While all of this is true one of the biggest reasons why Rambus failed is that in the PC industry standards are not owned by any one company. Rambus had patents on all of it's hard ware. Meaning if you wanted to make Rambus compatible hard ware you'd have to pay them a licensing fee. Basically they were trying to corner the market on ram/memory.

The RDRAM on the N64 use a 9bit bus to save on traces even more (the extra bit is meant for parity, but the N64 use it for anti aliasing). It is fast if you want to read just the next byte and the next byte etc.. you just go read-read-read-read and the memory has this internal address pointer thing that increase automatically. But if you need to do random memory accesses, you need to change the internal address, and that takes like 4 writes, so it's very very slow. And if you have the CPU and video chip fighting over the memory address, things gets very slow

N64 RAM is slow. AFIFAK N64 has ~0.5GB/s memory BW (same as Pentium 2 - could have 0.5GB/s with SDR-66 memory and 66Mhz FSB) Those 2 came 1996 (N64, in US and JP) and 1997 (N64 in EU and Pentium 2). Even worse, Pentium 2 has all that memory bandwidth for itself (without GPU) and it also has 256k-512k of L2 cache, 16k L1I, 16k L1D caches where N64 shares bandwidth with GPU, has no L2 cache and only has 16k of L1I, 8k of L1D caches.

It has been fun seeing all these home brew hackers figure this out in far greater detail that what was available in the 90's. Recently they have shown there are undocumented registers that show when the CPU/GPU are active or not. Turns out he CPU is idle about 70-80% of the time and the GPU is idle about 60-70% of the time. This is all due to it waiting on the RAM. Could have really used that info back then! Most of the visual edge on the N64 was handled via additional core functionality and internal caches. Reality Engine and its functionality (Texture filtering, proper perspective calculation, actual understanding of depth via a Z-buffer!) was basically the only thing stopping the N64 dropping down to Ps1 performance.

The reason RDRAM, despite being tricky and expensive to manufacture, was cost effective for the N64 was because the console only had 4 MB of system RAM, which could be expanded to 8 MB with the Expansion Pak. When the Pentium 4 came to market, 512 MB was rapidly becoming standard for high end PCs, and 256 MB of RDRAM was much more expensive than 512 MB of SDRAM. Intel tried to alleviate that by including a stick of 128 MB RDRAM and a continuity module with the Pentium 4, but even this didn't help increase sales, and they ended up giving up this exclusivity by 2001. Also, the reason Intel chose RDRAM for the Pentium 4 was due to its many architectural... Umm... Characteristics. Lol. Well. It was much more bandwidth-dependent than previous architectures due to a much deeper pipeline and a very fast but very small L1 trace cache system, so RDRAM's bandwidth advantages would keep the caches and the pipeline well fed. In fact, P4 shows a very mediocre performance when paired with SDR SDRAM. This of course was reversed since the introduction of DDR SDRAM. Fun fact: Intel also supported RDRAM with some high end Pentium III chipsets. In fact, they were the only ones that supported a higher speed AGP bus version for a while, which of course made people really mad. Intel eventually also gave up here, and soon they released a high end chipset that supported traditional SDRAM, as well as this faster AGP slot. And, since P3 didn't have the same bandwidth hunger as its successor, the performance gains with RDRAM were minimal.

However they also faired just as well with a ddr based MMC, better in some corner cases and better with rdram in a few more corner cases. Money changed hands or Intel would likely have only used RDRAM based P4's for specialty scenarios and big iron where they could put a lot of rdims together for a wider buss.

Something else worth noting is that all modern hardware benefits from wide busses, the narrow 16bit bus might have been nice in the 90s, but due to latency issues, and the shift to 64bit systems, with SSE and AVX, it's pretty much required to make multiple requests to memory to fill a 256bit wide SIMD instruction, and for prefetching to prevent stalls waiting for memory, Factorio can gain some substantial performance (20%) by increasing the default paging size up from 4KB (only really possible on Linux).

Explanation of double data rate: The clockspeed here refers to the wavesignals waveform, so from rising edge to another rising edge. As far as instruction cycles or logical cycles go the line needs to of course be read twice per each cycle. So in that sense its not double rate. The advantage from using both the rising and falling edge to transfer information comes from how alternating current introduces design problems as the frequency rises. Impedance and phase shift are porpotional to the frequency, meaning it becomes the limiting factor. But if you use both the rising and falling edge to transmit data you still have to hit the same timings on low and high peak, meaning the second bit of information is ”free” as far as designing the bus lane goes. The devices still need to act upon the lane twice as many times as usual, else they couldn’t distinguish between rising + falling edge and no pulse. As far as I understood it they don’t get the second bit of information for ”free”. But that’s fine, because the long bus lanes and their signal intergrity is the limiting factor, not the devices at each end or their logical clock speeds.

The semi-official spec PC1066 RDRAM modules were the fastest memory option for the newly-launched 533FSB Pentium 4's in spring 2002. Only problem was these modules were super expensive, hard to find and only a handful of enthusiast/workstation-class motherboards could actually run them at their rated speed. Within just a few months, the launch of dual-channel DDR SDRAM boards made RDRAM obselete.

