AMD Introduces Smaller Zen 4c CPU Cores in Latest Ryzen 7040U Mobile Chips

AMD has released its latest mobile chips, the Ryzen 5 7545U and Ryzen 3 7440U, which are the first laptop processors to feature AMD’s new Zen 4c CPU cores. These cores were previously seen in the EPYC server chips and the entry-level AMD Ryzen Z1 chip for handheld gaming PCs. The Zen 4c cores offer most of the same features as Zen 4 cores but take up less space and run at lower speeds. AMD claims that the Zen 4c cores take up 35% less physical space than Zen 4, allowing for more cores in the same amount of space or the same number of cores in a smaller space.

The Ryzen 5 7545U and Ryzen 3 7440U chips replace the previous Ryzen 5 7540U and Ryzen 3 7440U Phoenix chips. The new chips still have the same number of CPU cores (6 for Ryzen 5 and 4 for Ryzen 3), but now some of those cores are Zen 4c chips, which should bring efficiency improvements and similar performance at lower power levels. The top speeds for the Zen 4c cores are not known, but they are estimated to be about 30% slower than Zen 4 cores.

The updated Ryzen 7040U lineup includes the following chips:

  • Ryzen 7 7840U: 8 x Zen 4 cores, 8 / 16 cores / threads, 3.3 GHz / 5.1 GHz base / boost CPU frequency, 24MB cache, Radeon 780M graphics, DDR5 / LPDDR5 RAM, USB4 support, 15-30W TDP.
  • Ryzen 5 7640U: 6 x Zen 4 cores, 6 / 12 cores / threads, 3.5 GHz / 4.9 GHz base / boost CPU frequency, 22MB cache, Radeon 760M graphics, DDR5 / LPDDR5 RAM, USB4 support, 15-30W TDP.
  • Ryzen 5 7540U: 6 x Zen 4 cores, 6 / 12 cores / threads, 3.2 GHz / 4.9 GHz base / boost CPU frequency, 22MB cache, Radeon 740M graphics, DDR5 / LPDDR5 RAM, USB4 support, 15-30W TDP.
  • Ryzen 5 7545U: 2 x Zen 4 cores, 4 x Zen 4c cores, 6 / 12 cores / threads, 3.2 GHz / 4.9 GHz base / boost CPU frequency, 22MB cache, Radeon 740M graphics, DDR5 / LPDDR5 RAM, USB4 support, 15-30W TDP.
  • Ryzen 3 7440U (old): 4 x Zen 4 cores, 4 / 8 cores / threads, 3 GHz / 4.7 GHz base / boost CPU frequency, 12MB cache, Radeon 740M graphics, DDR5 / LPDDR5 RAM, USB4 support, 15-30W TDP.
  • Ryzen 3 7440U (new): 1 x Zen 4 core, 3 x Zen 4c cores, 4 / 8 cores / threads, 3 GHz / 4.7 GHz base / boost CPU frequency, 12MB cache, Radeon 740M graphics, DDR5 / LPDDR5 RAM, USB4 support, 15-30W TDP.

AMD Unveils Ryzen Threadripper 7000 Series: Up to 96 Cores, DDR5 RDIMMs, and PRO & HEDT CPUs

AMD has announced the release of the Ryzen Threadripper 7000 series, bringing significant updates to their Threadripper processors. The new series offers up to 96 Zen 4 cores, requiring RDIMM memory for Threadripper platforms moving forward. This update caters to both high-end desktop (HEDT) enthusiasts and professionals.

Compared to the previous Threadripper PRO 5000 series processors, the Ryzen Threadripper PRO 7000 WX-Series is a substantial upgrade. While the previous series topped out at 64 cores and 128 threads, the new series allows for up to 96 cores and 192 threads, matching the core counts found in AMD’s EPYC Genoa processors. The Zen 4 Threadripper processors can clock up to 5.3GHz, offer up to 384MB of cache, and include features like AVX-512 and 128 PCIe 5.0 lanes.

