Labadii bilood ee la soo dhaafay, waxaan wax badan ka maqalnay RDNA 2^{(RDNA 2)} halkaasoo jiilka soo socda ee ciyaarta fiidiyowga ay ka walaacsan yihiin, gaar ahaan Xbox Series X/S . Waxaa loogu talagalay in lagu bixiyo waxqabadka si weyn loo hagaajiyay marka loo eego tignoolajiyada GCN ee loo adeegsaday consoles-yadii hore.

RDNA 2 kaliya kama faa'iidaysan doonto jiilka soo socda consoles-yada, kuwaas oo hadda, loo arko jiilka hadda jira maadaama ay hadda diyaar u yihiin dadweynaha guud.

Waa maxay RDNA 2

Hagaag, waa tignoolajiyada AMD oo u taagan Radeon DNA , waana aasaaska sawirada sawirada halka jiilka soo socda ee ciyaaraha PC, Xbox Series X/S , iyo PlayStation 5 ay walaac ka qabaan. Sidoo kale waa ku-xigeenka RDNA , oo la sii daayay July 7 , 2019, taas oo aan aad uga fogayn waagii hore, dhammaan waxyaalihii la tixgeliyey.

Marka loo eego dadka ka shaqeeya AMD , naqshadeeda cusub ee RDNA GPU waxay keeni kartaa ilaa 50 boqolkiiba waxqabad dheeraad ah marka la barbar dhigo nooca 1, iyo ilaa 100 boqolkiiba marka la barbar dhigo GCN . Ma aha taas oo keliya, laakiin tignoolajiyada cusubi waxay taageertaa raadinta raajo, oo ah sifada inta badan looga hadlo ciyaaraha.

Hadda, tignoolajiyadu waxa kale oo ay taageertaa Infinity Cache , shader-ka-hoosaadka, hooska-beddelka, iyo jawaab celinta muunada.

Waxaa jira qaybo ka mid ah RDNA 2 oo la mid ah RDNA 1. Midda ugu cad ayaa ah habka wax soo saarka ee ku salaysan TSMC 7nm . Guud ahaan, baloogyada udub dhexaadka u ah nooca cusub ee RDNA waxay la mid yihiin kii asalka ahaa, iyada oo faraqa ugu weyni uu yahay taageerada raadinta raajada ee ku salaysan qalabka.

Waa maxay RDNA 2 Infinity Cache

Waxaa jira hal shay oo kale oo xiiso leh oo ku saabsan tignoolajiyadan wax-soo-saarka ah ee aan u baahanahay inaan ka wada hadalno, waxaana loo yaqaan ' Infinity Cache ' . Waxa aan halkan ku hayno asal ahaan waa kayd weyn oo 128MB L3 ah kaas oo loo habeeyay culeysyada shaqada ciyaarta.

Waxaan fahamsanahay inay ka cufan tahay L3 RAM illaa afar jeer, iyo sababta ugu weyn ee tan waa in lagu caawiyo waxtarka. Hadda, marka tan lagu daro GPU , waxay asal ahaan ka hortagtaa inay u soo dirto calaamadaha dhammaan habka xirmada xusuusta inta badan kiisaska.

Samaynta tan waxay ka dhigaysaa Infinity Cache mid awood badan oo dhakhso badan marka la barbar dhigo kordhinta ballaca baska ee qaybaha xusuusta.

Aynu ka hadalno Raadinta Ray

Sidaan kor ku soo sheegnay, RDNA 2 GPU^(GPUs) -yadu waxay taageeri doonaan raadinta rayaha ku salaysan qalabka, tanina waa heshiis aad u weyn. Haa, AMD waxaa ku garaacday feerka Nvidia , iyo waxa aan ku sheegi karno warbixinno dhowr ah ilaa hadda, tignoolajiyada raadraaca ee Nvidia ayaa aad u qaangaar ah waqtigan.

Si kastaba ha ahaatee, taasi macnaheedu maaha RDNA 2 ma samaynayso cadaalad. Waxaad aragtaa, radeon RX 6000 oo ay la socdaan kuwa laga heli karo consoles-yada jiilka soo socda, dhamaantood waxay leeyihiin "dardariyaha ray" u go'an oo ku dheggan cutub kasta oo xisaabiye ah.

Sida ay hadda taagan tahay, si kastaba ha ahaatee, AMD jawaab uma hayso Nvidia 's Deep Learning Super Sampling ( DLSS ), tignoolajiyada, taas oo macnaheedu yahay, kaararka Nvidia waxay yeelan doonaan gees, laakiin taasi ma noqon karto kiiska halka Xbox Series X/S ayaa ka walaacsan.

