How-to Guides                                                   

While many modern games come with built-in benchmarks to help you instantly assess whether your system runs the game smoothly or if settings are too high or too low, not everyone buys a PC just for gaming. For productivity or professional use, third-party benchmarking tools are a better way to measure your system's performance through detailed data.

Developed by Maxon, Cinebench R23 is a free CPU benchmarking tool that evaluates both single-core and multi-core performance using the Cinema 4D rendering engine to simulate real 3D scene rendering. It’s one of the most widely used benchmarking standards in the industry and among DIY enthusiasts. Bonus: It also supports macOS!

Created by CPUID, CPU-Z is a popular tool for viewing detailed hardware information. It also includes a built-in benchmark module that tests both single-core and multi-core performance using compute-heavy tasks. Unlike Cinebench, it doesn’t simulate real-world scenarios but provides quick and simple performance data.

3DMark is a professional-grade benchmarking tool for testing GPU and overall system performance. It can simulate gaming scenarios, heavy graphics rendering, ray tracing, and more—providing a performance score based on your hardware.In addition to GPU tests (like ray tracing and DirectX 12), it can also evaluate CPU performance. 3DMark is an all-in-one solution, but it comes with a price tag.

FurMark is a stress-testing tool specifically for GPUs. It pushes your graphics card to its limits with a highly demanding "furry donut" rendering, helping you test stability, temperature, and cooling efficiency. This type of testing is often referred to as a “burn-in test.” Thanks to its signature rotating donut graphics, FurMark is jokingly nicknamed "the donut test."

"24 Cores," "32 Threads"—CPU marketing is confusing. Do you really need a server-grade processor just to play Call of Duty? Or is a mid-range chip enough? In this guide, we strip away the jargon to explain the difference between Physical Cores and Logical Threads, and reveal the one hidden factor that actually determines your FPS: Cooling.



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).



Single-Core vs. Multi-Core Performance: Gaming vs. Streaming

Should you prioritize frequency (speed) or core count? It depends entirely on how you use your PC.





(AMD RYZEN 7 9800X3D PROCESSOR REVIEW, Vmodtech)



For Pure Gaming: Priority on Single-Core Speed

Most modern games still rely heavily on one "Main Thread." They prefer Fast Cores over Many Cores.





The Sweet Spot: A high-speed 6-core or 8-core CPU is usually the perfect configuration for gaming.



The Reality: A 6-core chip running at 5.0GHz will often beat a 20-core chip running at 3.0GHz in pure FPS.



For Streaming & Content Creation: Priority on Thread Count

If you stream on Twitch via OBS, edit 4K videos, or have 50 Chrome tabs open while gaming, your "Kitchen" is crowded.





Here, extra cores and threads are vital. They handle the video encoding in the background so your game doesn't stutter.



The Hidden Problem: Why High Core Counts Cause Overheating

Here is the fine print that spec sheets don't tell you: High core counts generate massive heat.

Modern CPUs use "Thermal Velocity Boost." They will automatically run faster, but only if they are cool enough. If you buy a high-end i9 or Ryzen 9 but pair it with a weak cooler, the CPU will hit 90°C instantly and Thermal Throttle (slow down). You paid for a Ferrari, but you're driving it in traffic.

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.

Following the recent price rebound of DDR4 and DDR5 memory, signs are emerging that GPU costs may soon climb as well. With flash and GDDR memory prices trending upward, the entire graphics card supply chain could feel the pressure. Here’s a breakdown of what’s happening and what it means for PC builders and gamers.

The semiconductor memory market is entering another upward cycle.

Recent data from TrendForce and DRAMeXchange shows that both DRAM and NAND flash prices have increased by 15–25% in late 2025, after nearly two years of decline.

Major manufacturers like Samsung, Micron, and SK Hynix have reduced older production lines and redirected capacity to meet surging AI and server demand. This has tightened supply for conventional memory chips used across PC components — from RAM modules to graphics cards.

A modern GPU relies on graphics memory (GDDR) to process and store data such as textures, frames, and shader information. In high-performance graphics cards, GDDR6 and GDDR6X memory modules can account for up to 20–25% of total production cost.

This means that even small changes in memory pricing can directly influence the final cost of a GPU — particularly for models with 

The recent surge in memory prices is not limited to DDR modules.

