You may configure your Stratosphere Mini Z4 system with any of the CPUs below:

Intel Core i3 (9th Gen)

• 4 cores processing 4 simultaneous threads
• Intel Core i3-9100F (standard): 3.6 - 4.2 GHz

Intel Core i5 (9th Gen)

• 6 cores processing 6 simultaneous threads
• Intel Core i5-9400F: 2.9 - 4.1 GHz

Intel Core i7 (8th Gen)

• 6 cores processing 12 simultaneous threads
• Intel Core i7-8700: 3.2 - 4.6 GHz

Intel Core i7 (9th Gen)

• 8 cores processing 8 simultaneous threads
• Intel Core i7-9700F: 3.0 - 4.7 GHz

Intel Core i9 (9th Gen)

• 8 cores processing 16 simultaneous threads
• Intel Core i9-9900: 3.1 - 5.0 GHz

Intel's 9th Generation Core i3, Core i5, Core i7 and Core i9 processors take a huge leap forward, with at least a 30% improvement in performance compared to the prior generation, according to PassMark CPU Mark and other benchmark tests.

Most of this jump in performance comes through the use of up to eight CPU cores within each processor, up from four or six in the prior generation. With more cores, more work can be done in parallel, enabling smoother multitasking, more responsive financial trading indicators, and even faster web browsing when many tabs are open.

A primer on CPU terminology:
How cores, threads and multithreading affect performance

Modern multi-core CPUs split up your computer's tasks across a team of processors that work in parallel, like a team of horses. Two horses are better than one; four are better than two; the more horsepower, the better. For CPUs, your workhorses are etched in silicon all within a single chip, and we call those workers CPU cores.

Of course, CPUs don't always run in one direction like a team of horses. Think of CPU cores as a team of cooks in a central kitchen, with CPU threads being the waiters bringing in orders (instructions) and returning with cooked (processed) food.

A kitchen's productivity is thus roughly equal to the number of cooks and the speed of each cook. For CPUs we call that speed the clock speed of each core, which can vary independently during operation. CPU clocks are measured in GHz (gigahertz), so a 3GHz CPU is operating at three billion cycles per second. Cores act as a multiplier to clock speed, since the cores work independently, and each core also executes multiple instructions in parallel.

You'll notice that CPU clock speed is often expressed as a range. The low number, or base clock speed, is the guaranteed minimum speed of all cores. The high number is Intel Turbo Boost: the peak clock speed that one or several cores can achieve for a limited period without overheating the CPU. Intel CPUs with Turbo Boost will automatically increase the speed of individual cores to process demanding threads to the fastest extent possible without crossing thermal limits or exceeding the preset Turbo Boost limit.

Each CPU core independently executes operating system requests and is addressed as a separate CPU. This is a bit like having a a dedicated waiter for each cook in the kitchen. However, when a cook handles two waiters' orders simultaneously, he's more productive. Now the restaurant can serve more customers at the same time, simply by hiring more waiters.

A team of cooks: which ones are virtual?

In the same way, Intel CPUs with Hyper-Threading Technology can process two software threads simultaneously by presenting two logical CPUs to the operating system for each physical core. Faking extra CPU cores is a workload management technique, so a CPU core can keep working even if a thread is waiting for external data or is stalled. Hyper-Threading is like having two waiters available for the same cook. Other waiters may be too busy to take your order, but this waiter is available, and then so is the actual cook. Just as a team of cooks is more productive with twice the wait staff serving the demands of patrons, Hyper-Threading enables CPU cores to process more threads by working around bottlenecks and resource hogs. Waiters serve as workload managers for the cooks, and so does Hyper-Threading for CPUs.

Intel's 9th Generation Core processors unleash faster performance than ever, with faster clock speeds, more cores, more virtual cores (measured by thread count), and more performance per dollar. At the top of line, Intel Core i9 processors deliver 8 CPU cores processing 16 simultaneous threads, at record stock clock speeds up to 5GHz.

One rung down, 9th Gen Intel Core i7 processors also include 8 CPU cores for the first time, while not offering Hyper-Threading. The very successful 8th Gen Core i7 series (Core i7-8700) follows one further rung down in performance, with 6 CPU cores handling 12 simultaneous threads.

Meanwhile, affordable 9th Gen Intel Core i5 CPUs reach new highs in peak clock speed for this affordable price point while still delivering an impressive six CPU cores. Finally, 9th Gen Core i3 processors deliver great quad-core performance for a fraction of the price that this performance cost only a few years ago.

With more cores and more simultaneous threads, more work can be done in parallel, enabling smoother multitasking, more responsive financial trading indicators, and even faster web browsing when many tabs are open. There's a 9th Gen Intel Core processor to meet every requirement and budget. Choose yours by customizing Stratosphere Mini Z4 and pricing your complete configuration today!

Q: Why do some Intel CPU names end with K, F or KF?

A: Intel uses the K suffix to designate "unlocked" CPUs, of particular interest to gamers and overclockers. Overclocking enthusiasts run these CPUs at higher clock speeds than Intel guarantees, typically aided by liquid cooling, and typically with the goal of running games faster. However, K-series CPUs also ship with a faster base clock and Turbo Boost than non-K sibling models. These faster clock speeds are guaranteed by Intel without resorting to overclocking, so K-series CPUs naturally appeal to any power user looking for better performance.

Intel recently started shipping F-series CPUs, which have their internal graphics subsystem (Intel UHD Graphics 630) permanently disabled. F-series CPUs are used on systems with discrete graphics cards, which are the vast majority of the systems we sell. F-series CPUs are helping relieve supply constraints (inadequate manufacturing yields) on many standard Intel CPUs in the past year, which have caused order fulfillment delays across the industry. PassMark CPU Mark benchmarks suggest that the F-series models on average perform slightly faster than non-F models.

Finally, KF-series CPUs are unlocked processors with their graphics subsystem disabled.
