It looks like SiFive is making a vector processor, to potentially compete with GPUs (Nvidia makes chips with dozens of multiprocessors on them, each with arbitrarily many cores)
I’m getting confused. You mention this is a product to eventually compete with GPUs. So is this a quasi-gpu that’s being announced? Will there be a opengl or vulkan driver to interface with it? Is this a regular accelerator? Your comment does not add much clarity.
If it is in fact a CPU designed to be used like a GPU, that’d be very akin to Intel’s (dead) Project Larabee.[0] As I understand it, it was supposed to be a GPGPU[a] that internally was just an x86-64 processor with massive vector units. So, in theory, one could offload practically an entire game onto a Larabee card (save for IO probably) and do computations there. Compare that to a GPU where computations must be sent back and forth between the CPU and GPU.
Linus Sebastion (of LinusTechTips) managed to get his hands on one and made a video on it.[1] It’s been a while since I’ve seen the video, but, IIRC, they weren’t able to get it to work, so the video was a bit of a letdown.
Sounds like an additional core you can get from SiFive and a follow up to their previous Linux capable board with something more capable. Not sure what's "constant hype" about having hardware to buy or vaguely described in the article?
What is "R-V"? Please use correct non-ambiguous terminology.
The press release says nothing, but 740 suggest it's based on the 74 which is a dual issue core with the vector extension. The latter is a big deal (basically doubles the silicon area for one metric), but ISTM that it's not the OoO core, so not in the same class as eg. BOOM.
It's not clear to me. The big new thing in the 74 core is the vector extension (thus, RV64GCV) and in the context of the question it might very well have been that the OP was asking about. Clear and effective communication benefits from the absence of ambiguity lest we just end up with a bunch of TLAs that ATM seems FTW, but might raise a "WTF" for someone else. YMMV.
Did I touch a sore point when I wrote R-V? From your reaction It seems like I did.
Is the term R-V perceived as detrimental? Does R-V not sound cool? I think it does.
Super exciting!
