Will HBM benefit the gamer?

post #1 of 3
Thread Starter 
Although HBM promises a lower energy consumption for greater bandwidths, this is only part of what makes video card. The GPU itself with its thousands of cores is where the 'action'is. Just because a video card uses HBM, doesnt mean it will be faster, or will it? Is the thermal throttling that occurs in a video card from the GPU heat or the memory heat? And as for the the 'high bandwidth' component, do games really tax the already amazing 8 gbs bandwidth of GDDR5? Isnt high bandwidth really beneficial for servers where thousands of processes are being executed in parallel? Yes I know most server events occur on the CPU, not GPU, but I am trying to understand in which scenarios high bandwidth memory will be most useful.

The higher bandwidth of HBM is couple with slower frequency so it seems to performing similarly at the moment to GDDR5. Itll get better with each revision like DDR has.

At the moment it probably benefits gamers on their electricity bill. Down the track I guess it will mean much smaller, more power efficient graphics cards than what could be built with GDDR5.

It will probably come to the point in a few years where a beast gaming system with multiple GPU's will fit easily in a mITX case with a 300Watt PSU tongue.gif

In a word, yes.
  • At high resolutions, HBM is a direct benefit due to the volume of pixels (especially >4k). High resolutions need a lot of memory bandwidth.
  • For VR, HBM can also be beneficial in sustaining the smooth experience (VR is very sensitive to frame rate drops and needs high resolution to work well). Again this is bandwidth intensive.
  • By reducing power consumption, more cores and other components can be put on the die, because there is less need for a hot memory controller

While most GPUs are not memory bandwidth constrained, HBM has a variety of uses, especially for high end gaming. For low end gaming, not so much right now because of the cost and complexity, but as time goes on, HBM should get cheaper and more widely available.

A potential application if HBM gets cheaper is APUs - right now the integrated graphics on them is heavily bandwidth constrained and APUs cannot justify the cost of a quad channel RAM platform (many don't even have dual channel RAM). HBM potentially solves this problem, provided it is cheap enough.

The other reason is that GDDR5X will eventually top out, as will GDDR6 (if there is a widely adopted follow-on, likely based on DDR4 the way GDDR5 was based on DDR3). Wide and slow is the future. The other is that color compression is likely at some point going to hit a limit as well as to how far it can go. That means that something like a wide-slow architecture will be needed.
