Tomb Raider (1996) meets Cyrix 5x86-100GP (Part 3)
Рет қаралды 44,070
Күн бұрынPart 3! Finally we can try Tomb Raider on a CPU clocked at 100 MHz: a Cyrix 5x86! This CPU has a few surprises waiting for us. Not only does it come with some hidden features, it also is supposed to be as fast or faster than a Pentium 75. The system requirements of Tomb Raider state a Pentium 60 to be the minimum CPU that should be used to run the game. But how true are those claims about the Cyrix CPU to outperform a Pentium really? We will find out today!

You can achieve better framerates with S3D accelerated Tomb Raider patch. I've got minimum 12 FPS (in more complex areas) with Cyrix 5x86/100 with all features enabled (in 640x480) with overclocked S3 Virge DX (by mclk tool). BTW. Washed black with S3 Virge is a software problem. You can overcome this by using video bios 2.01.07 (or 2.01.08). Anyway great content as usual :)

Nice! I will try a new BIOS on this card then. I spent no time investigating the issue - I guess I was looking for a reason to finally upgrade the Tseng cards :D And I will also try the S3D patch in the future - but probably in a single video. This series must finish with 3Dfx 😊

Watching you painstakingly straighten each pin on a CPU or re-soldering a broken pin on a socketed chip is amazing. It's great to see someone spending so much time and care on these old things. They'd definitely be thrown out otherwise, and you can't replace that once it's in a landfill. Great work too, the pins on those CPUs you worked on in this video looked almost factory condition when you were done!

The image quality issue on the S3 sounds like a capacitor issue of some sort on the RGB pins. I'd try replacing those caps or decreasing the capacitance. It's a similar story to that of the SCART cables for PS1 vs PS2 where the PS2 cables have caps on them. When you use a mismatched set of cables, you end up with wrong brightness on the image in general. EDIT: just read another comment saying it's a VBIOS issue lol

Did build x686 after. It was great times.

That was quite a step up from the previous CPU. Please see if it overclocks to 120 MHz and how well it scales with frequency! If Peter's results over at CPU Galaxy are any indication, the 5x86 with special features enabled should give the X5 quite a run for its money! They're almost evenly matched in Quake and both have the potential to overclock by about 20%.

I have a collection of 100 CPU's from 386, to modern i7's, but only one Cyrix MII - 233GP. Precious metal scalpers have absorbed too many of them, as well as Pentium Pro's. Those fools would've made a ton more money, selling the actual processors that will never be manufactured again. I regret every piece of retro I failed to preserve, and I miss every system I sold off. Should've kept every little screw, because once things start failing - you need spares. These days I get every item in pairs, knowing that one will eventually become a parts donor, or troubleshooting duplicate. I never ran a Cyrix. Been an Intel guy for 35 years.

I would melt half the socket if I wouldn't have access to a microscope. I can imagine that your experience must have been frustrating! Hm, regarding heating the pins - I am really not convinced that it would help. I heated the donor AMD 486 in my previous video where I tried to harvest a pin. But those pins didn't feel any different. All I did was burn the wooden protector on the microscope base. I really doubt that 200 degrees makes any difference when bending those pins, but I might be wrong. I'm just afraid to constantly keep the temperature up, burn my fingers all the time, and prolong the process. If I would break off pins constantly, I would definitely try heating them, but so far, I don't see the need for it.

During big areas, to improve framerate , i`ve used "-" button to shrink image to a size of 5x5 cm or something. Now it sounds like some crazy stuff, but in 1996 this game was WAAAY ahead of everything on the market, so I just could not stop !

The Cyrix 5x86 has a much faster FPU than the AMD 5x86. With 100MHz it scored 20% better in the Landmark FPU test than the AMD part at 133MHz and I remember a similar result with the CPU-Z benchmark in Windows 98. But these were the only benchmarks I found where the Cyrix was better at stock clocks. With the Vogons recommended CPU registers and at 120MHz the Cyrix chip was much faster than the stock AMD 5x86 in every single test I ran. Sadly my AM 5x86 didn't post at 160MHz, so that would probably swing the favour back to AMD. On the other hand the main goal of the series is to run a 3D game, so maybe the FPU is king.

