Do I need an aftermarket CPU cooler?

While the stock coolers included with many AMD Ryzen processors are adequate for typical use, an aftermarket cooler is highly recommended for optimal performance, especially if you plan to overclock or push your CPU with demanding tasks. Upgrading to a better cooler can lead to lower temperatures, quieter operation, and higher sustained boost clocks, particularly important for the higher core count CPUs now available.

What chip sockets do AMD processors use?

AMD has transitioned to using primarily Land Grid Array (LGA) sockets for its modern Ryzen and Threadripper processors. This means the pins are located on the motherboard, not the CPU. Key sockets include:

  • AM4 (PGA): While older, AM4 supported a vast range of Ryzen processors, from the first generation up to the Ryzen 5000 series. While still in use, it is a legacy socket.
  • AM5 (LGA): The current standard for Ryzen 7000, 8000, and 9000 series processors, AM5 offers support for DDR5 memory and PCIe 5.0, and future compatibility.
  • sTRX4/TRX40 (LGA): Used for previous generations of AMD Threadripper processors.
  • sWRX8 (LGA): Used for previous generations of Threadripper PRO processors.
  • sTR5 (LGA): The current standard for AMD Threadripper and Threadripper PRO processors, offering enhanced features and performance.

It's crucial to ensure your CPU and motherboard have compatible sockets.

What do cores and threads mean for AMD processors?

  • Cores: The physical processing units within the CPU. More cores generally allow for better multitasking and performance in heavily parallelized workloads.
  • Threads: Virtual processing units that allow each core to handle multiple tasks simultaneously. This technology, known as Simultaneous Multithreading (SMT), enhances performance in applications that can utilize multiple threads.

AMD offers a wide range of processors with varying core and thread counts, catering to diverse needs from everyday computing to professional workloads, with core counts climbing significantly in the latest Threadripper and Threadripper PRO lines.

What do the letters at the end of the processor mean?

AMD's naming conventions provide insights into processor features:

  • X / XT / X3D: High performance variants. The X3D designates processors with AMD's 3D VCache technology, providing a large L3 cache for enhanced gaming performance.
  • No suffix: Standard desktop processor.
  • G: Integrated Radeon graphics.
  • GE: Energy efficient processor with integrated Radeon graphics.

How do AMD CPUs overclock?

AMD Ryzen processors are generally unlocked, allowing for manual overclocking. Additionally:

  • Precision Boost Overdrive (PBO):
  • AMD Ryzen Master: AMD's software utility for monitoring and overclocking Ryzen processors.

What is the difference between Ryzen and Threadripper processors?

  • Ryzen: Designed for mainstream desktops, offering excellent performance for gaming, content creation, and everyday tasks. They utilize the AM5 platform.
  • Threadripper / Threadripper PRO: High end desktop (HEDT) and workstation processors designed for demanding professional workloads like 3D rendering, video editing, and scientific simulations. They feature significantly higher core and thread counts, and use the sTR5 platform.

What is AMD Smart Access Memory?

AMD Smart Access Memory (SAM) allows AMD Ryzen 5000 series (and newer) processors to access the full memory of compatible AMD Radeon RX 6000 series (and newer) graphics cards, resulting in improved gaming performance.

How do AMD CPUs attach to the motherboard?

For AM5, sTR5, and other LGA sockets, the CPU is carefully placed into the socket, aligning the notches on the CPU with the socket. Then the retention arm is pushed down to secure the CPU. It is important to avoid touching the gold contact pads on the bottom of the CPU. For AM4, the CPU is placed aligning the corner with the triangle, and then a retention arm is lowered to secure the CPU.

Choosing a CPU

Your Central Processing Unit - also referred to as your processor or CPU - acts as the mastermind of your computer. The CPU processes thousands of instructions and calculations per second that happen inside a computer, with a speed measured in gigahertz (GHz). Thus, your CPU provides a great deal of the computational power behind everything from creating graphics in PC games to executing functions on Excel spreadsheets.

Other components such as RAM and GPUs help determine a computer's overall power. However, the CPU is ultimately the priority factor in your PCs performance. A CPU with sufficient processing power is important for avoiding the CPU bottleneck phenomenon, which can limit the performance of other hardware, such as your GPU. That is why selecting your CPU is a major decision, and why it is so important to have a wide selection of CPU models to choose from.

Computer processors are available from two major brands: AMD and Intel. Both offer cutting edge processing technologies in their latest and most powerful incarnations, including Intel 14th Gen and AMD Ryzen Zen 4. Coming as early as 2024, AMD will be releasing Zen 5. Both Intel and AMD offer a wide range of entry and mid level CPU options. Both companies use the same architecture, and their product series are named using a similar numbering scheme.

That said, the two brands are not interchangeable. Motherboards only support particular processors, making it very important to be mindful of component compatibility when building a PC. By choosing a processor first, you are setting up the foundation of your PC and eliminating much of the guesswork on your other PC components.

Ultimately, the best CPU for you will depend on your individual needs and budget.

What Do You Need From Your CPU?

The number of cores in a CPU plays a major role in determining its performance. For entry level PCs a quad or six core CPU may be all you need - for power users, we have options between 8 and 64 cores. Note that many processors now also include threading technologies - such as Intel's hyper threading and AMD's simultaneous multi threading - which create multiple logical threads within the same physical CPU core, greatly increasing the CPU's efficiency and parallel processing capability. Multi threaded CPUs are perfect for digital artists, gamers, streamers and anyone else who needs their machine to handle multiple simultaneous apps and processes with no sweat.

As previously noted, you may have the best graphics card on the market, but if you don't pair it with the appropriate CPU, you might not see the full potential of your GPU. However, the best CPU for gaming may not necessarily be the most powerful. When it comes to gaming, CPUs don't need to be the most powerful because the graphics card handles the majority of the workload for video encoding. Instead, gaming CPUs are designed to work with modern graphics cards to create high quality gaming experiences without steep initial costs.

Top of the line mobile and desktop processors can be higher in cost and are typically reserved for such professional tasks as advanced simulations or high resolution renderings. This is why you will often find the most high powered processors used in workstations and applications such as professional 4k video editing. Additionally, if you are planning on doing any streaming or content creation, it may be worth getting a slightly more powerful processor than you initially need, or one with integrated graphics.

Matching Your CPU and Other Computer Hardware

Finding a processor and compatible hardware can be challenging and time consuming when building a computer. CPU Motherboard Combos help alleviate the stress of component purchases and highlight part compatibility while saving money on initial costs.

On top of finding a compatible motherboard for your processor, you will need to find a CPU cooler that fits both components and your PC case. Luckily, some processors come with included coolers that ensure compatibility and provide quality performance for no additional costs. Both AMD's Wraith Stealth Cooler technology and Intel's stock cooling units can offer sufficient performance. However, when buying a separate CPU cooler, be sure to check the socket compatibility to make sure it matches your motherboard's socket and will work with your build.
