Typing feel
The typing feel score is 91.0 for Corsair K70 RGB PRO and 94.0 for Logitech G515 TKL Wired. Logitech G515 TKL Wired leads this dimension. It is a relative index combining how switch force and actuation, keycap profile, stabilizers, and layout affect error rate, fatigue, and long-session rhythm on one baseline. Read the underlying specification rows, source completeness, and exact selling configuration before treating the lead as decisive. Similar averages can hide different weak points, so a small point gap matters less than whether the product removes a concrete problem under your normal usage conditions.
Input latency
The input latency score is 99.0 for Corsair K70 RGB PRO and 98.0 for Logitech G515 TKL Wired. Corsair K70 RGB PRO leads this dimension. It is a relative index combining key-to-screen delay by wired, 2.4 GHz, and Bluetooth mode, polling rate, and reliability during rapid repeated input on one baseline. Read the underlying specification rows, source completeness, and exact selling configuration before treating the lead as decisive. Similar averages can hide different weak points, so a small point gap matters less than whether the product removes a concrete problem under your normal usage conditions.
Build quality
The build quality score is 95.0 for Corsair K70 RGB PRO and 94.0 for Logitech G515 TKL Wired. Corsair K70 RGB PRO leads this dimension.

Who should choose Corsair K70 RGB PRO
Corsair K70 RGB PRO is the stronger fit when its leading dimensions match your primary use. Configuration checks: Verify the exact regional layout and size, switch mechanism, actuation force and hot-swap support, keycap material, wired, 2.4 GHz and Bluetooth modes, polling rate, OS mapping, battery life by lighting mode, and warranty bundle. Then ask whether the product removes a concrete problem with the device you already own. If the gap is small and there is no real pain point, waiting for a price drop or a change in workload can be more rational than upgrading for novelty alone.
Who should choose Logitech G515 TKL Wired
Logitech G515 TKL Wired is the better fit when more of its strengths overlap your priorities and its weaker dimensions remain acceptable. Switching costs: Include adaptation to a new layout and key force, shortcut and macro reconfiguration, keycap, switch, stabilizer, wrist-rest, receiver and cable purchases, charging workflow, and migration of existing profiles. A higher total can still deliver lower practical value when that burden is large, so compare the score lead and switching cost on the same baseline.

Scope and limits of this comparison
This comparison is a structured decision aid built from published specifications and stored representative configurations. Scope and limits: Feel and sound depend heavily on finger force, desk or mat, keycaps, and unit-level switch variance; specifications alone cannot settle wireless interference, firmware behavior, lighting-dependent runtime, or long-term chatter. The scores are relative indicators for setting priorities within one category, not an absolute quality ranking. When a new configuration or verified specification becomes available, the catalog and its comparison pages are regenerated together.
