CPU of the Day: Motorola MC6801 – The (second) first 6800 MCU
Motorola XC6801L – Early White ceramic package from early 1979. XC denotes a not fully qualified part.
A microcontroller (or microcomputer) is a CPU, with additional on-board peripherals, usually containing RAM, ROM, and I/O as to serve as a single (or close to single) chip solution for a computer system. As the program space is typically small, they were designed and used for high volume, low cost, simple applications. Today we would refer to them as embedded applications. The Motorola MC6800, released in 1974 was a decent 8-bit processor. It was however not inexpensive (a fact not lost upon one of its designers, Chuck Peddle, who left to design the 6502). Initial pricing for the MC6800 was $360, dropping to $175 the next year.
For embedded use, prices needs to be in the few dollars range, with as little chips as possible required for a design. By 1977 Motorola had a solution, the MC6802. This MC6802 was an enhanced MC6800 128-bytes of RAM and an on-board clock-generator. When combined with the MC6846 (which provided ROM, I/O and Timers) a complete system could be built. Defective MC6802s were often sold as RAM-less MC6808s.
Motorola MC6802L – Dated March of 1978. The 6802 had 64-bytes of RAM and no ROM.
The MC6802 was followed by the more complex MC6801, which integrates the features of the MC6846 on die, making a true 8-bit single chip microcomputer. Most sources refer to the MC6801 being released in 1978, however it was actually released in 1977, likely at the same time, or similar as the MC6802. US Patent Application US4156867 filed on September 9th of 1977 references both processors. GM was to be the lead customer for the MC6801, it was the MCU of choice for the digital trip meter (TripMaster) of the 1978 Cadillac Seville. The 1978 Seville began production on September 29, 1977 on a 5.1um NMOS process. It is likely that all of the first production of the 6801 was reserved for GM, and it wasn’t until 1978 and later that Motorola began to market it (it begins to show up in Motorola marketing only in 1979). In 1979 the MC6801 also switched to a 3.9um HMOS process, which likely increased yields and decreased costs. The TripMaster was a $920 factory option that proved to be rather unpopular, likely due to it adding nearly $1000 in cost to a $14,000 car.
Motorola MC68701U4L-1 1987 6801 with upgraded RAM/ROM and Timers
This lack of early availability, coupled with the fact that while capable, the 35,000 transistor 6801 wasn’t particularly inexpensive led it to have very little success in the market. The EPROM version, the MC68701 infact is much more common, likely due to the fact that it was used in lower volume products, where cost wasn’t such an issue. In 1979 Motorola attempted to remedy this by releasing the MC6805 series. This was designed from the ground up to be low cost. The first versions had half the ROM and half the RAM as the 6801, while keeping the I/O. They were also available in CMOS (as the MC146805). They were inexpensive, and highly functional, and were widely used. The 6805 continues to see use today as the 68HC05 and 68HC08 series.
Motorola XC68HC11A0FN – 1987 – Preproduction, Enhanced 6801
The MC6801 was not, however, done. By this time manufacturing had improved, allowing costs to be lower. Motorola released an upgraded 6801, the MC6801U4 which expanded the timer functions, increased the ROM to 4K, and increased the RAM to 192-bytes. In 1985 the MC6801 was upgraded again, a second 16-bit index register was added, as well as true bit-manipulation instructions. The Motorola MC68HC11, the name change reflecting the greatly enhanced core, was made in many varieties with different sizes of RAM, ROM, and EEPROM. The MC68HC11A8 was also the first MCU to integrate EEPROM on die, in this case, 512 bytes worth. The MC68HC11 series, and its 68HC12 and 16 successors, continue to be made, and used today, ironically, frequently in automotive applications, where the original MC6801 failed to be a success.
Best CPU for AMD Radeon RX 6800 in 2020
Amd Radeon Rx 6800
(Image credit: AMD)
Both Intel and AMD processors will work just fine with the AMD Radeon RX 6800 GPU, but if you wanted the very best at launch, you’ll want to go with an AMD CPU for enhanced performance. While the Radeon RX 6800 isn’t the best graphics card from AMD, it can still make use of a capable multi-core processor. Here are our recommendations.