Both GDDR (Graphics Double Data Rate) and flash memory used in GPUs are also affected, due to several combined factors:

Fabrication capacity is increasingly prioritized for high-bandwidth memory (HBM) used in AI accelerators, which reduces supply for traditional GDDR chips used in gaming GPUs.

As manufacturers move from GDDR6 to GDDR7, production of older chips slows down, leading to higher costs for remaining stock.

Flash storage, used in GPU firmware and BIOS components, has seen double-digit percentage increases this quarter.

Longer delivery schedules and component shortages are prompting board makers to stockpile inventory, adding further cost pressure.

These factors collectively increase the bill of materials (BOM) for GPU production, even before assembly and logistics are considered.

While GPU manufacturers typically try to maintain stable pricing, cost pressure from memory components can eventually filter down to consumers.

Rather than direct MSRP hikes, consumers may see fewer discounts, slower price drops, or “refresh” models with adjusted specifications and memory sizes.

Despite upward cost trends, several factors may help contain large-scale price jumps:

As a result, the adjustment in GPU pricing is more likely to be gradual rather than sudden, depending on how memory supply evolves through 2026.

To understand where GPU pricing is heading, pay attention to:

These indicators can reveal whether memory costs are translating into real-world price movement.

Conclusion: The Memory Ripple Effect Continues

The memory market’s rebound is already visible in DDR4, DDR5, and NAND flash segments — and GPUs may be next in line. As GDDR and flash memory costs increase, graphics cards could gradually become more expensive over the coming months.

For PC builders and gamers, it may be wise to plan upgrades early or watch for clearance deals before the next product generation arrives.

While the increase may not be dramatic, the trend shows a clear reminder: in the tech world, memory prices influence everything — even the heart of your gaming PC.

The recent surge in memory prices is not limited to DDR modules.
Both GDDR (Graphics Double Data Rate) and flash memory used in GPUs are also affected, due to several combined factors:

AI-Driven Capacity Reallocation

Fabrication capacity is increasingly prioritized for high-bandwidth memory (HBM) used in AI accelerators, which reduces supply for traditional GDDR chips used in gaming GPUs.



Transition to Newer Nodes

As manufacturers move from GDDR6 to GDDR7, production of older chips slows down, leading to higher costs for remaining stock.



NAND/Flash Price Recovery

Flash storage, used in GPU firmware and BIOS components, has seen double-digit percentage increases this quarter.



Extended Lead Times

Longer delivery schedules and component shortages are prompting board makers to stockpile inventory, adding further cost pressure.



These factors collectively increase the bill of materials (BOM) for GPU production, even before assembly and logistics are considered.



Possible Impact on GPU Prices





While GPU manufacturers typically try to maintain stable pricing, cost pressure from memory components can eventually filter down to consumers.
Based on current trends:





Mid-range GPUs could see 5–10% higher production costs.



High-end GPUs with large VRAM or next-generation memory like GDDR7 could rise by 10–20% in total cost.

Rather than direct MSRP hikes, consumers may see fewer discounts, slower price drops, or “refresh” models with adjusted specifications and memory sizes.



Factors That Could Soften the Effect





Despite upward cost trends, several factors may help contain large-scale price jumps:





Softening GPU demand in the DIY and gaming market may encourage manufacturers to absorb part of the increase.



Improving yields of GDDR7 memory could lower per-chip costs over time.



Remaining inventory from earlier production runs may cushion the short-term impact.

As a result, the adjustment in GPU pricing is more likely to be gradual rather than sudden, depending on how memory supply evolves through 2026.



What to Keep an Eye On

To understand where GPU pricing is heading, pay attention to:





Spot and contract prices for GDDR6/GDDR7 on DRAMeXchange or TrendForce



Quarterly reports from Samsung, Micron, and SK Hynix on memory profitability



MSI, ASUS, and Gigabyte pricing adjustments or inventory clearances



Launch prices of upcoming GDDR7-based GPUs

These indicators can reveal whether memory costs are translating into real-world price movement.







Conclusion: The Memory Ripple Effect Continues

The memory market’s rebound is already visible in DDR4, DDR5, and NAND flash segments — and GPUs may be next in line. As GDDR and flash memory costs increase, graphics cards could gradually become more expensive over the coming months.
