Salve a tutti i legionari!
Come suggerito da @Sarkhan , voglio sperimentare a pubblicare ogni tanto dei topic di guida e curiosità sul mondo PC e sul gaming in generale, ma che non siano troppo lunghi e dettagliati, quindi inizio proponendovi una piccola prospettiva sui Benchmark.
Il Benchmark è in sostanza una procedura che ci permette di testare le potenzialità del nostro PC per poter confrontare i nostri risultati con altri e per poter vedere se alcune nostre modifiche hanno avuto effetti sullo stesso.
Solitamente in ambito PC abbiamo 3 strade per testare:
- 3D Mark Timespy: misura sia la GPU che la CPU, ma con focus sulla GPU. Disponibile gratuitamente su Steam.
- Cinebench r23: misura in particolare le performance del singolo Core e dei multi-core della CPU. Anch'esso gratuito sul sito dedicato.
- Benchmark proposti sui videogiochi stessi: ricordate che diversi giochi usano diversi criteri di utilizzo del PC. Solitamente si fanno in 1080p e 1440p senza DLSS o RTX per confrontarsi online.
Ovviamente questi test vanno fatti chiudendo tutte le applicazioni possibili ( specie i browser e i videogiochi, ovviamente ) per un test più limpido e chiaro possibile.
Una volta fatto il test solitamente ci si confronta su siti dedicati o banalmente con altri giocatori della propria community, indicando le specifiche del vostro PC. Ecco ad esempio i miei:
@Lascax ciao! Grande, ottimo thread come sempre. Dunque questo è anche un modo per capire a priori se il computer è abbastanza potente per far girare un determinato gioco o programma magari noti per essere belli pesanti?
@Sarkhan Esattamente! Per esempio Timespy a fine test ci dà una pagina web dove possiamo vedere i dettagli del nostro risultato e ci dà anche una nostra "posizione" nel mercato attuale, che viene man mano aggiornata.
Nel mio risultato il Legion 5 Pro 2022 si trova poco sopra High-end Gaming PC, che ovviamente significa che siamo abbastanza certi che in quasi ogni situazione potremo spingere al massimo i nostri giochi:
@Sarkhan
Cliccandoci sopra si può vedere!
Parliamo in sostanza del miglior PC in assoluto disponibile nel 2020, con ben due GPU collegate insieme in parallelo ( tecnologia SLI ).
Qui sta la differenza anche di alimentazione dei desktop, laddove per esempio oggi un laptop di fascia alta arriva a circa 330W al massimo di potenza mentre un desktop supera abbondantemente i 700W, e non deve ovviamente curarsi di limitarsi in temperature e tutto quanto.
Tra l'altro esistono anche risultati ben più mostruosi recenti come questo nella Hall of Fame corrente:
Qui abbiamo non solo un hardware che va ben oltre qualunque necessità anche elitaria ( ben 2 NVidia 3090Ti in SLI ), ma spesso chi li fa arriva a modificare i componenti interni all'inverosimile, arrivando a smontare pure le GPU e le CPU, specie per ottimizzare le temperature.
Addirittura spesso ci si affida anche alla "lotteria del silicio": c'è chi compra GPU e CPU in quantità e le testa per usare quella migliore dove spesso le performance minimamente migliori sono dovute ad una "fortunata" qualità del silicio dei componenti. Robe folli 😂
@Sarkhan Non è detto, anzi, probabilmente andrebbero peggio. E non è affatto una domanda stupida.
In sostanza il Mining viene fatto tramite l'elaborazione di alcuni tipi specifici di dati che non sono quelli comunemente utilizzati per la renderizzazione dei giochi ( per dirla in un modo banale ed estremamente semplificato, stai chiedendo alla GPU di fare calcoli matematici rispetto a disegnare ).
Questo significa che per fare mining e spendere il meno possibile si fanno solitamente queste ottimizzazioni:
CPU meno potente
RAM di qualità minore
Alimentazione in Watt ottimizzata per la GPU ( l'elettricità è il costo più grosso )
SSD e dischi di memoria quasi irrilevanti
Questo significa che i PC sono totalmente diversi come costruzione ( esistono schede madri dedicate, ma anche alcune GPU dedicate ). Però su una cosa c'hai azzeccato: si usa un'altra scala totalmente diversa, cioè l'hash rate ( vedila come potenza di calcolo per il mining ).
Infatti nel periodo in cui le GPU costavano tanto furono fatte le schede GPU con la tag LHR ( Low Hashing Rate ) per disincentivare l'acquisto da parte di miners.
In breve, sì, potresti usare questi PC per fare mining, ma consumerebbero talmente tanta elettricità che potresti andarci in perdita in bolletta ( a prescindere dal mercato attuale, che tra parentesi è un disastro da un bel po' ).
@Lascax super spiegazione come da aspettative, pazzesco comunque! Conosco un ragazzo che ha speso circa 50k per un computer da Mining e poi aveva delle bollette stratosferiche come dici! Comunque pazzesche queste macchine e i consumi che possono avere, avevo letto che il mining del bitcoin nel mondo ha un consumo energetico pari a quello dell'intera argentina o un qualcosa di simile, assurdo!
@Sarkhan Hai portato un esempio lampante. Frotte di persone comuni si sono rovinate per non aver fatto dei giusti preventivi, soprattutto perchè mancavano delle giuste conoscenze tecniche.
Io stesso feci dei preventivi ad un amico in un periodo favorevole e in un contesto dove potevamo abbattere i costi elettrici di tantissimo grazie ai pannelli solari, ma rientrarci era talmente rischioso che un brutto mese nel mercato delle crypto poteva costargli molto caro, e così gli consigliai di lasciar perdere a meno di voler veramente rischiare.
I costi del mining sono disastrosi ecologicamente, e fu qualcosa che studiai poco dopo questo preventivo, e da lì personalmente sono fortemente contro l'abuso speculativo di queste tecnologia ( per non parlare degli NFT, che hanno ulteriori altri problemi anche etici ).
La tecnologia è di per sè uno strumento che può fare bene o male a seconda dell'utilizzo. Attualmente, purtroppo, le blockchain vengono abusate per meri fini monetari a discapito dell'ambiente.
@Lascax mi trovi perfettamente d'accordo, tuttavia credo che la società odierna sia la chiara dimostrazione di come i meri interessi per il dio denaro lasciano etica, morale e rispetto per l'ambiente completamente in secondo piano. Le NFT sono state una meteora davvero veloce a mio parere e molti ci si sono scottati eccome!
Per quanto riguarda il bene e male della tecnologia, credo che un discorso analogo possa essere fatto per l'IA ad esempio, Chat gpt ecc ecc
