The wait is finally over. Both consoles are looking to be attractive offers for different audiences, but it might not be obvious which one is best for your needs. Let's make a quick comparison to get the big picture of what Microsoft is offering come November 10th. The Series S comes with a very similar, but cut-down design.

The CPU is nearly identical, with the core count and architecture features the same between the two systems.

The only difference is a MHz downclock across the board on the cheaper Xbox Series S, a change likely due to the thermal limitations of the smaller system. The GPU is where the biggest difference lie. Microsoft is allowing users to connect 3rd party storage, but due to the speed limitations of external drives, only Xbox One and earlier titles will be playable from the drives.

Another cost-saving measure for the Series S is the console going all digital.

Although backwards compatibility will be the same between the two, users with disc collections of previous generation Xbox games would be forced to buy the games digitally to play on the Series S instead of just popping in the physical copy they already own. The extra cash could go towards purchasing a more games, extra storage, or a year's subscription of Xbox Game Pass Ultimate.

Speaking of subscriptions, Microsoft is bringing their all-inclusive hardware subscription offerings to the new consoles as well.

By releasing two different consoles to kick off the new generation, Microsoft is hoping to have an Xbox offering for everyone. The Series X is targeted to gamers who want the best of best, enthusiasts who care about 4K resolution gaming at FPS. A potentially overlooked audience that the Series X retains by keeping the disc drive are those with multiple generations worth of disc-based Xbox games.

It's a smart move on Microsoft's part, as this group is likely to be older and have more disposable income. It may also make a compelling argument for those who mainly game on PC, even though future first-party titles will be coming to PC. As someone with an Xbox game collection going back to the original system, I find myself tempted to pick up an Xbox Series X to have a system in the living room that supports most of those games at their highest possible quality.

The Xbox Series S seems like a great buy for the more casual gamer who may only play a few titles a year. That is unless Sony comes back swinging with their own budget offering.

Multiple versions of this console have been released since the initial launch of the PS4. Subsequent versions include changes to the technical specifications of the console. Changes to the design included a matte black HDD cover replacing the original gloss black version. While the number of logical processor cores 8 remained the same, CPU clock speed was increased from 1.

Improvements in GPU bit variable float calculations derived from the newer AMD Vega architecture result in the PS4 Pro having a theoretical half precision floating point performance of 8. The PS4 Pro is able to use this increase in memory to swap out non-gaming applications that run in the background, like Netflix and Spotify. GDDR5 memory speed was increased from 5. Some elements added to the design were derived from AMD's newer Polaris and newer architectures; [20] [21] such new features of the processor included a HEVC video codec supporting up to 4k resolution.

The rated power of the original PS4 Pro was W. A limited translucent-case version of the PS4 Pro was released in Augustwhich included minor hardware updates. This new system, model number CUH, besides offering a larger hard drive, used a quieter fan that helped to reduce the noise levels.

It also drew power at a consistent rate compared to the CUH, though became slightly hotter than the launch system. A second minor hardware refresh, with model number CUH, was first released in bundles with Red Dead Redemption 2 in November The newer version, otherwise functionally equivalent to the CUH, has a different power connector, and uses a quieter fan, which, according to Digital Foundrymade a "night and day" difference in the noise level, similar to the improvements in the CUH It further draws power consistently at W, whereas the while rated at W would have brief spikes up to W.

However, the newer console fan runs slightly slower and became slightly hotter than the model to gain this improvement. Though not much is publicly known of the PS4's audio capabilities, the console also contains a dedicated hardware audio module, which can support in-game chat with minimal external resources as well as "a very large number" of MP3 streams for use in in-game audio.

The main APU release had a die size of 19 by That produces a theoretical peak performance of The rest of the microchip consists of the on- die memory controllerwhich is shared by the CPU and the GPU and some additional logic concerned with memory access. This means the system memory is not partitioned, so that a portion of it is exclusively available to the GPU, but unified, hence enabling hardware zero-copy.

Ultra HD Blu-ray for 4K resolution playback is not supported, due to cost. The console does however support photos and videos at 4K resolution. The read-only optical drive also reads DVDs.

It does not read CDs.There were a few select titles where the Ryzen processor came out on top, but for the most part it was only a little slower. Overall it's still a good showing for 3rd-gen Ryzen as the deficit when gaming is negligible for the most part, while it pummeled the K in all productivity tests. Many say this can significantly improve gaming performance Both the SMT on and off configurations are otherwise identical.

The difference against the K was diminished considerably even though the Core i9 was still the faster chip. We see a very small performance regression when testing with The Witcher 3 though again, just a fps difference is within the margin or error. Performance in Far Cry New Dawn went virtually untouched, at least we see the same fps on average.

Frankly, results are well within the margin or error Hitman 2 is always an interesting title that stands out for one reason or another. Performance in The Division 2 was pretty much identical with out without SMT support, at least when looking at the average frame rate.

Testing Ryzen 9 with SMT On vs. SMT Off

Disabling SMT certainly looks to be a mixed bag, and we tried to go title by title but we have results for even more games that we tested, starting with the average frame rate results. Just as we found two years ago when testing the Ryzen 7 X, disabling SMT can be of some benefit but your mileage will vary and depend strictly on the game workload and is just as likely to cause a regression in performance.