@@bitsundbolts no, i just used the pretin on the cards. It's older solder, so its not PB free and great after years. Just used flux and cleaned the oxidation of the socket-pins a bit with a fiber pen. I practiced on old 3com-pci-cards. Some of them were missing the bootrom socket. Or you can remove the old one, tin the pads again (no wick afterwards!), put some flux on it and then the socket. Try around 250°C hotair and give yourself and the board time to heat up, it takes a bit longer on this lower temperatures. If it's not working after 1-2 minutes, raise the temp by 5-10°C. You will soon see that the solder melts before the plastic and you can mount these sockets without a problem.

Interesting look at this cpu. I knew it existed and it could be faster than the amd 5x86, but I never saw one for sale. I was probably better having the amd 5x86 at 150mhz anyways, since I doubt I would have known about the extra flags that needed to be set, at least at that time.
@bitsundbolts 6 ай бұрын
I think you did well with 150 MHz AMD and didn't miss much. Plus, the Cyrix may be unstable if you run windows using certain flags. I'll try my AMD at 160 MHz (4*40). but it may even be slower than yours at 150 (3*50).

Would heating the CPU make the pins less likely to break when bending them back?
@bitsundbolts 6 ай бұрын
I don't think so. The pins would just be hot and I would burn myself while working on them. I might be wrong, but you're definitely not the only person who asked this question. In the last video, when I tried to get a pin off the bromek AMD CPU, the ceramic and pin was so hot that I couldn't touch the CPU. The pin didn't budge nor did I feel any change while trying to rip it off the CPU. So, I don't think that heat will do anything - at least not at the temperatures I am willing to expose the CPU to.
@dant5464 6 ай бұрын
@@bitsundbolts ah, I was thinking perhaps it would make the metal softer and more likely to not break. But perhaps it would have to be so hot that it would make this unfeasible and maybe even damage the chip.

I am curious as well. I did read somewhere that the AMD 133ADY was supposed to be a 160MHz version. So, I wonder if I should just overclock it for the next project. I mean, there is not much else in terms of CPUs I want to test - except the POD. I should do another video dedicated to overclocking those CPUs on a different motherboard that supports EDO RAM - I am running FPM on this board because it doesn't boot with EDO.

@@bitsundboltsI know some AMD 5x86 are actually faster than they are rated, maybe it was cheaper to rebrand as a lower sku? Will be interesting as clock for clock the Cyrix in theory should be faster at the same clock speed but they often clock lower than the AMD cpus. Also wonder how much difference EDO and faster ns ram makes; i know cache and ram makes a slight difference with a Pentium overdrive.

Ahh the 5x86, also known as the disappointment which any kid who tried to run the demanding games of 1996 - Quake particularly - would tell you. This era was full of them, bold promises in magazines lured you in and in some limited scenarios maybe they were just as fast as Pentium... just not the scenarios you wanted. We also didn't know about the disabled features or at least I never met anyone who did, this kind of knowledge really wasn't so widespread back then. Despite this I owned a 5x86, a 6x86 and a K5... of them all the K5 was the most honest but still had its failings.

@bitsundbolts 6 ай бұрын
The 908 chips should have 1MB and the 909 chips 1.125 MB - which would give 2.25MB with two chips and 4.5MB with 4 chips. The last digit 9XX defines how many MEGABITS are available. So, for the 909 chips it would be: 9*1024*1024 / (8*1024*1024)=1.125. I have the 908 which is 1MB. Anything above 4MB seems to be wasted on the Tseng ET6000.

Other tidbits i've found: Am486 (usually) have 8kB L1 cache, 5x86 have 16kB L1 cache. Usually. If the suffix contains "16", it has 16kB of L1 even if it is 486. (ex. -133V16BGC, -120NV8T)

I'd use 0.5mm or 0.7mm mechanical pens to straighten pins. Works 99% and it's way faster method imo. If I remember correctly Tomb Raider is _almost_ playable w/ 40MHz FSB. 120/40MHz and overclocked VGA-card like Cirrus or S3 helps a lot. But it ain't pretty w/o 3D-accelerator as we all know. I had Matrox Mystique and it was ok speedwise, but 3dfx looked way better of course.

The takeaway is, write-back delivers slower performance without turbo if you're looking to slow down your system for a certain task (e.g an old game). All comments are welcomed!