AMD Ryzen 9 5950X
Best Overall AMD
This monster of a processor is the range-topping Ryzen 9 with a whopping 16 physical cores and 32 threads. The performance is as mad as those figures, allowing you to plow through even the most demanding of games at 1440p and 4K. The Radeon RX 6800 won’t be able to test this CPU but at least you know that it’ll gladly be paired with a more powerful GPU once you upgrade.
Intel Core i9-10900X
Best Overall Intel
While you do need a specific Intel x299 series motherboard for the Core i9-10900X because of it being an X-series processor, it’s well worth it in the end. This 10 core and 20 thread CPU provides plenty of headroom in both single and multi-core optimized applications and games. It’s more than a match for the Radeon RX 6800.
AMD Ryzen 9 5900X
Runner-up AMD
This processor may be a small step-down from the Ryzen 9 5950X and is considered the «entry» point for the Ryzen 9 series, but it has an impressive 12 cores and 24 threads. These numbers are still ridiculous, allowing you to create an impressively powerful gaming PC. The Radeon RX 6800 isn’t the most capable GPU, but you’ll easily enjoy smooth 1440p gaming.
Intel Core i9-10850K
Runner-up Intel
Moving down the Intel ladder, we have the Core i9-10850K, which is only slightly slower than the Core i9-10900K we reviewed favorably. It still houses 10 cores and 20 threads, but the TDP rating and clock speeds are a little slower. This CPU is unlocked, however, allowing you to bump the clock speeds up and almost match the 10900K.
AMD Ryzen 7 5800X
Best Value AMD
A few years back you’d laugh to call an 8 core and 16 thread CPU «mid-tier,» but that’s precisely where we are right now. Should you want to save a little, but still enjoy quite the performance, the Ryzen 7 5800X is a good place to start. It supports PCIe 4.0 and comes rocking all the other impressive features from AMD’s 5000 series of processors.
Intel Core i7-10700K
Best Value Intel
The Core i7-10700K from Intel is much like the Ryzen 7 5800X in that it packs inside 8 cores and 16 threads, making it one fine mid-tier processor. This CPU does have a slight edge on top of the Ryzen 7 5800X in that it has ever-so-slightly better single-core performance. There’s also an integrated GPU, which makes this a better value proposition if you plan on saving a little for the Radeon RX 6800.
AMD Ryzen 5 5600X
Best Budget AMD
We’re now entering into AMD’s more affordable Ryzen 5000 series range with the Ryzen 5 5600X. The Ryzen 5 series became incredibly popular with PC builders due to its excellent price to performance ratio and the latest processor is no different. It has 6 cores and 12 threads, making this one amazing value-centric CPU.
Intel Core i5-10600K
Best Budget Intel
Intel also matches AMD with the Core i5-10600K, rocking 6 cores and 12 threads at a reasonable price. Should you already own an Intel motherboard or prefer these processors over AMD’s offerings, you’ll be able to save a little with the 10600K whilst also enjoying a solid gaming experience.

Choosing the right CPU for your gaming PC build comes down to what games you plan on playing. If you’ll be playing modern games at 1080p or 1440p, you likely won’t require anything above an AMD Ryzen 5 or Intel Core i5. More CPU-intense or demanding games at 4K will need something with a little more punch, which both Intel and AMD can offer. If you want the very best, go with the AMD Ryzen 9 5950X .
- RTX 4080 preorders and stock updates — Live report
As aforementioned, you likely won’t require all that performance, which is where the excellent AMD Ryzen 9 5900X comes into play. It’s a little cheaper, has fewer cores, but is more reasonable for gaming (and your budget). For an Intel motherboard and PC build, you’ll want to go with the exceptionally powerful Intel Core i9-10850K .
If you’re all about value, the AMD Ryzen 7 5800X is a great middle-ground that balances performance and price. The same goes for the Intel Core i7-10700K , which is almost as good as the i9-10900K sibling. There are other value options, too, if you feel comfortable with going for a processor with fewer cores and threads.
