At the dedicated GPU level, these two machines are mirrors of each other — identical Blackwell architecture, the same shading units, memory bandwidth, and a shared 45W TDP. The more revealing differences emerge in CPU-side architecture details. The Lenovo LOQ 15i carries a larger 33 MB L3 cache versus the Acer's 24 MB, and supports faster maximum RAM speeds (5600 MHz vs 5200 MHz). A larger L3 cache reduces how often the CPU must reach out to slower main memory, which benefits latency-sensitive workloads and sustained throughput — consistent with the performance gap already seen in benchmarks.
The Lenovo also gains an edge in instruction set support, including AVX2 — absent on the Acer. AVX2 enables 256-bit wide SIMD operations, which accelerates specific workloads such as scientific computing, certain AI inference tasks, and optimized media processing. For general gaming or productivity use this rarely surfaces, but for technical or compute-heavy users it represents a meaningful architectural capability gap. The overclocked PassMark score reinforces this: 39,466 for the Lenovo versus 30,099 for the Acer — a 31% difference that underscores the CPU headroom the Lenovo carries.
One counter-point favors the Acer: its integrated GPU features 96 execution units compared to the Lenovo's 32, making the Acer's iGPU substantially more capable for light graphics tasks when the dedicated GPU is idle or powered down. Still, in a dedicated gaming laptop context where the discrete GPU handles the heavy lifting, this advantage is situational. Overall, the Lenovo LOQ 15i maintains the edge in this group through superior cache, memory speed ceiling, and raw overclocked CPU throughput.
