15.6% Geekbench multi-core advantage shows real strength in parallel tasks. Its 16 PCIe Gen 3 lanes and ECC support make it a sensible choice for a budget workstation or server-like desktop use.

Pick the Intel Core i3-1115G4E if single-threaded performance and low power consumption are the priorities. Its 31.2% Geekbench single-core win is the most dramatic result in the comparison, and its 15W TDP makes it suitable for mobile or embedded designs where cooling is limited. The 1115G4E is the more modern architecture, but its two physical cores cap its multi-core potential.

Both processors sit at the 39th percentile of all CPUs, and their average benchmark scores are within 1.7% of each other (1586 versus 1559). The 8300T is a mature, end-of-life desktop part with a $138 launch MSRP; the 1115G4E is an active mobile part with a $285 launch MSRP. For a desktop builder focused on multi-core, the 8300T is the data-backed winner. For a mobile or embedded designer who needs fast single-threaded response in a 15W envelope, the 1115G4E is the only logical pick.
