Differences in the GDDR type of graphics card memory

You can think of the memory type as a road, and the DDR2 memory type is a two-way road, and if you squeeze it, you can drive up to three cars side by side, which is very crowded. DDR3 is a three-lane road, and the road is wider, and DDR5 is a wide road, and the traffic flow is large.

In this way, you can see the difference between DDR2 and DDR5, DDR5 has a wide road, more cars can walk, and the processing speed is faster than DDR2 type graphics cards.

The most obvious is the difference in frequency.

The frequency of GDDR2 is generally 800MHz, GDDR3 is generally between 1200-1800MHz, of course, there are 2000MHz or higher, and GDDR5 can reach 3200-4000MHz, so it should be seen, right? With each generation of video memory, their frequency increases exponentially. Also, the graphics card is not just based on the quality of the video memory to determine the performance.

Well, 100kill is right but not kind (if you give 200 points, her answer is the real standard + major), and 20021257 classmate finally gave full play to the strength of the talent and wrote these common senses. Add to lz:

The core frequency is the GPU frequency.

Memory issues. NVIDIA's high-end graphics cards have always been overpowering ATI, and even more so after the name change to AMD. In terms of mainstream high-end, in order to compete with NVIDIA in terms of video memory speed, AMD uses 4GHz (equivalent frequency) GDDR5, while NVIDIA only uses GDDR3, why do you still say "compete"?

Take GTX280 and HD4890 as examples, because the N card has a huge bit width of 512 bits, while the A card only has 256 bits, the actual video memory speed, the N card has to win by 25%! So although A looks scary with GD4 and GD5 all day long, the speed has never outperformed GD3 with N cards

1. The GDDR5 of the graphics card means that this is the fifth generation of video memory type, compared with GDDR3 and GDDR4, the third and fourth generations of technology are more advanced, the frequency is higher, and the picture speed will be faster when performing audio and video entertainment, the screen resolution will be higher, and the operation will be smoother.

2. The full name of GDDR5 is Graphics Double Data Rate Ver 5 Synchronous Graphics Random Access Memory.

3. GDDR5 and GDDR4 are based on DDR3 SDRAM, the basic memory architecture is similar to DDR3, and the memory prefetch is also the same 8N setting. The so-called "prefetching" is the ratio of the transfer rate of the memory array inside the memory chip to the access transfer rate of the output input (iO), and "8N" represents the IO buffer to read the data of 8 bits in the memory array at one time, increasing the transfer speed outside the memory.

What is GDDR6 equivalent to the graphics card, which is simply put, that is, the cache of the graphics card. GDDR6 GDDR6 is the full name of Graphics Double Data Rate, Version 6, which belongs to the sixth generation version of the graphics with double data transfer rate memory. In simple terms, it is the cache of the graphics card.

GDDR6 is the latest sixth-generation technology, which is more advanced and more frequent than the current mainstream GDDR5, which is more conducive to improving the performance of graphics cards. 1. GDDR6 memory adopts dual-channel read/write design; 2. GDDR6 memory speed up to 16Gbps; 3. GDDR6 not only has stronger performance, but also lower power consumption; 4. GDDR6 video memory standard, the highest cache capacity in the future can be as high as 32GB; 5. Wheel leakage. GDDR6 memory bandwidth can reach 16Gbps 384bit 8=768Gb s, taking GTX1080 as an example, its memory bandwidth is 11*256 8=352GB, which is almost doubled.

GDDR5 refers to the type of memory of the graphics card.

GDDR5 (Graphics Double Data Rate, Version 5) SDRAM is a high-performance graphics memory designed for bandwidth-hungry computer applications. It's the mainstream now. GDDR5 needs to be matched with PCI-E or above specifications of graphics cards to support, GDDR5 video memory uses DQ parallel dual bus, which is equivalent to providing an additional channel on the basis of GDDR3, while GDDR3 video memory has only one channel, so GDDR5 theoretical speed can reach more than 4 times that of GDDR3, and high frequency above 5000MHz becomes possible, through high frequency it is possible to make a 128bit graphics card performance exceed DDR3's 256bit graphics card.

GDDR6 graphics cards are mid-range. GDDR6 stands for Graphics Double Data Rate, Version 6 and is a sixth-generation graphics memory with double data rate.

To put it simply, that is, the cache of the graphics card, GDDR6 is the latest sixth-generation technology, which is more advanced and more frequent than the current mainstream GDDR5, which is more conducive to improving the performance of the graphics card.

Generally speaking, video memory is also a factor that affects the performance of graphics cards, and GDDR6, as the next generation of GDDR5, is mainly upgraded in the following aspects.

1. GDDR5X 5 4 3 2 1 video memory and other versions, the state pair is a single-channel read/write design, while GDDR6 video memory adopts a dual-channel read/write design.

2. GDDR6 memory speed is up to 16Gbps, while GDDR5 is only 12Gbps.

3. The working voltage of GDDR6 is lower than that of the previous generation GDDR5 video memory, which means that GDDR6 not only has stronger performance, but also lower power consumption.

4. The maximum cache capacity of GDDR6 video memory standard in the future can be as high as 32GB, while the most common GDDR5 in the previous generation is 8GB single granularity.

5. GDDR6 memory bandwidth can reach 16Gbps 384bit 8=768GB S, taking GTX1080 as an example, its memory bandwidth is 11*256 8=352GB, and the bandwidth has almost doubled.

GDDR6 is currently the most powerful kind of video memory, and many mainstream mid-range graphics cards on the god base have used this kind of video memory. GDDR6 also has a frequency-boosting performance-enhancing version of GDDR6X for some high-end discrete graphics cards.

GDDR5, and the omitted abbreviations are added to the GDDR5 Sgram, which is Graphics Double Data Rate Ver 5 Synchronous Graphics Random Access Memory. This is a high-performance DRAM (Dynamic Random Access Memory) designed for graphics cards that require high bandwidth.

The most frequent graphics cache available! It's not the same feeling as DDR3 in memory! It's just the 5th generation of graphics cache!

DDR Gen 5 Video Memory The best video memory out there.

GDDR3 is generally 1000MHz+ frequency, and now the improvement of the process is generally around 1600MHz;

GDDR5 is a frequency above 3500MHz;

With the same memory bandwidth, the read and write performance of GDDR5 is more than x2 of DDR3, and GDDR5 is more than x2 of DDR3 GDDR3 frequency.

GDDR3 uses 80nm process, while GDDR5 uses 55nm, and the improvement of the process reduces the size of the chip, and the heat can be much lower;

GDDR5 memory chips provide three times the total bandwidth of GDDR3, and GDDR5 graphics cards have greater flexibility and performance improvements.
