SIMD in Context: The Bandwidth Problem Part I

In the previous entry, I espoused and showed how AVX could produce a whopping 10x performance improvement for 1 specific workload in a game engine and showed mathematical proof of correctness for the algorithm. However, I did not show how the solution compares to accelerating the task by multithreading the scalar code. I also only briefly mentioned why the SIMD code would have memory bandwidth limitations. However, I haven't actually fleshed either issue out. This entry seeks to start that for t

Retro Gaming: EA's Jordan vs Bird

Jordan vs Bird was more popular on consoles, you might best remember it either on the Amiga or NES. This is really a piece of my early DOS gaming history and first EA game of that era. Back then I was a fan of Sierra games so this EA game was a rarity since I preferred the NHL Hockey series when the mid-90s arrived.   Front of the box with the retro EA logo:   Back of the box with a fairly close example of how EGA graphics looked back in the late 80s and the computer req

List of Guides I've Written

A list of guides I posted somewhere on the site, just in case I post more than the 10 URL limit for profiles (plus that'd get wild anyway)     A guide to how to identify if you have a CPU bottleneck and see how much it can affect you.   An explanation on HyperThreading.   It also answers the question "Why is it bad to have no page file?"                     Not really a guide, but might be hel

Why I find Windows 7 to be a better OS than Windows 10

After I used Windows 10 as my primary OS for many months, I realised that I wouldn't miss anything about it if I went back to Windows 7. And since I found that everything was more difficult, more frustrating, more ugly, and more time-consuming on Windows 10, I went back to Windows 7 as my primary OS. Windows 10 made the detail of just having an OS a chore and liability all on its own, whereas Windows 7 is just passively there, like an OS should be, and just works for whatever I decide to do, wit

A look back at the gadgets and gizmos I've had over the years

I usually try to avoid buying the latest and greatest technological thing that's "in". Like when smart watches were all the rage last year, I avoided them. When the iPad came out, I saw it more as a novelty. I avoided wireless things, since I didn't want to deal with charging them up and such. But all that's changed, since now I've owned these kinds of products (well, except the iPad). So here are my thoughts about the gadgets I've purchased over the years, and whether or not they're still impor

3Dfx Voodoo 3 3000

Couldn't resist taking a photo of the card and the box.  This was originally in my former Pentium III 550Mhz desktop, if I recall this card was last used in my Athlon 64 before I got my hands on a GeForce 6600GT.

Is PC gaming really cheaper than console gaming?

Oh boy, I'm going to stir up the hive with this entry.   I found myself in a discussion on another gaming website where the article was originally for discussing the PS4 Neo, and the comment train went on discussing the implications of if consoles do follow the hardware refresh model like cell phones and such. Or rather, if you're going to have to spend $400 on the latest and greatest thing, doesn't this drive the value of console gaming down even more? So I want to look into this topi

I want to see autonomous cars fail more.

I came across a YouTube that had a video that explained two points. What causes traffic Why autonomous cars are better I recommend watching at least the first half because it has a few scenarios that causes traffic, some of which are semi-preventable. And you should watch it. And you should apply that to your own driving habits.   Anyway, the later half talks about how autonomous cars solve this problem. But if you skip to about 4:04, it shows autonomous car

It's strange to think people dislike the PS4 Neo and XBox Scorpio...

A few articles that popped up on my news feed are kind of upset over the idea that the new business model for consoles from here on out may be to shell out an upgraded refresh every two years or so. That now they are copying the cellphone model and feeding on the drive that people must have the latest and greatest shiny thing, lest they look like an ancient old fart living under a rock. I don't really mind it so much, as long as they continue to not kill support for the older consoles until the

Custom PSU basement

I loooooooooove the look of the Corsair Spec Alpha black/silver but it's a budget case, so no PSU basement... I found this on LTT the other day:   So I'm going to do a similar thing with my Spec Alpha, I already have the metal and a cardboard model of what it's going to look like, I don't know when this'll be done, I just know I'm doing it.

Resources to fix issues with Windows Update finding and installing updates in Windows 7

If you installed Windows 7 using either a DVD, or an earlier ISO image of the Windows 7 installer, you might find yourself waiting for a long time searching for updates to Windows 7, after the installation has completed, and you've run Windows Update. I don't know how typical this issue is, but there seems to be a significant number who experience Windows Update searching seemingly indefinitely without finding, or starting to install updates. Sometimes just waiting long enough is the solution, b

Important tips that will help you grow your business mind

Train Your Mind To feel confident about the ability you have  One of the worst things we do to feel bad about our self is that we demotivate ourselves by saying that we cannot perform a particular time, and we are unable to do it because of a number of disadvantages in ourselves.  This means that we have lost the fight even before we make an attempt to win it.  If you do so, you will not only lose the fight but also lose self-confidence. The latter will shatter you, and you will h

What if larger monitors are like larger camera sensors?

No matter how I slice it, things look pretty on my 46" 1080p TV than when I see the same thing at 1440p on my 27" monitor. I could say it's because the TV is glossy while the monitor is matte and I do get some envy looking at iMac screens, but maybe it's something else.   So the relationship to monitors and camera sensors as the title suggests is that packing more pixels in a fixed area on camera sensors may actually produce worse image quality than not. The reason being that each pixe
