Trouble with modern consoles (games, graphics if you will) is which RAM? Most of content is loaded into and needed on GPU RAM, not system RAM.

- baldfat 10y agoThe ability to increase the GPU Ram has the same possibilities, but is VERY expensive right now. a 24GB graphics card cost about $5,000 and most of that is due to who currently needs high GPU Ram. These are for Scientific Computing and Data Analysis and boy I would love to have one. Image having these on your Spark Servers and using all the fast GPU Ram? http://www.newegg.com/Product/Product.aspx?Item=N82E16814132041&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Video+Cards+-+Workstation-_-N82E16814132041&gclid=CjwKEAjw7ZHABRCTr_DV4_ejvgQSJACr-YcwzESrzN4lVcBTdKK6KZykAq2y8vuVOVRPVOHNuASItxoCHjbw_wcB&gclsrc=aw.ds http://www.newegg.com/Product/Product.aspx?Item=N82E16814132...
- Keyframe 10y agoWe have a couple of Quadros with 12GB at work. They aren't really fast compared to GTX, but dat RAM makes a difference. We really need to have RAM revolution on GPUs.
- valarauca1 10y ago>> modern consoles (games, graphics if you will) is which RAM? Except the modern console generation doesn't have dedicated GPU RAM. They are using AMD APU's that unify System/GPU ram.
- Keyframe 10y agoYou're right, with on PS4 it being GDDR5. It leaned towards graphics, not system, requirements. Not exactly the breed you'd find in regular stuff.
- valarauca1 10y agoThe primary difference between GDDR and DDR is 128bit vs 64bit bus. GDDR is also normally SRAM, but DDR can be SRAM, but it is normally DRAM. Saying one is geared to graphics is just marketing.
- Keyframe 10y agoSo why did they choose GDDR then?
- valarauca1 10y agoI'm not Sony Engineering so IDFK GDDR5 trades latency for thoughtput XboxONE DDR3: 68GB/s CAS 7 PS4: GDDR5: 127GB/s CAS 15 The reason GDDR is normally used in GPU's is the workloads are more predictive, you are doing the same calculation thousands of times, just iterating across a buffer. This is why SIMD/Cache prefetching shine in GPU's. It makes memory latency not as important.
- Keyframe 10y agoSo, you're saying GDDR is more geared towards operations done commonly in graphics? ;)
- valarauca1 10y agoNo. I'm saying it is gear to work loads with easily predictable or cache-able memory access patterns.
- xenadu02 10y agoI think you meant SDRAM not SRAM?