The Threadripper PRO 7000 WX-Series parts can reach up to 350 Watts. The AMD Ryzen Threadripper 7000 series processors are in a league of their own at the top-end. Intel currently does not have any Core i9 Extreme Edition processors, and their much-delayed Intel Xeon W-3400 series only goes up to 56 cores. Even if one were to consider the Xeon Scalable “Sapphire Rapids,” there is still a core count limitation. The Threadripper 7000 series processors are expected to provide an interesting battle against the Xeon Scalable processors, especially the Xeon Max.

The AMD Ryzen Threadripper 7000 series is divided into separate platforms for PRO and HEDT. The Threadripper PRO platform, with the WRX90 chipset, offers PRO manageability features, 8-channel memory support, 148 PCIe lanes, and support for Threadripper PRO processors. In the HEDT space, there is the TRX50 chipset, which lacks PRO management features, supports only four-channel memory, has 92 PCIe lanes, and is compatible with both PRO and HEDT Threadripper processors.

The Ryzen Threadripper 7000 series (non-PRO) includes processors with up to 64 cores. The Threadripper 7980X, with a 350 Watt TDP and a maximum turbo boost of 5.1GHz, leads the non-PRO line-up. Other options include the 24-core Threadripper 7960 and the 32-core Threadripper 7970X.

Linux 6.7 Indicates Disabled AMD SVM Virtualization in /proc/cpuinfo

Phoronix reports that Linux will now indicate via /proc/cpuinfo if AMD virtualization (SVM) is disabled. This is a quality of life improvement for home lab virtualization when using AMD CPUs. Previously, checking for the presence of Intel virtualization support and its status could easily be done by looking at the flags in /proc/cpuinfo. However, SVM was always shown in /proc/cpuinfo regardless of whether it was disabled in the BIOS. This oversight is finally being corrected in the upcoming Linux 6.7 kernel cycle, with the possibility of back-porting the fix to existing kernel series.

The patch, developed by Red Hat’s Paolo Bonzini, has been queued into TIP’s x86/cpu branch. This patch will now read the appropriate MSR to verify if SVM has been disabled on AMD and Hygon processors. If SVM is disabled, the CPU capability will be cleared, and it will no longer show in /proc/cpuinfo. Previously, the only indication of AMD SVM being disabled was appearing in the kernel log or KVM virtualization failing to work. This small but useful change makes it much easier to check if virtualization is available via the widely-used /proc/cpuinfo interface.

Improved Performance and Power Efficiency with Linux 6.5 and AMD P-State EPP Default for Ryzen Servers

Linux 6.5 now defaults to the AMD P-State EPP driver for Zen 2 and newer Ryzen systems, as long as the system supports ACPI CPPC. However, the AMD EPYC server processors still continue to use ACPI CPUFreq by default. Given the increasing interest in the AMD Ryzen 7000 series for budget and small-to-medium-sized business (SMB) servers, the performance impact of Linux 6.5 with more server workloads was analyzed.

Phoronix has tested the changes, and testing was conducted comparing the performance of Linux 6.4 against Linux 6.5, both out-of-the-box and using the Ubuntu Mainline Kernel PPA for easy reproducibility. The default change involves going from ACPI CPUFreq Schedutil to AMD P-State EPP with the powersave governor. Additional tests were done with the performance governor for maximum performance. AMD P-State is available on earlier Linux kernel versions but is not set to be used out-of-the-box until Linux 6.5 and later. The testing was done using the ASRock Rack 1U4LW-B650/2L2T, a 1U Ryzen AM5 server platform that supports Ryzen 7000 series processors and ECC memory. No other changes were made to the server during testing, except for swapping out the Linux kernel and running secondary tests with the performance governor. The CPU clock frequency differences in the automated system table were minimal and did not affect the testing results.

The article provides valuable insights for those interested in using Ryzen processors for server applications.
