New AMD P-State Patch Delivers Major Linux Gaming Performance Boost

3 weeks ago
by George Whittaker

A newly proposed patch for the Linux kernel's AMD P-State CPU frequency scaling driver is showing impressive gaming performance improvements, potentially delivering a noticeable boost for Ryzen users without requiring new hardware. Early benchmarks indicate that the optimization can significantly improve frame rates in CPU-bound games by allowing processors to respond more quickly to changing workloads. (phoronix.com)

Although the patch has not yet been merged into the mainline Linux kernel, the initial results have generated considerable excitement among Linux gamers and kernel developers alike.

What Is AMD P-State?

AMD P-State is the modern CPU frequency scaling driver for AMD Ryzen processors on Linux. Rather than relying on the older ACPI CPUFreq driver, AMD P-State communicates directly with the processor to adjust clock speeds based on workload demands.

Its goals include:

  • Faster frequency scaling
  • Improved power efficiency
  • Better responsiveness
  • Higher performance during demanding workloads
  • Lower power consumption when the system is idle

Most modern Linux distributions already support AMD P-State on compatible Ryzen processors. (kernel.org)

A Focus on Gaming Performance

The new patch specifically targets how quickly AMD P-State responds when a game suddenly demands additional CPU performance.

Many games rapidly alternate between light and heavy CPU workloads. If the processor takes too long to increase its clock speed, short performance dips can occur.

The proposed optimization reduces that delay, allowing the CPU to boost more aggressively when needed and helping maintain smoother gameplay. (phoronix.com)

Promising Benchmark Results

According to early testing, the patch delivers meaningful improvements across several Linux gaming workloads.

Reported benefits include:

  • Higher average frame rates
  • Better 1% low FPS performance
  • Faster CPU frequency response
  • Improved responsiveness during gameplay
  • More consistent frame delivery

The biggest gains appear in CPU-limited games where processor performance has a greater impact than GPU performance. Systems that are already GPU-bound may see smaller improvements. (phoronix.com)

Designed for Modern Ryzen CPUs

The patch targets systems using the AMD P-State driver, which supports many recent Ryzen processors.

Compatible platforms generally include:

Meta AI Hacked External Systems During Cybersecurity Testing

3 weeks ago
wiredmikey shares a report from SecurityWeek: Meta is the latest major AI developer to admit that its models broke loose during cybersecurity testing and hacked external systems. The tech giant said in a statement to the media on Wednesday that the incident occurred during independent evaluations conducted by Israeli AI security startup Irregular. The tested AI models were inadvertently allowed to access the internet due to a misconfiguration, which led them to exploit a vulnerability in an unnamed third-party service. It's unclear if it was a known flaw or a zero-day. The Information [gated] learned that the Meta AI attacks involved the company's advanced Muse Spark 1.1 model, which breached an unnamed organization's systems and made unauthorized changes to its internal environment. Meta said it learned of the AI models going rogue after being notified by Irregular. The company is conducting an investigation and it has promised to issue a "full retrospective" once it has all the facts. A spokesperson for Irregular said the incident was the "exact same evaluation-environment issue that was already disclosed by Anthropic last week" and that it did "not involve a "sandbox escape or a sophisticated cyber action." It contrasts with OpenAI, whose AI agent independently exploited a novel vulnerability to reach the internet during cyber testing. Not only did it breach Hugging Face but it also hacked multiple third-party accounts and services as part of the attack.
