Will they work in my system?\" In a word, yes. In 74 words, yes, because the type of RAM your CPU can use, your system memory, doesn't impact the type of RAM that your graphics card can use. Because the CPU or central processing unit interacts directly with its own memory and the GPU or graphics processing unit interacts directly with its own memory. Those processors work together and communicate with each other through a PCI Express slot. So the type of RAM they're each using doesn't matter. So another common question then is this. Why is video card memory so far ahead of system memory? DDDR5 has been available for years, while DDR4 is still not available, and there's basically no mention of DDR5 at all. Can't we just use GDDR for our CPUs to take advantage of all those technology improvements? Well, this answer is a little bit more complicated. Well, each new generation of GDDR or DDR aims for similar improvements over the last one. higher capacities, reduced heat output and power consumption and higher performance, particularly with respect to maximum bandwidth. That doesn't mean that these technologies are the same. A common misconception is that there is a correlation between the generational numbers in GDDR and DDR, but actually they're independent of each other. GDDR2 was somewhat related to DDR2, but the newer DDDR4 and DDDR5 standards are actually much more closely related to DDR3 than to DDR4 or a future DDR5 standard. Okay, so if they're not really as different as they sound and they're just variations of similar technology, why do we need two different types of memory? Well, as the old saying goes, horses for courses, my friends. I mean, oh gross. I didn't mean meal courses. I meant race courses. Yuck. That's not even a tasteful joke. Sorry. Now that we're back on track, now that's a great joke. My point stands. You want memory that's specialized for your application. The way a typical person uses a computer, we don't actually need any more bandwidth for system memory. It's much more important for everyday tasks to have very low latency access to your RAM with better granularity. While a graphics card is typically moving massive chunks of data into and out of the frame buffer that is the RAM, things like high resolution game textures or large data sets for computer simulation work. The average desktop is being bombarded with a multitude of much smaller transfers like that instant message you just received or that virus scan that's picking through all your files in the background. Normal DDR is optimized for desktop use and GDDR just wouldn't be as suitable in spite of its impressive on paper performance numbers, especially with respect to bandwidth. Speaking of impressive performance, we've got a new sponsor that we absolutely love.
