Intel Core i3-1115GRE vs Intel Core i5-3570T Comparison

Head-to-Head Benchmarks

The data is unambiguous: the Intel Core i3-1115GRE wins every recorded head-to-head benchmark against the Intel Core i5-3570T. The newer Tiger Lake mobile chip leads across all five Cinebench tests, with deltas consistently around 15.5 to 15.6 percent. In Cinebench R23 multicore, the i3-1115GRE scores 3899 against 3293 for the i5-3570T, a 15.5 percent advantage. Single-core performance follows the same pattern: the i3-1115GRE posts 550 in Cinebench R23 single-core versus 465 for the i5-3570T, again a 15.5 percent gap.

The multicore results are especially telling because the i5-3570T has four physical cores while the i3-1115GRE has only two. Despite having half the physical core count, the i3-1115GRE still outpaces the older quad-core in every multicore workload. In Cinebench R15 multicore, the i3-1115GRE scores 392 versus 331, a 15.6 percent lead. Cinebench R20 multicore shows 1637 against 1383, a 15.5 percent margin. The consistent delta across all tests suggests the architectural efficiency of Tiger Lake more than compensates for the core count deficit.

The i5-3570T does not win a single benchmark in this comparison. Its average benchmark score sits at 1136, while the i3-1115GRE averages 1127, a negligible 0.8 percent difference in overall database standings. Both processors land in the 32nd percentile of all CPUs tracked in the database, meaning they occupy a similar tier of general performance despite the i3-1115GRE winning every direct head-to-head test.

The i3-1115GRE records a Cinebench R15 single-core score of 55, a figure that appears in the database but is not part of the head-to-head comparison. This anomalous result likely reflects a testing condition rather than actual performance, since its R20 single-core score of 231 and R23 single-core score of 550 align with the expected pattern. The i5-3570T has no R15 single-core entry in the database. When comparing Geekbench scores, the i5-3570T shows 1705 multicore and 578 single-core, but no Geekbench results are recorded for the i3-1115GRE, so those cannot be directly compared.

Architecture Differences

The two processors come from entirely different eras of Intel design. The i5-3570T uses the Ivy Bridge architecture on a 22 nm process node, while the i3-1115GRE uses the Tiger Lake architecture (Willow Cove-U) on a 10 nm node. This process shrink explains much of the performance-per-watt difference between them.

Core configuration differs sharply. The i5-3570T has 4 cores and 4 threads, with no hyper-threading. The i3-1115GRE has 2 cores and 4 threads, using hyper-threading to reach the same thread count. The i3-1115GRE compensates for fewer physical cores with a significantly higher boost clock: 3.90 GHz versus 3.30 GHz for the i5-3570T. Base clocks are close, at 2.20 GHz for the i3-1115GRE and 2.30 GHz for the i5-3570T.

Cache layouts have changed substantially between generations. The i5-3570T has 64 KB of L1 cache per core, 256 KB of L2 per core, and 6 MB of shared L3 cache. The i3-1115GRE has 80 KB of L1 per core, 1.25 MB of L2 per core, and the same 6 MB of shared L3. The larger per-core L1 and L2 caches on the Tiger Lake part help feed its higher IPC design. Die size is 160 mm² for the i5-3570T with 1,400 million transistors, while the i3-1115GRE uses a 144 mm² die; transistor count is not recorded for the Tiger Lake chip.

Memory support diverges completely. The i5-3570T supports DDR3 memory only, while the i3-1115GRE supports DDR4 and LPDDR4X. Both use dual-channel memory buses. The i3-1115GRE also supports ECC memory, a feature absent from the older chip. PCIe connectivity differs as well: the i5-3570T offers Gen 3 with 16 lanes (CPU only), while the i3-1115GRE offers Gen 4 with 4 lanes (CPU only). The newer standard provides more bandwidth per lane, though the lane count is lower.