It also runs much cooler, consumes a little less power, and works fine with the provided stock cooler.

Nintendo had nothing in the pipe and Sony was staying quiet about the PlayStation 5, which gave Microsoft plenty of room to talk about the capabilities of its Xbox Series X. Sony is finally opening up about the capabilities of its console and how some of the features will work. There are 36 GPU compute units running at up to 2. There are two particularly interesting facets of what Sony unveiled today.

First is how Sony is using boost. PC turbo clocks are unique to the configuration of any given system and can vary depending on chip quality and system cooling. Sony still expects the PlayStation 5 to play games identically across every console. The first part of this is absolutely true.

Teraflops is an absolutely terrible way to compare GPU performance. The second part is a little more complicated. As a friend of mine says, a rising tide lifts all boats. The faster you want to run, the more voltage you need. Eventually, these become major limiting factors. The PlayStation 5 will offer up to 5.

Obviously PCIe 4. Remade versions of old games with long transitions and load times removed might be very popular next generation. Games now have the ability to flag certain data blocks with up to six priority levels, meaning developers have fine-grained control over which data is loaded.

The entire storage pool is connected by an x4 PCIe 4. This site may earn affiliate commissions from the links on this page. Terms of use. Post a Comment Comment.

SMT permits multiple independent threads of execution to better utilize the resources provided by modern processor architectures. Although running on the same core, they are completely separated from each other. Multithreading is similar in concept to preemptive multitasking but is implemented at the thread level of execution in modern superscalar processors. Simultaneous multithreading SMT is one of the two main implementations of multithreading, the other form being temporal multithreading also known as super-threading.

In temporal multithreading, only one thread of instructions can execute in any given pipeline stage at a time. In simultaneous multithreading, instructions from more than one thread can be executed in any given pipeline stage at a time. This is done without great changes to the basic processor architecture: the main additions needed are the ability to fetch instructions from multiple threads in a cycle, and a larger register file to hold data from multiple threads.

The number of concurrent threads can be decided by the chip designers. Two concurrent threads per CPU core are common, but some processors support up to eight concurrent threads per core.

Because it is really an efficiency technique that inevitably increases conflict on shared resources, measuring or agreeing on its effectiveness can be difficult. That is, even when performance gains are minimal the power consumption savings can be considerable.

Some researchers [ who? Others [ who? However, in most current cases, SMT is about hiding memory latency, increasing efficiency, and increasing throughput of computations per amount of hardware used. In processor design, there are two ways to increase on-chip parallelism with fewer resource requirements: one is superscalar technique which tries to exploit instruction level parallelism ILP ; the other is multithreading approach exploiting thread level parallelism TLP.

Superscalar means executing multiple instructions at the same time while thread-level parallelism TLP executes instructions from multiple threads within one processor chip at the same time.

There are many ways to support more than one thread within a chip, namely:. The key factor to distinguish them is to look at how many instructions the processor can issue in one cycle and how many threads from which the instructions come.

Xbox Series S vs Series X spec-by-spec comparison

For example, Sun Microsystems' UltraSPARC T1 is a multicore processor combined with fine-grain multithreading technique instead of simultaneous multithreading because each core can only issue one instruction at a time.

The microprocessor was never released, since the Alpha line of microprocessors was discontinued shortly before HP acquired Compaq which had in turn acquired DEC. The Intel Pentium 4 was the first modern desktop processor to implement simultaneous multithreading, starting from the 3.

The performance improvement seen is very application-dependent; however, when running two programs that require full attention of the processor it can actually seem like one or both of the programs slows down slightly when Hyper-threading is turned on.Enhanced upscaling techniques can increase game resolutions to approach 4K.

Distant background objects benefit from improved focus and become more visible and detailed. Images with soft features - like rounded corners and faces - appear smoother and more realistic. Visual elements with very small features - like smoke and steam - have a heavier look and more realistic feel.

He showed holes that Rigondeaux can exploit. Rigondeaux never fights, always boxes. I see him draining the Cuban and then overwhelming him. Joseph Agbeko (ex two time IBF bantam champion) told me Rigondeaux punches brutally hard.

Lomachenko already has one loss on his record and will lose again.

A good big fighter beats a good little fighter and Lomachenko could even stop him. I see him winning by stoppage somewhere around the eighth or ninth. He attacks from angles rather than straight lines. Rigondeaux is very patient on the back foot and has exceptional timing but I think Lomachenko will be too busy and too big physically.

What a match up. No one has more ability than this pair. Both have got talent pouring out of their ears. Both have got great attributes and can win any fight on their best day.

Rigondeaux is the more experienced and very sharp. He might be able to catch Lomachenko and deliver the knockout blow. So, IOW, after the fight ends, there will either be 11 experts who are no longer experts, or 3 experts who are no longer experts. My head is spinning.

And someone posted yesterday that around the time of the weigh-in, Vegas odds were 2. He's too good for him. Tags: Vasyl Lomachenko Guillermo Rigondeaux Lomachenko vs.