Waxaad arkaysaa, Microsoft oo ay weheliso AMD waxay ka shaqaynaysaa nooca u gaar ah ee DLSS ee loo yaqaan DirectML , sidaas darteed waxaan arki karnaa qaar la yaab leh mustaqbalka fog.

Taageerada DirectX 12 Ultimate

RDNA 2 waxay taageertaa dhamaan sifooyinka uu DirectX 12 Ultimate keeno miiska, qaar ka mid ah sifooyinkaasna waxaa ka mid ah kuwa jecel shahing-ka, hooska-beddelka, iyo jawaab celinta muunada. Tani waxay la macno tahay, horumariyayaashu waa inay la kulmaan waxqabadka kordhay, taasina waxay u fiican tahay macaamiisha.

Ma aha oo kaliya, laakiin AMD GPU^{(AMD GPUs)} -yadu waxay u taagan yihiin inay taageero u helaan DirectStorage API ^{(DirectStorage API)}Microsoft . Waxaan fahamsanahay in API -ga loogu talagalay inuu u oggolaado NVMe SSD kaaga inuu si toos ah ula hadlo kaarka garaafyada. Marka ay tani dhacdo, ciyaartoydu waa inay arkaan kororka wakhtiyada rarka iyo qulqulka hantida.

Xbox Series Xbox Series X/S shaki kuma jiro inuu tan ka faa'iidaysan doono si uu ula socdo xawaaraha aadka u dheereeya ee SSD ee laga helo PlayStation 5 .

What is RDNA 2 and how will it affect the future of AMD gaming

Over the past couple of months, we’ve bеen hearing a lot abоut RDNA 2 where the next-generation video game consoles are concerned, especially the Xbox Series X/S. It is designed to deliver significantly improved performance over the GCN technology that was used in the previous consoles.

RDNA 2 won’t just benefit the next generation consoles, which as of right now, are deemed as current generation since they are now available for the general public.

What is RDNA 2

Well, it’s an AMD technology that stands for Radeon DNA, and it is the foundation for graphics rendering where next-generation PC gaming, Xbox Series X/S, and PlayStation 5 are concerned. It is also the successor to RDNA, which was released on July 7, 2019, which is not very far away in the past, all things considered.

According to the folks at AMD, its new RDNA GPU architecture can deliver up to 50 percent more performance when compared to version 1, and up to 100 percent when compared to GCN. Not only that, but the new technology supports ray tracing, a feature much talked about in gaming as of late.

Now, the tech also supports Infinity Cache, mesh shaders, variable-rate shading, and sampler feedback.

There are some aspects of RDNA 2 that are similar to RDNA 1. The most obvious is the manufacturing process that is based on the TSMC 7nm. Overall, the core building blocks of this new version of RDNA is relatively the same as the original, with the main difference being the hardware-based ray tracing support.

What is RDNA 2 Infinity Cache

There is one more interesting thing about this rendering technology that we need to discuss, and it is called Infinity Cache. What we have here is basically a massive 128MB L3 cache that has been customized for gaming workloads.

We understand that it is denser than L3 RAM by up to four times, and the primary reason for this is to aid with efficiency. Now, when this is added to a GPU, it basically prevents it from sending signals all the way across the package to the memory in most cases.

Doing this makes the Infinity Cache more power-efficient and faster compared to just increasing the bus width to the memory modules.

Let’s talk about Ray Tracing

As we’ve mentioned above, RDNA 2 GPUs will support hardware-based ray tracing, and this is a huge deal. Yes, AMD was beaten to the punch by Nvidia, and from what we can tell via several reports so far, the Nvidia ray tracing tech is more mature at this time.

However, that doesn’t mean RDNA 2 won’t do it justice. You see, the Radeon RX 6000 stack along with the ones available in next-generation consoles, all have a dedicated “ray accelerator” attached to each compute unit.

As it stands right now, however, AMD does not have an answer to Nvidia’s Deep Learning Super Sampling (DLSS) technology, which means, Nvidia cards will have an edge, but that might not be the case where the Xbox Series X/S is concerned.

You see, Microsoft alongside AMD is working on their own version of DLSS known as DirectML, so we could see some surprises in the distant future.

Support for DirectX 12 Ultimate

RDNA 2 supports all the features that DirectX 12 Ultimate brings to the table, and some of those features include the likes of mesh shading, variable-rate shading, and sampler feedback. This means, developers should experience increased performance, and that is good for consumers.

Not only that, but AMD GPUs stand to gain support for DirectStorage API from Microsoft. We understand that this API is designed to allow your NVMe SSD to talk directly with your graphic card. When this happens, gamers should see an increase in loading times and asset streaming.

The Xbox Series X/S will no doubt benefit from this to better keep pace with the much faster SSD found in the PlayStation 5.
