What is the difference between AM4 and AM5? AM4 is AMD’s older Ryzen platform built around DDR4 memory, while AM5 is the newer Ryzen platform designed for DDR5, newer CPUs, and a longer upgrade path. 

For gamers building a PC in 2026, this difference matters more than usual because memory prices are still under pressure. If DDR5 pricing makes a new build feel too expensive, AM4 can still be a budget-friendly option, especially for users who want to reuse or buy cheaper DDR4 memory.

AM4 and DDR4: Why It Still Makes Sense for Budget Builds

AM4 is no longer AMD’s newest platform, but it remains attractive for 

. The biggest advantage is DDR4 support, which can help lower total platform cost when memory prices are rising. AM4 motherboards and Ryzen 5000-series CPUs are also widely available, making them easier to fit into a tight budget.

The tradeoff is future upgrade potential: AM4 has fewer modern platform features than AM5, and its CPU upgrade path is more limited. If your goal is affordable 1080p or 1440p gaming today, AM4 can still make sense. If you want a platform to upgrade for years, AM5 is the better long-term choice.

AM5 and DDR5: Better for New Builds, But More Expensive

better platform for a new high-end or long-term gaming PC 

because it supports newer Ryzen CPUs, DDR5 memory, and modern motherboard features such as PCIe 5.0 on supported chipsets. It also gives builders a stronger future upgrade path than AM4. 

The downside is cost. Since AM5 requires DDR5

 users cannot simply buy cheaper DDR4 to reduce the build price. In 2026, with DRAM prices still affected by AI and data center demand, that extra memory cost can make AM5 feel less friendly for budget builders.

AM4 or AM5: What Should PC Builders Choose in 2026?

Choose AM4 if you want to save money, use cheaper DDR4, or build a gaming PC with the best value right now. Choose AM5 if you want better upgrade potential, newer CPU support, and a platform that will last longer. 

The most important thing is to avoid mixing incompatible parts: 

. You cannot install DDR4 memory on an AM5 motherboard, and you cannot install an AM5 CPU on an AM4 motherboard. Before buying, always match the CPU, motherboard, and RAM generation together.

Final Thoughts: Do Not Forget CPU Cooling

Whether you choose AM4 or AM5, the processor still needs proper cooling. The good news is that many modern CPU coolers support both platforms, and darkFlash AIO liquid coolers and air coolers are designed to support AM4 and AM5 builds. 

That means users upgrading from AM4 to AM5, or building a new AMD gaming PC in 2026, do not need to worry about cooler compatibility when choosing the right darkFlash cooling solution. Pick AM4 for lower DDR4-based cost, pick AM5 for long-term upgrades, and make sure your CPU has the cooling it needs to perform reliably.

What is the Difference Between Cores and Threads? 

To understand your computer, imagine your CPU is a Restaurant Kitchen.







Physical Cores = The Chefs





A physical core is like a Chef. If you have 6 cores, you have 6 chefs. They can each handle a completely separate order independently.



Logical Threads = The Hands (Hyper-Threading)





Thanks to technology like Hyper-Threading (Intel) or SMT (AMD), each Chef can use both hands effectively. A thread isn't a new chef; it's just the ability to multitask better. It helps organize background tasks so the Chef never stops working.





Simple Rule: Cores do the heavy lifting (Gaming); Threads handle the background chaos (Discord, Chrome, Windows updates).

Your PC is running louder than usual, and your frame rates are dropping. You’ve cleaned the dust filters, checked your fans, but the temperatures are still creeping up. The culprit might be the most overlooked component in your build: 

Many users install their CPU cooler once and forget about it for years. However, thermal compound is not permanent. It degrades, dries out, and loses its effectiveness over time.

The Golden Rule: How Long Does Thermal Paste Actually Last?

There is no single expiration date for thermal paste, but there is a general consensus among hardware experts and manufacturers.

Cheaper silicon-based compounds tend to dry out ("cure") faster, leading to cracks and air gaps. Premium compounds often use higher-quality suspensions that stay liquid longer.

