The decades-long desktop CPU battle between team red AMD and team blue Intel continues to rage on…
The History of AMD vs Intel‘s Desktop Processor Rivalry
Ever since AMD reverse engineered the Intel 8080 processor back in 1975, the two Silicon Valley chipmakers have been bitter rivals. Both companies have pushed the envelopes of consumer computing power for over 40 years through cutthroat competition.
In the early days Intel took an early lead in the budding x86 microprocessor industry. The original Intel 8086 CPU in 1978 kickstarted the x86 instruction set architecture that would become the de facto standard for the personal computer revolution in the following decades.
AMD launched their first Intel-compatible Am286 clone in 1984, but continued trailing a few steps as Intel‘s pace of innovation kept increasing through the 80s and 90s. Intel‘s CPUs generally outperformed AMD‘s cheaper knockoff options that were relegated to budget builds.
This status quo shift substantially in 2003 when AMD launched their disruptive new Athlon 64 processor. It was the first mainstream consumer CPU to include 64-bit instructions and an on-die memory controller among a host of advanced features. AMD‘s innovation increased x86 performance by over 30% on average. Intel responded by licensing AMD‘s x64 extensions and playing catch up for years.
Over a decade later, AMD once again turned the industry upside down with their 2017 consumer processor comeback dubbed ‘Ryzen‘….
The Zen Microarchitecture Fueling AMD‘s Success
A key driving force behind AMD‘s recent desktop CPU resurgence is the revolutionary new Zen CPU microarchitecture…
Extracting Every Ounce of Performance
By 2017, AMD‘s Bulldozer architecture had hit a brick wall. To build a worthy successor, AMD engineers scrutinized real-world workloads down to the cycle-level to optimize bottlenecks. Broad improvements were made to the execution pipeline, branch prediction, instruction schedulers, cache hierarchy and simultaneous multi-threading compared to bulldozer.
The Block diagram shows key Zen architecture improvements:
Refining The Core Design Further
AMD has stuck to the basic Zen template through successive Ryzen generations while incorporating newer manufacturing processes for better power efficiency and frequency scaling. The latest Zen 4 cores powering Ryzen 7000 models also added key enhancements:
- Reorganized L2 cache banks per core for higher bandwidth
- Increased dispatch and retire bandwidth by over 50%
- Improved load/store bandwidth to feed the wide frontend
Let‘s analyze specific performance and efficiency gains delivered by each generation built on Zen…
How Ryzen and Core Performance Has Evolved
Chronologically tracing desktop CPU advancements by both Intel and AMD in recent times reveals an intriguing back-and-forth tussle. Whenever one company takes the lead, the other bounces back with an architectural overhaul or new fab process jump to leapfrog their rival once more.
The IPC Race
Instructions executed per clock cycle (IPC) is a measure of architecture efficiency – the higher the better! Here is how IPC has trended in leading Ryzen and Core processors through successive generations:
| Year | Microarchitecture | IPC | process |
|---|---|---|---|
| 2017 | AMD Zen 1 (Ryzen 1000) | 52% over Excavator | 14nm |
| 2018 | Intel Skylake+/Coffee Lake (Core 8000 series) | 11% over Skylake | 14nm++ |
| 2019 | AMD Zen 2 (Ryzen 3000) | 15% over Zen+ | 7nm |
| 2020 | Intel Skylake++ (Core 10000 series) | No IPC change | 14nm++ |
| 2020 | AMD Zen 3 (Ryzen 5000) | 19% over Zen 2 | 7nm |
| 2021 | Intel Alder Lake (Core 12000) | ~20% over Skylake | 10nm |
| 2022 | AMD Zen 4 (Ryzen 7000) | >15% over Zen 3 | 5nm |
The numbers reveal how neck-and-neck the core architecture battle has been recently. With each CPU generation leapfrogging the competition intermittently, consumers reap the fruits of dense competition!
Now let‘s quantify exactly how Ryzen and Core CPU gaming and content creation prowess has matured through these succcessive product cycles…

Matching Top Speeds with Efficient Cores
Another fruitful performance optimization strategy employed by both brands is mixing larger high-power cores with additional smaller efficient cores on processor dies:
- AMD first added this heterogeneous multi-core approach in laptop processors to increase multi-tasking speeds at low power draw.
- Intel took a similar route with their 12th gen Core desktop chips combining Performance cores and Efficient cores on a single package.
Here is a breakdown of the hybrid core configurations across top Ryzen and Core desktop models currently:
| Processor | Big Cores | Small Cores | Process |
|---|---|---|---|
| Ryzen 7 5800X3D | 8 | – | 7nm |
| Core i9-13900K | 8 (P-cores) | 8 (E-cores) | Intel 7 |
In another parallel innovation race between the two CPU titans, adding different core types lets desktop processors maximize both peak throughput and background responsiveness simultaneously within stringent power limits!
Contrasting AMD and Intel‘s Business Approaches
Beyond the technical product feature battles, AMD and Intel‘s wildly differing business strategies and product philosophies are equally fascinating to contrast from an industry perspective.
Their contradicting approaches stem directly from being in opposing positions in the desktop PC ecosystem historically as discussed earlier in this piece.
Intel‘s Platform Control Strategy
As the long-time undisputed market leader, Intel has huge sway on steering ecosystem innovation direction. Here are some business tactics Intel employs to maintain their powerful position:
- Customer funding programs – Intel offers various incentives, discounts and marketing dollars to OEM partners for shipping machines configured with Core processors exclusively.
- Instruction set extensions – Intel actively innovates new CPU instruction set extensions like AVX then makes them proprietary to Cord CPUs only for years before AMD can adopt them. This forces software and compiler developers to optimize primarily for Intel.
- Legal strong-arming – Intel actively threatens litigation against OEMs found violating license terms that often forbid them from dealing with AMD. Anti-poaching employee contracts also lock in talent and constrain AMD.
Overall Intel leverages their dominance to mold ecosystem incentives in a way that best serves their interests. Everything from compilers to operating systems to applications is in turn optimized to run best on Intel‘s CPUs, further cementing their leadership position.
This iron grip has however proven detrimental…
