Re: 486 DX-33 question
Posted on 2017-11-02, 14:24
TDP isn't really important, since you need to keep die size and transistor count in mind. It still get's very hot and heat must be dissipated. Otherwise, hot spots may emerge which can kill the CPU. 4.5W is like a tiny light bulb, like the ones you use in a bicycle. Really, it's no big deal, …

Technically any 486 CPU bellow 50Mhz. does not require a heatsink. But heat is a big enemy of electronics so it would be nice to have some cooling. You should see things in the proper perspective though... A 33 MHz 486 has a TDP of 4.5W: http://www.thinkwiki.org/wiki/Intel_486 4.5W isn't exactly …

Thanks for the explanation! :) So I assume it's not possible to write a software-based TSR that uses polling method to monitor a given i/o port and then sends a copy of that data to another location ? Not without patching the software. However, for the Tandy sound card we had a similar issue: …
Re: getting a floppy drive to work on a 486
Posted on 2017-11-01, 22:46
Most AT and newer systems will use the standardized 'twisted' floppy cable, where all drives have to be configured as drive 1 (B:, not A:, which would be drive 0). You connect the drive you want to be A: after the twist, and B: before the twist. This will be how your 486 works. See also here: …
Re: Someone have tried those cheap ebay VGA2HDMI converters?
Posted on 2017-11-01, 16:29
I have two of those cheap VGA2HDMI devices, and they work like a charm for me. They convert everything to 1080p. 320x200 is actually 640x400 on the cable, as mentioned, and that was no problem.

Yes, if you have a regular case with a PSU with a fan, there should be enough airflow for a 486DX-33. These were some of the last CPUs to not require any heatsink or fan. I don't think there is a way to monitor CPU temperature with software. This requires a temperature sensor in the socket, which …

Re: hyper threading is only slower
Posted on 2017-10-28, 21:03
I don't think using synthetic tests like PassMark would give a very accurate representation of what HyperThreading can do for you in real applications. As long as you use a HyperThreading-aware OS (that is Windows XP or newer), HT can go from a small performance hit worst case to 20-30% in good …
Re: Modern PC vs PS4, Xbox..

It looks like Wolf 2 is another new game that benefits a lot from >4GB video RAM. Look at the 1060 and RX 470/480. Also, it runs on ID Tech 6, so I assume its Vulkan-path has AMD-specific optimizations like DOOM 2016 has, making it invalid as an apples-to-apples comparison. Which brings me back to …

Re: SBVGM (DOS) VGM Player

Hi Scali! SBVGM uses that method to detect if a Game Blaster is present, but that method doesn't seem to work for Sound Blasters with the C/MS chips present. Ah, perhaps that is a shortcoming in the SB design then. By the way, are those Game Blaster clones easy to come by pre-assembled? Not as far …

Re: Need help identifying a Geforce2 GTS Pro
Posted on 2017-10-15, 15:34
The memory clock throws me off a bit. According to GPU-Z it is ~180MHz (DDR). From what I've seen, a GTS is 166MHz and a GTS Pro runs at 200MHz. Modern cards throttle memory speed but I don't think older cards did. I'm wondering it this card does and boost up to 200 when gaming (I'll test that …

Confirmation bias that is confirmed by real world application results. Sure. Yes. You see... the bias is not in the results, it is in how they are being interpreted. Your interpretation being that NV has "software" or "pseudo-hardware" implementations of async compute as opposed to "true compute" …

But with things like c and API, you really don't need to know what the hardware can do, just its limits. OR that's how I look at it. You would though, if you want to make informed statements about async compute and scheduling, since that happens at the instruction level. As I say in my blogs, async …