Integrated graphics are from different families. The i5-3570T pairs with Intel HD 2500, while the i3-1115GRE includes UHD Graphics G4 48EU. The database does not record graphics benchmark scores for either chip, so direct GPU comparison is not possible.

Market positioning also differs. The i5-3570T is a desktop processor on Intel Socket 1155, released on 2012-04-28. The i3-1115GRE is a mobile processor on Intel BGA 1449, released on 2020-09-01. The i5-3570T has no recorded production status, while the i3-1115GRE is listed as Active. The power envelope is dramatically different: the i5-3570T has a 45 W TDP, while the i3-1115GRE draws only 15 W. This threefold difference in thermal design power is central to understanding where each chip belongs.

The Verdict

The benchmark data points decisively to the Intel Core i3-1115GRE as the stronger performer. In every recorded Cinebench test, it beats the i5-3570T by roughly 15.5 percent regardless of whether the workload is single-threaded or multi-threaded. This consistency matters: it shows the Tiger Lake architecture delivers a uniform performance uplift across different rendering scenarios, not just in one narrow test.

The i5-3570T's only statistical advantage is its average benchmark score of 1136 versus 1127 for the i3-1115GRE, a 0.8 percent difference that falls within rounding of rival comparisons. The i5-3570T's nearest rivals include the Intel Core i5-2550K at an identical 1136 average score, the Intel Xeon E5640 at 1137, and the AMD Athlon Silver PRO 3125GE at 1138. The i3-1115GRE's nearest rivals include the Intel Core i5-3330S and Intel Core i7-2720QM, both at 1128. These nearby scores confirm that both chips occupy a similar overall performance tier in the database, despite the i3-1115GRE winning all direct comparisons.

Power efficiency is where the two chips diverge most dramatically. The i3-1115GRE delivers superior performance at 15 W, one-third of the i5-3570T's 45 W TDP. For any system where thermal headroom or battery life matters, the choice is clear. The i3-1115GRE also brings modern platform features: DDR4/LPDDR4X memory, ECC support, PCIe Gen 4, and an active production status with a recorded launch MSRP of $338.

The i5-3570T remains relevant only in legacy desktop contexts. Its 16 PCIe Gen 3 lanes exceed the 4 lanes of the i3-1115GRE, which could matter for systems needing more expansion capacity from the CPU. Its desktop socket and DDR3 support suit older motherboards. But the data shows no performance scenario where the older chip wins.

Where Each One Wins

The Intel Core i3-1115GRE wins in every measured performance category. For single-threaded workloads, its Cinebench R23 single-core score of 550 versus 465 gives it a 15.5 percent edge. For multicore rendering, its Cinebench R23 multicore score of 3899 versus 3293 delivers the same margin. This makes it the better choice for rendering tasks, general productivity, and any workload that benefits from higher IPC and boost clocks.

The i3-1115GRE is also the clear winner for mobile and low-power systems. Its 15 W TDP, active production status, and support for DDR4/LPDDR4X memory make it suitable for modern laptops and embedded applications. The ECC memory support adds reliability for industrial or edge deployments.

The Intel Core i5-3570T has no benchmark wins in this comparison, but its specification sheet suggests specific use cases where it could still fit. Its 16 PCIe Gen 3 lanes provide more expansion capability than the 4 lanes of the i3-1115GRE, assuming the workload benefits from CPU-attached devices. The desktop Socket 1155 and DDR3 memory support align with older platforms already in the field.

Power-sensitive users should note that the i5-3570T's 45 W TDP is three times higher than the i3-1115GRE 15 W TDP, making the older chip less suited to thermally constrained environments. The mobile market segment classification, desktop for the i5-3570T and mobile for the i3-1115GRE, further separates their intended environments. For any new designs, the active i3-1115GRE with its 2020 release date and 10 nm Tiger Lake architecture clearly supersedes the 2012-era i5-3570T in the database rankings.
