Meanwhile, a boutique PC builder says Intel didn’t even need to chase high clock speeds
Yet another law firm says it's investigating a potential class action lawsuit against Intel as Raptor Lake CPU owners increasingly complain about chip instability and failure.that it might open up a class action suit on behalf of Intel customers. The firm is opening its inbox to owners of Raptor Lake-based 13th and 14th Gen chips to determine whether enough are impacted to justify litigation.
The key problem is over Raptor Lake's microcode, which was configured to deliver excessive voltage to CPUs. Kaplan Gore points out that"elevated voltages causing the processor to operate outside of safe boundaries can cause irreversible degradation." Voltage-induced damage can cause crashes at clock speeds that were previously stable, or even turn a CPU into a paperweight.on all Raptor Lake CPUs by two years.
That Intel's microcode was delivering too much voltage to Raptor Lake CPUs is likely a consequence of the processor firm chasing the out-of-the-box highest clock speeds the industry has ever seen on a desktop CPU. Raptor Lake's debut flagship, the Core i9-13900K, has a boost clock speed of 5.8 GHz, 100 MHz above AMD's current fastest Ryzen 9 7950X.
However, to push those frequencies, which are only achieved under lightly threaded workloads, it's usually necessary to increase the voltage. This is the reason why overclocking is often seen as dangerous, since hitting higher clock speeds may require a higher voltage. Readers should note that Intel explicitly does not cover overclock-caused damage in its warranty.
