Intel Core i5-1035G1 vs Intel Core i7-3770 Comparison

The Intel Core i7-3770 and Intel Core i5-1035G1 are separated by seven years of architecture and a fundamental shift in computing priorities. The data shows a near-total average benchmark tie, with the i7-3770 scoring an average of 9706 against the i5-1035G1’s 9684, a delta of just 0.2%. Yet beneath that surface parity lies a stark split: the older desktop part wins 4 of the 17 head-to-head tests, while the newer mobile chip takes 13. The deciding factor is not raw speed but workload type, with the i7-3770 dominating in data compression, prime number calculation, physics, and random string sorting, while the i5-1035G1 sweeps nearly everything else, particularly encryption and floating-point math.

Where Each One Wins

The i7-3770’s victories are concentrated in memory-latency-sensitive and integer-heavy tasks. Its most decisive win is in Passmark data compression, scoring 105424 against the i5-1035G1’s 80534, a 30.9% advantage. It also leads in Passmark random string sorting by 43.7% (14060 vs 9782) and in Passmark find prime numbers by 52.6% (29 vs 19). These three workloads reward the i7-3770’s larger 8 MB shared L3 cache and higher 3.90 GHz boost clock, which allow it to keep more working data on-die and execute single-threaded iteration loops faster. Its fourth win, Passmark physics (458 vs 423, an 8.3% edge), suggests that its older Ivy Bridge design still handles certain legacy simulation workloads with greater efficiency.

The i5-1035G1, conversely, wins across the board in both single-threaded and multi-threaded synthetic benchmarks. Its largest margin is in Passmark data encryption, where it scores 4094 versus 1866, a 54.4% advantage. This is a massive leap, driven by the Ice Lake architecture’s inclusion of newer cryptographic instruction extensions. It also wins Passmark floating-point math by 24.9% (15483 vs 11628) and Passmark extended instructions by 19% (5524 vs 4476). In Cinebench, the mobile chip leads every iteration: R15 multicore (611 vs 549), R15 singlecore (86 vs 77), R20 multicore (2546 vs 2289), R20 singlecore (359 vs 322), R23 multicore (6062 vs 5450), and R23 singlecore (855 vs 769). Each of these Cinebench deltas sits around 10.1-10.5%, indicating a consistent architectural efficiency advantage rather than a single workload-specific quirk.

Architecture Differences

The two processors embody opposite design philosophies. The i7-3770 is a 22 nm Ivy Bridge desktop part with a 77 W TDP, built for a fixed Intel Socket 1155 platform. It features 4 cores and 8 threads, with a 3.40 GHz base and 3.90 GHz boost clock. Its cache hierarchy includes 64 KB L1 per core, 256 KB L2 per core, and 8 MB shared L3. It supports dual-channel DDR3 memory with 25.6 GB/s bandwidth. The i5-1035G1, in contrast, is a 10 nm Ice Lake-U mobile processor with a 15 W TDP, socketed in Intel BGA 1526. It also has 4 cores and 8 threads, but its base clock is listed at 1000.00 MHz (effectively 1.00 GHz) with a 3.60 GHz boost. Its L1 cache is larger at 80 KB per core, L2 remains 256 KB per core, but L3 drops to 6 MB shared. It supports dual-channel DDR4 with double the memory bandwidth at 51.2 GB/s.

These differences explain the benchmark split. The i7-3770’s higher base clock and larger L3 help in latency-bound workloads like compression and sorting. The i5-1035G1’s newer 10 nm process, larger L1, and doubled memory bandwidth feed its superiority in bandwidth-hungry tasks like encryption and floating-point math. The i7-3770 uses Intel HD 4000 integrated graphics, while the i5-1035G1 uses UHD Graphics. The older part is PCIe Gen 3 with 16 lanes (CPU only), whereas the mobile chip lists PCIe Gen 3 without a lane count. The i7-3770 is end-of-life, released in 2012, while the i5-1035G1 is active, released in 2019.

Head-to-Head Benchmarks

The most striking individual result is Passmark data encryption. The i5-1035G1’s 4094 score more than doubles the i7-3770’s 1866, a 54.4% gap that dwarfs any other delta in the dataset. This is not a marginal win but a generational leap, reflecting the newer chip’s dedicated instructions for AES and similar workloads. Conversely, the i7-3770’s 30.9% win in data compression (105424 vs 80534) is equally emphatic in the opposite direction, showing that its older cache architecture remains superior for dictionary-based compression algorithms. The i7-3770’s 43.7% lead in random string sorting (14060 vs 9782) reinforces this pattern.

In the Cinebench suite, the margin is uniform. Every single-core and multi-core test shows the i5-1035G1 ahead by roughly 10%. For instance, Cinebench R23 multicore scores 6062 for the i5-1035G1 versus 5450 for the i7-3770, a 10.1% difference. Single-core R23 shows 855 versus 769, also 10.1%. This consistency suggests the i5-1035G1’s Sunny Cove cores are simply more efficient per clock, despite the i7-3770’s higher boost frequency. The i5-1035G1 also wins Passmark single-thread by 5.7% (2198 vs 2073) and Passmark multithread by 11.1% (7211 vs 6414). The i7-3770’s only other wins besides compression, sorting, and primes are physics (458 vs 423) and a tie in the duplicate single-thread entries.

The Verdict

From the data, the i5-1035G1 is the stronger all-around processor for modern workloads. It wins 13 of 17 tests, including every Cinebench benchmark and the critical encryption, floating-point, and integer math tests. Its 54.4% lead in data encryption and 24.9% lead in floating-point math make it the clear choice for security-sensitive computations, scientific simulations, or any task that relies on newer instruction sets. The i7-3770, however, remains competitive in specific legacy or memory-latency-bound scenarios. Its wins in data compression (30.9% ahead), random string sorting (43.7% ahead), and find prime numbers (52.6% ahead) indicate that users running older compression software, certain database operations, or prime-number sieving would still find it serviceable.

The choice depends entirely on workload. For general productivity, rendering, or encryption-heavy tasks, the i5-1035G1 is superior despite its lower TDP and mobile pedigree. For users tied to older software that favors large caches and high clock speeds, the i7-3770 offers surprising resilience. The near-identical average scores (9706 vs 9684) obscure this reality; they are not interchangeable parts but complementary tools for different job profiles.

The specification table highlights the core trade-off: the i7-3770 offers a much higher base clock (3.40 GHz vs 1.00 GHz) and more L3 cache (8 MB vs 6 MB), while the i5-1035G1 counters with a smaller process node (10 nm vs 22 nm), larger L1 cache (80 KB vs 64 KB), and over double the memory bandwidth (51.2 GB/s vs 25.6 GB/s). The i7-3770’s 77 W TDP versus the i5-1035G1’s 15 W TDP further underscores the desktop-versus-mobile design split, yet the newer chip still manages to outperform the older one in most benchmarks despite drawing far less power.
