Core i3-1005G1 vs i5-1035G4


Description
Both models i3-1005G1 and i5-1035G4 are based on Ice Lake architecture.

Ice Lake, known as a the 10th generation Intel Core CPUs, it’s a Process-Architecture-Optimization step. It comes with Gen11 Intel’s iGPU, 32kB instruction + 48kB data L1 cache and 512kB L2 cache per core. Ice Lake uses Intel’s 10+ process. This architecture is able to address 128PB of virtual memory and 4PB of physical memory. It comes with DDR4 3200 and LPDDR4X 3733 support.

Using the multithread performance as a reference, the i3-1005G1 gets a score of 116.6 k points while the i5-1035G4 gets 142.7 k points.

Summarizing, the i5-1035G4 is 1.2 times faster than the i3-1005G1. To get a proper comparison between both models, take a look to the data shown below.

Non-optimized benchmark
The benchmark in Mode 0 (FPU) measures cpu performance with non-optimized software. It uses the basic µinstructions from the i386 architecture with the i387 floating point unit. This mode is compatible with all CPUs so it's practical to compare very different CPUs

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.

Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.

If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