However, if you are a heavy user who pushes your PC to its limits (video editing, 4K gaming, AI rendering) daily, the heat cycles will degrade the paste faster than a PC used only for web browsing.

5 Signs Your PC Needs New Thermal Paste Immediately

Your PC will tell you when it’s suffering. If you notice any of these symptoms, it’s time to grab a tube of paste:

If your CPU sits at 50°C+ while doing nothing (and it used to be 35°C), the heat transfer is failing.

Are your fans ramping up to 100% speed just by opening a web browser? This suggests the cooler is struggling to pull heat away from the chip.

If your game suddenly lags or stutters after 30 minutes of play, your CPU/GPU might be slowing itself down to prevent damage.

Sudden shutdowns during intensive tasks are a major red flag.

If you remove your cooler for any reason, 

 replace the paste. Never reuse old paste.

 is a standard maintenance task. It's low risk and easy to do.

In many regions, unscrewing your graphics card backplate may void the manufacturer's warranty.

GPUs often require dealing with delicate thermal pads for VRAM and VRMs in addition to the paste for the core.

Unlike CPUs, which have an Integrated Heat Spreader (IHS), GPU dies are exposed. One mistake in mounting pressure can crack the chip.

Repaste your CPU as regular maintenance. Only repaste your GPU if temperatures are critically high and the warranty has expired.

Why Does Thermal Paste Degrade? (The Pump-Out Effect)

Why doesn't it last forever? Two main reasons:

The solvents in the paste evaporate over time, turning the smooth liquid into a chalky, cracked solid that cannot transfer heat efficiently.

As your CPU/GPU heats up, it expands. When it cools down, it contracts. Over thousands of these heating/cooling cycles, the thermal paste is physically "pumped out" from the center of the chip towards the edges, leaving the hottest part of the processor with little coverage.

Over the past year, the memory market has seen an unexpected twist: DDR4, once considered an “outdated” standard, has experienced a dramatic price surge and regained attention from both consumers and industry players. 

While DDR5 was expected to completely dominate by now, DDR4 is proving to be far from obsolete. In this article, we’ll explore the reasons behind DDR4’s surprising comeback and what it means for PC users and the industry.

Leading memory manufacturers like Samsung, Micron, and SK hynix have gradually reduced DDR4 production capacity, shifting resources toward DDR5 and advanced technologies like HBM. As supply tightens, DDR4 modules have become scarcer, driving prices upward.

ChangXin Memory Technologies (CXMT), which once pushed DDR4 prices down by adding extra supply, has also shifted focus to DDR5 in 2025. With fewer manufacturers supporting DDR4, the market balance has swung from oversupply to shortage.

When buyers fear future shortages, they tend to stock up early. PC builders, distributors, and even end-users have been buying DDR4 aggressively, adding further pressure on limited supply.

In a rare twist, DDR4 has in some cases become more expensive than DDR5. Reports have shown DDR4 chips trading at higher prices per gigabyte compared to DDR5, a clear sign of supply-demand imbalance rather than technical merit.

Millions of systems worldwide still rely on DDR4 platforms. For many users, replacing an entire CPU and motherboard just to switch to DDR5 isn’t cost-effective, making DDR4 upgrades the logical choice.

While DDR5 offers higher bandwidth and future scalability, DDR4 remains more than capable for everyday workloads, gaming, and office use. For many, the performance difference isn’t worth the cost of a full platform upgrade.

Upgrading to DDR5 means investing in a new motherboard and often a new CPU. Sticking with DDR4 is a simpler, cheaper upgrade path.

Many DDR4 kits still come with advanced heat spreaders, RGB lighting, and sleek designs, offering strong appeal to gamers and PC builders focused on aesthetics as much as performance.

The DDR4 revival is not simply nostalgia — it’s the result of shrinking supply, platform compatibility, and short-term market behavior. While DDR5 remains the future of memory, DDR4 continues to prove its relevance in 2025.

For PC users, this moment highlights the importance of timing upgrades carefully. DDR4 still offers strong value and compatibility today, but its long-term availability is uncertain. In the fast-moving world of PC hardware, sometimes yesterday’s standard still has a surprising role to play.