The biggest thing missing is as I recall had to do with RAMBUS single channel vs duel channel. In the PC world at the time, RAMBUS was promoted as faster, but required the second channel to achieve the best speed. RAMBUS single channel was suggested as an economic solution for budget PCs. RAMBUS actually made budget PCs more expensive and slower than DDR at that time. That single channel made it into almost all PC's that used RAMBUS. That is why RAMBUS was slower in perception and in reality.

Can you explain why ram signals can't be multiplexed or why a bus can't be optical where different interconnects can't use the same bus on a different frequency/phase rather than shutting off the bus while it's in use? It's incredible to me how fast Ethernet has gotten so damn fast over the years by doing this, but ram takes massive power and specific slot placement, channels available depending on sticks installed, bios profiles and all that. It seems crazy to me how slow ram is tbh. Also, why is ram built into the motherboard on high end boards? Solder 4gb of hbm next to the cpu and let sticks be added for when that mobo ram fills. Even if it only runs system and os, a level 5 cache measured in gigs would absolutely phenomenal even if only the os used it to help speed up the chipset io. Chipset hbm buffers would be amazing!

If you’re talking about straight up throughput, then yeah, ethernet is faster. But that’s where it ends. RAM is _orders of magnitude_ lower latency than Ethernet (a million times lower, to be exact). Ethernet latency is measured in milliseconds while RAM latency is measured in _nanoseconds_. Why is Ram situated as it is? Latency. At that scale of latency minute differences in the length of traces materially impact the latency of one bit vs the next. Traces need to be the same length to keep the latency consistent. CPUs/GPUs need to switch between instructions far, _far_ faster than Ethernet could ever even dream of being able to provide the requested data for. Sure, compared to RAM, Ethernet is analogous to a fire hose vs a squirt bottle. However, try changing the direction of a firehouse as fast as you can a squirt bottle. All that throughput is useless if it takes comparatively forever to retrieve it. Besides all that, Ethernet and RAM are two completely different things, they’re not interchangeable. As for HBM with extra cache, that’s somewhat the direction things are going in, but HBM alone sends complexity through the roof, adding an external cache to the mix just multiplies the complexity to be (currently) out of the realm of practicality for all but the most demanding use cases. There’s a reason those high end boards you mentioned are high end: it’s not due to the presence of it, but rather due to the complexity required to have it there in the first place (and have it work in a beneficial fashion).

Not having to buy ddr in pairs is why some computers are slower. Worhout that second stick you don't get dual channel. 1. Some users are not informed enough and end up buying one 32GB stick insted kf two 16GB sticks 2. Some manufacturer only put one stick in their laptop making it preform worse plus they sometimes don't give you an option to add a second stick so you are stuck that way. 😡

Remembering my first (and Last) RDRAM-Machine A P4-3200 HT 533 Asus P4T-533R But just 4x256MB RDRAM 32Bit 1066. I would have it till today, but I couldn't find any 512MB Modules for Years. So i sold it, before I lost to much Money. But I loved this machine and from my perspective, it was fast as hell (at that time). But only 1GB of RAM in total couldn't keep up with the needed ressources that came with Windows XP.

Most of my stuff is still DDR3. It's okay because I'm a retro sort of guy anyway. Yeah, I went on a bit of a used office-PC buying spree when third and fourth-gen Intel machines were the ones to get a while back. They still do their thing quite well. I remember when all the Rambus controversy was happening. I remember it was not well received on the tech sites I checked. Opposition to it seemed overwhelming from the user side. The nice thing from the user side is that AMD was there to go in their own direction so Intel and Rambus couldn't try to brute force this arrangement once it became clear that no one was happy. As I recall, I got a computer a little bit before, and shortly after all this, so I was able to sit the whole thing out and never dealt with Rambus stuff.

"allowed it to run at faster clock speeds" no, it was required to run at 8x the speed to keep up with the baseline minimum that other technologies of the time were able to produce. that's like saying your 8-bit cpu can keep up with a 64-bit cpu, because it can run at 8x the speed, while conveniently leaving out the fact that 64^2 [4096] is greater than (8^2)x8 [512]

RDRAM had been around since way before the Pentium 4 era. Expensive as fuck, but I remember a friend building a dual CPU 200MHz Pentium Pro (the precursor to Pentium II) workstation with RDRAM. He had found a second-hand dual CPU motherboard and a single Pentium Pro processor for rather cheap, and the memory modules became the most expensive part of that build. A lot more expensive than other contemporary RAM sticks. It wasn't until some years later that they seriously tried to push RDRAM to the market, and it then was a quite shortlived fad.

Intel also wanted to introduce a "new" atx12vo standard, and I'm glad that the manufacturers didn't fall for those brats who constantly change the processor socket to sell "new" (refresh) chipsets

Pentium 4 was really much faster with Rambus than with standard SDR memory. Due to the exclusivity deals though, Intel couldn't make boards with DDR. Their 845 was a slugfest. That forced them to help SiS make some seriously good chipsets with DDR compatibility. The moment Rambus deal ended, they created the 845D and threw SiS under the bus. Which really was expected.

I the first computer that i could call Mine, was a Dell pentium 4 (first gen) with RDRAM. Finding ram was fun becuase it came with 2 modules and 2 dummy pairs. had to find matching sticks to the ones i had. Also when i looked to upgrade the CPU they had already changed the socket type in ( gen 2 i think P4), so the only upgrade i could get was from i think 1.3ghz to 1.5ghz. so my next computer i got was an AMD 64 x2.
