Sapphire has introduced one the industry’s first Radeon RX 570 graphics cards that carry 16 GB of GDDR5 memory onboard. The board is designed primarily for cryptocurrency mining, but it still has a display output and therefore can theoretically be used for other applications too.

Officially, the manufacturer positions its Sapphire RX 570 16GB HDMI Blockchain graphics card for Grin coin mining, as Grin's underlying algorithm benefits from the amount of onboard memory.  This gives a 16 GB video card a distinct advantage on Grin. The card consumes 175 W (±10%) of power and has an 8-pin PCIe power connector, which is 25 W higher when compared to “regular” Radeon RX 570 GPUs that are rated for a 150 W TDP. It uses an air cooling system that is comprised of two fans and a large aluminum radiator with heatpipes.

Sapphire plans to sell its RX 570 16GB HDMI Blockchain graphics card directly at, and it remains to be seen whether the adapter will be sold by third parties. Interestingly, the board vendor has not disclosed pricing for the board, and given the unqiue market for the product I suspect it's going to be based on the quantity of the boards purchased. Though the company does note that the product will cost significantly less than other graphics cards carrying 12 or 16 GB of memory (e.g. Radeon VII, RTX 2080 Ti, and the like), which is logical given the positioning of high-end GPUs for prosumers and professionals.

In addition to graphics cards for miners, Sapphire also sells its INCA and MGI-series systems for cryptocurrency mining.

    This to 11. Autoplaying videos on my metered internet connection on mobile just irritate me. Please stop this madness. Also, taboola is what drives me to no longer use chrome on mobile and switch to Firefox with adblockers. Those are starting to fail me too, now. Reply

    Forgot to mention - I'll pay $50 per year (MAYBE $100 per year) for this site, as I use it regularly enough, if you provide the option for a no ad version. Reply

    Just remove the autoplaying video in the middle of each page and I'm good. I don't mind having ads to support a site, but that one is a real bother. Reply

    This reminds me of an article I read on Tom’s Hardware years ago. They had the nerve to publish an article calling readers who use Adblock thieves. Their ads were obtrusive and in-your-face kind, much worse than ads on AT. Browsing TH on mobile devices was almost impossible. And that was the last time I visit TH after being their loyal reader for years.

    If a website wants to make money to keep on going, they should have visitors pay for subscription or have limited number of ad banners. Header and footer ads are acceptable. Not the hijacking, malicious, power hungry ads TH have on their site. They are the thieves for slowing down my device, consume my precious battery power, stealing my screen estate and my time with their obnoxious ads.

    If you think the ads are too much, there’s an adblocker called 1Blocker for all non-jail broken iOS devices on AppStore. For Android, just root and install Adaway and everyone knows Adblock Plus for PC.

    On Android, I just shut down javascript in the stock browser most of the time anyway which has the side effect of shutting down just about every modern attempt at delivering advertising content and blocks a lot of the other nasty stuff that lurks in most websites. Anandtech takes far too long to load on my little old quad core phone with js enabled anyhow.

    As for Tom's Hardware, I sympathize. I started using THG back in the days when Tom Pabst was still running the site (around 1999 for my readership IIRC) but advertising was what drove me away. I've been spreading my tech news reading out among other sites aside from Anandtech following the auto play video business in an attempt to find a new default tech news source. It doesn't matter that it can be blocked or not. I'd rather spend my time on a site that exercises prudence when it comes to advertising as that is now just as important as the journalism and content.

    How did they double the memory for the part? Did they just happen to have DRAM that's twice as dense? Since the memory bus is fixed, that's the only thing that would make sense. Unless they increased the number of devices and it was already designed with an addressing bit for multiple ranks. Seems like it would be low volume and high enough labor that just buying a more expensive (highend) card would be cheaper. Reply

    GDDR5 includes a feature called clamshell mode. Essentially each chip is put into 16-bit mode and shares a 32-bit memory channel. This doesn't improve performance at all (there's no additional memory bandwidth), but it does double capacity. Reply

    Thanks for that useful info. I didn't know that. Reply

    Am I the only one who doesn't know what the hell Grin is (aside from being a scam/cryptocurrency)?

    Or is everyone just ignoring that elephant in the room?

    I've learned to just Grin and bear it. Reply
